A 5‐year‐old female cross‐breed dog was presented for a one‐month history of lethargy, poor appetite and weight loss. A hysterectomy had been performed 2 years ago. Abdominal palpation revealed a mid‐abdominal mass and haematological analysis showed leucocytosis with left shift. On abdominal radiographs, a 9 cm in diameter soft tissue opacity mass ventral to the colon and caudal to the left kidney was observed. The abdominal ultrasonography revealed a mass well circumscribed, with a hyperechoic capsule and hypoechoic center with echoic debris. The presumptive diagnosis was an abscess due to foreign body granuloma. Laparotomy was performed and a mass close to the left ovary was found. Adhesions and residues of the suture material were observed close to the right ovary and the uterine body stump. The mass, both ovaries and adhesions were removed. On cut section of the mass two cavities were observed. The small one contained three embedded silk suture residues. Histopathological examination confirmed the diagnosis of a chronic abscess caused by silk suture.  相似文献

A 11-year-old, spayed, female mixed breed-dog was presented with an abdominal mass that was detected 1 month ago. Upon abdominal palpation a large, firm, oval shaped, movable mass was found in the mid-abdominal region. Survey radiograph of the abdomen demonstrated an oval soft tissue dense mass located on the right side of the abdominal cavity. A large, heteregenous and cystic mass with solid components occupying the majority of the abdomen and a small, cystic mass with solid components caudal to the left kidney were identified by transabdominal ultrasonography. Computed tomography scans revealed bilateral ovarian masses, and a small volume of retroperitoneal fluid on the right side. A cystic, but otherwise solid mass located in the right ovary and small retained left ovary encapsulated in the ovarian bursa were excised surgically by midline laparotomy. Histopathological examination of the excised mass from the right side revealed a large cystic structure consistent with an ovarian cyst and multiple corpora lutea and follicles at different maturational stages were detected in the left ovary. The precise origin of the ovarian cyst could not be determined by morphological appearance. Immunohistochemical staining suggested a cyst of surface epithelial origin. At re-examination 6 months after the surgery, the bitch appeared healthy and the clinical findings were all normal. To our knowledge, the cyst described here is the largest reported in an incompletely ovariohysterectomized bitch.  相似文献

This report describes multiple endocrine neoplasia in a dog, which is a rare hereditary disorder characterized by the presence of two or more neoplasms of different endocrine tissues within a patient. A 14 yr old dog was evaluated for polyuria/polydipsia, polyphagia, and abdominal enlargement. Adrenal-dependent hyperadrenocorticism with concomitant left thyroid enlargement and a presumed abdominal metastatic lesion were diagnosed by an adrenocorticotropic hormone stimulation test, ultrasonography, and computed tomography. Trilostane therapy was initiated and resolved the clinical signs for 2 yr at which time the dog presented with left testicular enlargement. The dog was euthanized and was diagnosed with adrenocortical carcinoma, thyroid carcinoma, an abdominal mass compatible with a metastatic lymph node, and bilateral interstitial cell testicular adenomas. To the authors' knowledge, this is the first report to describe the concomitant association of these types of endocrine neoplasms in a dog. The concomitant presence of these neoplasms could represent a potential variant of multiple endocrine neoplasia; however, the presence of the interstitial cell testicular adenomas may have only been an incidental finding. If any of these tumors are diagnosed, veterinarians should perform a thorough clinical assessment to evaluate for the presence of additional endocrine neoplasms or hyperplasia.  相似文献

A desexed female ferret was presented with bilateral alopecic changes. Clinical examination revealed generalized alopecia and abdominal distension. A polycystic mass was found behind the right kidney, and the whole abdomen was filled with a large turgid mass. Radiography and ultrasonography confirmed the presumptive diagnosis of a hydrometra. Hematology and serum biochemistry showed regenerative anemia with light azotemia. Laparotomy showed the presence of a neoplastic mass at the location of the right ovary, a massive enlargement of the uterus filled with a clear fluid, and a subcapsular cyst on the left kidney. After surgery, histopathologic examination of the tissues diagnosed a leiomyoma of the right ovary with hyperplasia of the uterine wall.  相似文献

A 10-year-old male maltise dog was presented for evaluation of a gradual abdominal enlargement, which had developed over 2 years. (On the radiograph of the abdomen, a significant distention of the abdomen with a large accumulation of fat could be seen.) The mass effect was noticeable because of the rightward displacement of the viscera. There was multifocal amorphous mineralization, mostly in the right abdomen. Computed tomography (CT) identified a 13 x 13 x 10 cm mass, most likely an intra-abdominal lipoma, by which the digestive tract had been displaced in the abdomen. It was only during surgery, however, that the mass was found to be located between the peritoneum and transversus abdominis muscles and the rectus abdominus muscle. It was completely resected. Histopathological examination revealed that the mass was chondrolipoma. The amorphous radiopaque lesion on the images corresponded to cartilaginous tissues with calcification. There has been no recurrence for 10 months. This is the first report of an extra-abdominal chondrolipoma in dogs. Cartilaginous metaplasia of lipoma, located in the abdominal area, should be included in the differential diagnosis for multifocal amorphous mineralization.  相似文献

Four dogs with clinical evidence of hyperadrenocorticism were evaluated by use of x-ray-computed tomography (CT). Adrenal masses were identified accurately and localized. Unilateral adrenal masses were diagnosed accurately in dogs 1, 2, and 3 and were removed surgically via a paracostal retroperitoneal approach to the adrenal gland. Using CT and IV contrast medium, the adrenal mass in dog 3 also was accurately diagnosed as being highly vascular. The histopathologic diagnosis was adrenal adenoma in dogs 1, 2, and 3. In dog 4, the CT-roentgen diagnosis was asymmetric bilateral adrenal enlargement. Necropsy examination of dog 4 indicated moderate enlargement of the left adrenal gland and severe enlargement of the right adrenal gland. Results of microscopic examination indicated chronic inflammation of the left adrenal gland and adenocarcinoma of the right adrenal gland. Use of CT facilitated localization of adrenal masses and fulfilled the needs of a localizing technique. A unilateral mass can be removed surgically via a limited exposure, retroperitoneal incision on the affected side of the animal instead of removal via abdominal laparotomy, which is more invasive. Advantages of CT can reduce the needs of other imaging modalities for the localization of adrenal masses.  相似文献

A 13‐year‐old female Pointer dog was presented for evaluation of mammary tumours and bloody vaginal discharge at the Veterinary Teaching Hospital of Mehmet Akif Ersoy University, Faculty of Veterinary Medicine. On the history, owner complained of mammary tumours and bloody vaginal discharge. Three mammary tumours and lymphadenopathy at the mammary lymph nodes were observed at the clinical examination. A big, firm, palpable mass was found in the abdominal cavity. Vaginal cytology revealed numerous pleomorphic and anaplastic cells. Abdominal ultrasonography demonstrated a large mid‐abdominal mass at the distal part of the left uterine horn. Also multiple masses in the cervix and vagina were found. Because of the poor prognosis and the desire of the owner, the bitch was killed. At the necropsy numerous masses were seen at the vagina and cervix and one big mass seen at the left cornu uteri. Histopathological diagnosis was leiomyoma. Multiple metastases of mammary tumours were seen at the lungs. Histopathologically, mammary tumours were diagnosed as complex type tubulopapillary adenocarcinoma. The objectives of this study were to measure the proliferation indices in canine complex type mammary adenocarcinoma and genital leiomyomas using immunohistochemical detection of Ki‐67 and proliferating cell nuclear antigen to determine the relationship of these antigens to clinical and pathologic variables; and to examine the immunoreactivity of these tumours with different markers. Pan‐cytokeratin and S100 were negative, desmin and glial fibriler acidic protein were slight positive and the other markers (carsinoembryogenic antigen, proliferating cell nuclear antigen, vimentin, smooth muscle actin, p53, fibronectin, Ki67) were found strong positive at the genital tumours. Only desmin were negative; the other markers were strong positive at the mammary tumours.  相似文献

A 17‐month‐old male Labrador retriever presented for evaluation of an abdominal mass felt during abdominal palpation. Multiple variably sized cystic masses were identified on sonographic and radiographic images. Exploratory laparotomy revealed multiple peritoneal masses that exhibited atypical contractions and lacked an identifiable organ of origin. Histology and immunohistochemistry of multiple surgically excised masses was consistent with benign tumors of smooth muscle origin (leiomyomas). The presence of multiple peritoneal leiomyomas in this dog is consistent with disseminated peritoneal leiomyomatosis. Two years after diagnosis and multiple surgical interventions, continual insidious enlargement of leiomyomas was identified on ultrasound and CT.  相似文献

Rapid abdominal enlargement and weight gain occurred in a four-year-old Rhodesian ridgeback bitch in late oestrus. The bitch was nulliparous. Severe cardiovascular dysfunction followed and an exploratory laparotomy was performed. A large, single, spheroid mass weighing 17 kg was located in the middle section of the left uterine horn. A diagnosis of sterile, focal, cystic endometrial hyperplasia was made from gross pathology, histopathol-ogy and bacteriology. The bitch made a complete recovery following an ovariohysterectomy.  相似文献

A 10-year-old Jack Russell terrier bitch and a nine-year-old standard dachshund bitch were presented with abdominal enlargement and weight increase; neither had a history of ill health. In each case an extensive soft tissue mass was clearly palpable in the abdomen and following an exploratory laparotomy a partial hepatectomy was performed. Both bitches made a good postoperative recovery followed by a normal active life. In each case the survival time was six months before renewed tumour development lead to a sudden and rapid decline; case 1 was euthanased and case 2 died peacefully.  相似文献

A retrospective review was performed on 14 cats with histology- or cytology-proven carcinomatosis. The mean age was 12.7 years with a median of 11 years. The diagnosis of carcinomatosis was made by histology in 11 cats and cytology in three cats. Twelve cats had cytologic examination of the peritoneal free fluid and seven cats (58.3%) had evidence of malignant cells. The primary tumor site was determined in 13 cats. The most common organ locations for the primary tumor were the liver (n = 5), pancreas (n = 3), and small intestine (n = 3). Other sites were stomach and spleen in one cat each. Epithelial cell neoplasia was the primary tumor type in 11 cats. Two cats had abdominal lymphomatosis and one cat had abdominal sarcomatosis secondary to metastatic hemangiosarcoma. Free peritoneal fluid and masses in the connecting peritoneum were found in all cats (100%). Additional findings included primary or metastatic masses in abdominal organs in 10 cats (71.4%), lymph node enlargement in five cats (35.7%), pleural effusion in three cats (21.4%), parietal peritoneal masses in two cats (14.3%), and visceral peritoneal masses in one cat (7.1%). Masses in the connecting peritoneal may be a very specific finding for carcinomatosis in cats, especially with a concurrent abdominal neoplastic mass. Parietal and visceral peritoneal masses, while uncommon in this series of cats, have not been reported for other diseases and seem to strongly support a diagnosis of carcinomatosis.  相似文献

A 12‐year‐old Peruvian Paso stallion was examined for scrotal swelling and unilateral testicular enlargement of 4–6 weeks duration. Physical examination and ultrasonography of the scrotum revealed an enlarged, nonpainful right testis with a well encapsulated mass at the cranial‐medial aspect containing echodense flocculent material. Unilateral castration was performed and the testis, spermatic cord and vaginal tunic were submitted for histological examination, which revealed a mastocytoma with accompanying evidence of malignancy. Short‐term follow‐up examination did not reveal any evidence of abdominal metastasis and the stallion has since successfully achieved pregnancy in a small number of mares. Although considered rare, mast cell neoplasia should be considered as a differential diagnosis when unilateral testicular enlargement is encountered.  相似文献

A seven-year-old Labrador Retriever with behavioural change, mental depression, lethargy, abdominal enlargement and small testes was found to have bilateral adrenal hyperplasia secondary to an ACTH-secreting pituitary tumour which encroached on the hypothalamus and thalamus. Additional hormonal abnormalities detected were hypothyroidism, deficiencies of gonadotrophins and testosterone, and impaired growth hormone response to insulin infusion.  相似文献

A seven-year-old entire female, mixed-breed dog, weighing 19 kg, was presented with a 2-day history of abdominal distension, reduced appetite and general dullness. Abdominal palpation revealed a large mass. Radiography showed a large mass occupying the left mid-abdominal area and convoluted loops of tubular fluid opacity occupying the right mid-abdominal area. Ultrasonography revealed a large heterogeneous mass with an anechoic area and some hyperechoic foci, indicative of calcification, in the mid-abdominal area. Furthermore, hypoechoic areas were found in the middle and caudal abdominal area and were presumed to be the fluid-filled uterine horns. At laparotomy, a 10·5×14·5-cm firm mass was found in the uterine body, while the uterine horns were filled with a thick red-brownish exudate; ovariohysterectomy was subsequently performed. A diagnosis of uterine leiomyosarcoma associated with pyometra was established by histopathology and immunohistochemistry.  相似文献

An unusual case diagnosed as connective tissue-type mast cell leukemia with marked mastocyte infiltration into visceral organs in a seven-year-old female Curly-Coated retriever is presented. Acute circulatory collapse, emesis, diarrhea, abdominal enlargement, icterus, cyanosis, dyspnea, pulmonary edema, hepatomegary, ascites, and right ventricular enlargement were observed. Hematologic and biochemical examinations revealed mast cell leukemia, mature neutrophilia, monocytosis, thrombocytopenia, hemolytic hyperbilirubinemia, hyperhistaminemia, renal and hepatic injuries. Mast cells were distributed systemically, but predominantly in the diaphragm and liver with a large mass among the serosa of ileum, cecum and colon. Mast cells were stained intensely by both safranin and berberine sulfate.  相似文献

A 20-year old male cotton-top tamarin (Saguinus oedipus) was presented with unilateral enlargement of an intrascrotal testicle. Fine-needle aspiration cytology demonstrated a neoplastic population with Call-Exner-like bodies and features of malignancy. The animal was castrated, and histologic examination revealed a biphasic sex cord-stromal tumor, with one region resembling Sertoli-cell tumor and one region resembling granulosa-cell tumor, with extensive microfollicular pattern and many Call-Exner bodies. Eight months after castration, the animal was euthanized on discovery of a caudal abdominal mass that displaced organs, was highly infiltrative, and extended into the paravertebral musculature with lysis of vertebral bone. Metastases to lymph node and lung were also present. Histologic examination of the abdominal tumor showed multifocal formation of Call-Exner bodies in an otherwise highly dedifferentiated population. Positive immunolabeling for alpha inhibin confirmed the sex cord-stromal origin of the abdominal and paravertebral tumor masses. This case has similarities to malignant testicular granulosa-cell tumor of humans.  相似文献

OBJECTIVE: To evaluate changes over time in echocardiographic measurements in young Standardbred racehorses undergoing training and racing and determine whether there was any relationship between cardiac dimensions and racing performance. DESIGN: Longitudinal observational study. ANIMALS: 103 horses. PROCEDURE: 2-dimensional and M-mode echocardiography was performed 4 times at 6-month intervals. RESULTS: Significant cardiac enlargement took place during the study period as indicated by increases in left ventricular internal diameter in diastole (LVIDd), estimated left ventricular muscle mass (LV mass), and mean wall thickness attributable to eccentric left ventricular hypertrophy. Estimated body weight was positively correlated with left ventricular size, and males had significantly larger LVIDd and LV mass than did females. Horses that were racing regularly had larger LVIDd and LV mass than did unraced horses. A significant relationship between left ventricular size and racing performance was observed. The relationship was strongest at the time of the fourth examination. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that age must be taken into account when interpreting results of echocardiography in young Standardbred racehorses because significant cardiac enlargement takes place with age and training. A larger heart was found in horses that were racing, and size of the heart was correlated with athletic performance of the horse.  相似文献

A male 8-year-old Yorkshire Terrier dog with unilateral cryptorchism was presented for investigation of reduced appetite and multifocal alopecia. Abdominal sonography and radiography demonstrated abnormal enlargement of left testicle in abdominal cavity. Both of the retroperitoneal cryptorchid testicle and the other contralateral testicle were removed surgically. The concentrations of testosterone and estradiol in blood collected from the jugular vein and the two spermatic veins were evaluated and the results revealed high estradiol concentration. The retroperitoneal cryptorchid testicle was enlarged, firm, bulging sphere mass. The cut surface revealed homogeneous white color and lobulation by septa. The contralateral testicle in scrotum showed atrophic testicle and enlarged epididymis. Histopathologically, the retroperitoneal cryptorchid testicle was diagnosed as seminoma. We thought that hyperesterogenemia and alopecia in this case was probably related with his seminoma, although high correlations between Sertoli cell tumor and alopecia have been reported. To our knowledge, this report may be a rare case of seminoma with hyperesterogenemia and alopecia.  相似文献

A female cockatiel had a 2-week history of abdominal distention, lethargy, and diarrhea. The cockatiel had a history of frequent egg-laying, and the owner suspected that she was egg-bound. A solid mass was removed through the cloaca and found to be a concretion of urates that had formed within a hernial pouch of the caudal abdominal musculature. Diagnosis was aided by contrast radiography, and surgery was performed. However, the abdominal hernias recurred 16 months later. The continual egg-laying probably predisposed this bird to hernia formation. Abdominal hernias in birds may be a consequence of continual egg-laying and associated hormonal effects leading to a weakening of abdominal musculature.  相似文献

A not pregnant 4-year-old Jersey cow was presented with the sudden appearance of respiratory noise, nasal discharge and moderate respiratory difficulty. Upon physical examination a snoring-like noise, extended head and neck position, exaggerated abdominal effort, bilateral nasal discharge and left prescapular lymph node enlargement were noted. Sub-occlusion of the initial portion of the respiratory tract was suspected. Radiographic and endoscopic examinations revealed a pedunculate mass on the dorsal aspect of the rhinopharynx, which was removed with endoscopically assisted electrosurgery. Histologic examination revealed a chronic pyogranulomatous inflammation with eosinophilic club-like bodies surrounding small colonies of rod-shaped bacteria. Results of histochemical staining were consistent with Actinobacillus-like bacteria and a diagnosis of respiratory actinobacillosis was reached. Surgery and antibiotic therapy were resolutive, as demonstated by an endoscopic check at the second month after surgery, even without the association of the traditional iodine cure, which is regarded as the treatment of choice for actinobacillosis.  相似文献
