A 5-year-old dog developed neurologic signs of thoracolumbar spinal cord dysfunction. The presence of an epidural mass which affected the electromyogram of the T-13 to L-3 spinal segments was demonstrated by myelography. Surgical removal was attempted. Examination of frozen and formalin-fixed tissues revealed the mass to be a chondrosarcoma. Doxorubicin hydrochloride was given every third week for a total of 6 doses following surgery. No signs of recurrence or metastases have been found for over 6 months. The differential diagnosis of epidural masses should include chondrosarcoma, even in the absence of vertebral lesions on plain radiographs, as in this case. Rapid diagnosis and aggressive therapy may have improved the prognosis. 相似文献

From a two-year review of diagnostic two-dimensional real-time echocardiographic studies, a diagnosis of cardiac mass lesion was made in 18 dogs. Thirteen of 18 also had pericardial effusion. Three types of lesions were identified: (1) right atrial masses (7 dogs; 5 confirmed as hemangiosarcoma) originating from the wall of the right atrium of right auricle and projecting into the atrial lumen, pericardial space, or both; (2) large cavitary pericardial masses (2 dogs; both confirmed as abscesses) located over the right ventricle; (3) heartbase masses (9 dogs; 6 confirmed as neoplasms) attached to the ascending aorta, with varying degrees of infiltration of heartbase structures. Although extrapericardial portions of the masses were not outlined as well as intrapericardial portions, surgical accessibility was correctly predicted in most dogs. It was concluded that two-dimensional echocardiography (2DE), performed systematically using multiple imaging planes, allowed accurate detection and localization of cardiac and pericardial masses in dogs and was useful in predicting surgical accessibility of these lesions. 相似文献

A 10-year-old female Dachshund was presented with a history of mammary masses, slight lethargy, polyuria, and polydipsia. Physical examination findings included masses involving the first, second, and fourth mammary glands of the left side. The mandibular, axillary, and right popliteal lymph nodes were mildly enlarged. Serum chemistry results included hypercalcemia (13.9 mg/dL, reference interval 8.0-11.5 mg/dL). Although intact parathyroid hormone (PTH) concentration (1.05 pmol/L) was below the reference interval (2-13 pmol/L), PTH-related protein (PTHrP) concentration was markedly increased (9.40 pmol/L, reference value < 2 pmol/L). The masses were surgically removed, and the histopathologic diagnosis was complex mammary carcinoma. Three weeks after surgery, serum total calcium concentration had decreased to 10.5 mg/dL. Resolution of the hypercalcemia and clinical signs supported a diagnosis of humoral hypercalcemia of malignancy associated with mammary gland carcinoma. 相似文献

Osteochondrosis of the lateral femoral condyles was diagnosed radiographically in an 8-month-old, female Arabian horse, which had been presented with a hindlimb lameness. The diagnosis was confirmed by gross and microscopic pathology. The location of the lesions was considered unusual for osteochondrosis in the horse. 相似文献

Traumatic hypopituitarism was diagnosed in an 11-month-old male neutered cat. The presenting complaints were polydipsia, polyuria and lethargy of three months' duration. Craniocerebral trauma, as a result of a road traffic accident, had preceded the onset of clinical signs by six weeks. Neurological examination revealed right-sided mydriasis, reduced visual and tactile left forelimb placing reflexes and decreased proprioception in both the left fore- and hindlimb. Initial laboratory findings included hypernatraemia, hyperchloraemia, mild azotaemia, eosinophilia and isosthenuria. Low basal cortisol, thyroxine, thyroid-stimulating hormone and insulin growth factor-1 were noted. Subsequent to treatment with prednisolone, a water deprivation test confirmed the presence of central diabetes insipidus and therapy with synthetic antidiuretic hormone successfully ameliorated the polydipsia. 相似文献

Extraskeletal myxoid chondrosarcoma was found in a five-month-old male Irish setter dog. At necropsy, the largest mass, measuring 15 × 13 × 13 cm, was found in the right caudal lobe of the lung, and metastatic small masses were observed in multiple organs. Microscopically, the tumor comprised mainly atypical mesenchymal cells and myxoid stroma, which stained positively with Alcian blue. Immunohistochemically, the tumor cells stained positively for vimentin, S-100 protein, neuron-specific enolase, calretinin, and chromogranin A. Ultrastructurally, the cytoplasm of the tumor cells was comprised abundant rough endoplasmic reticulum, mitochondria, Golgi complex, free ribosomes and short irregular microvillous processes extending from the cytoplasm. Based on these pathological findings, this tumor was diagnosed as extraskeletal myxoid chondrosarcoma. 相似文献

Multidetector‐row computed tomographic contrast angiography (MDCTA) is routinely employed to investigate vascular masses in human patients but, to date, the use of this technique to investigate an aneurysmal mass has not been reported in an equine case. The potential of MDCTA to investigate a right‐sided parapharyngeal mass in a 6‐week‐old Thoroughbred foal was therefore investigated. A 4‐slice helical computed tomography scanner was used on a superficial, firm, ovoid mass yielding arterial blood on fine needle aspiration. MDCTA enabled identification of the vessels involved thus assisting in forming a diagnosis based on the morphology of the lesion and aided surgical planning. Histology confirmed the presence of mural thrombus and calcification within the smooth muscle wall consistent with a true aneurysm. MDCTA provided additional information to conventional imaging in this case of vascular masses of the head and neck. The technique therefore has the potential to improve diagnosis and assist in the management of such lesions. 相似文献

A 1-year-old neutered male domestic shorthair cat presented with a 4-week history of polydipsia that began immediately after an 8 metre fall. Trauma-induced central diabetes insipidus was suspected on the basis of the identification of hyposthenuria, normal haematology and serum biochemistry profile and unremarkable abdominal ultrasound examination. Failure to concentrate urine with water deprivation followed by production of hypersthenuric urine with administration of the synthetic antidiuretic hormone, Deamino-8-D-arginine vasopressin (DDAVP), confirmed the diagnosis of central diabetes insipidus. Treatment via conjunctival administration of DDAVP failed to attenuate the polydipsia, however, resolution of polydipsia was achieved with subcutaneous administration of DDAVP and the cat remains eudipsic with twice daily subcutaneous DDAVP administration 17 months after diagnosis. 相似文献

A captive adult male Eastern barred bandicoot (Perameles gunnii) presented with three palpable subcutaneous masses in November 1998. A diagnosis of haemangiosarcoma was made based on histological examination of one excised mass. Euthanasia of the animal was performed 11 days postsurgery and a proliferative lesion in the paralumbar musculature and similar, smaller proliferative lesions surrounding the right popliteal lymph node and in the ventricular wall of the heart were found. Metastatic lesions were found in the liver and lung. The histological features of the neoplastic tissues supported the diagnosis of a poorly differentiated, disseminated haemangiosarcoma. This is the first reported case of haemangiosarcoma in the Eastern barred bandicoot. 相似文献

A 4-year-old cat was presented for polyuria and polydipsia. Unilateral hydronephorosis and hydroureter was diagnosed on ultrasound examination of the abdomen, and right ureteral calculi were seen in survey abdominal radiographs. Intravenous urography confirmed hydronephrosis and indicated poor renal funttion in the right kidney. Surgical removal of the ureteral calculus improved right renal function. Analysis of the calculus indicated composition of calcium oxalate, an uncommon calculus in cats. 相似文献

A 2-year-old quarter horse gelding presented for evaluation of polyuria and polydipsia. Azotemia was detected on serum chemistry profile. Small, misshapen, hyperechoic kidneys with decreased corticomedullary demarcation, hydronephrosis, and a right nephrolith were noted ultrasonographically. The diagnosis of end-stage kidney disease and dysplasia was made histopathologically using ultrasound-guided biopsy. Two ureteroliths were found in the right ureter via cystoscopy, and a nephrolith was seen in the right kidney at necropsy. Clinical, ultrasonographic, and pathologic features of equine urolithiasis and renal dysplasia are discussed. 相似文献

This report describes the detection of subclinical soft tissue metastasis of an appendicular osteosarcoma in a dog using bone scintigraphy. A 7-year-old spayed female Rottweiler was presented with a biopsy confirmed diagnosis of osteosarcoma. Initial radiographs revealed an aggressive bone lesion of the left distal radius. At presentation, there was no clinical or radiographic evidence of metastasis; however, a nuclear bone scan showed the primary bone lesion of the distal left radius and numerous soft tissue lesions consistent with diffuse soft tissue metastases. A left foreleg amputation was performed and cisplatin chemotherapy was given post-operatively. A second bone scan performed one month following initial presentation showed progression in size and number of soft tissue masses. Many of the lesions had become apparent on physical exam and survey radiographs. Excisional biopsy was performed on one of the soft tissue masses and a diagnosis of metastatic osteosarcoma was made. The dog was euthanized 2 months after initial presentation at the owners request due to deterioration of the animals physical condition. 相似文献

The case records of and histopathologic findings in 57 dogs with nonangiogenic and nonlymphomatous splenic sarcomas were reviewed. Splenic neoplasms in these dogs included leiomyosarcoma, fibrosarcoma, undifferentiated sarcoma, liposarcoma, osteosarcoma, chondrosarcoma, myxosarcoma, rhabdomyosarcoma, and fibrous histiocytoma. The clinical signs associated with splenic sarcoma included anorexia or decreased appetite, abdominal distention, polydipsia, lethargy, vomiting, weight loss, and weakness. An abdominal mass was detected in 86% of the dogs by use of abdominal palpation (63%), and/or abdominal radiography (74%). The diagnosis was based on histopathologic findings in the spleen. Abdominal exploratory surgery was performed on 43 of the 57 dogs. Twenty-seven dogs were treated by splenectomy, and 16 were euthanatized at the time of surgery because of widespread metastatic lesions. Of the 14 dogs on which surgery was not performed, 11 were euthanatized on the basis of results of preoperative diagnostic tests, and the remaining 3 dogs had splenic neoplasms that were incidental findings at necropsy. Of the 27 surgically treated dogs, 5 died in the immediate postoperative period, 12 died or were euthanatized within 1 year after splenectomy, and only 5 dogs survived greater than or equal to 1 year. Three dogs were lost to follow-up evaluation, and 2 were still alive 6 and 7 months after surgery. The median survival time of the 22 dogs for which survival was known was 2.5 months. The median survival time for 11 dogs with no obvious metastasis at the time of splenectomy was 9 months.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

This paper describes four cats with hyperadrenocorticism. Cat 1 showed polydipsia and polyphagia. Diabetes mellitus was initially diagnosed. As the animal appeared to be insulin resistant, pituitary and adrenocortical function tests were performed and the diagnosis of hyperadrenocorticism was made. Resistance to the high-dose dexamethasone suppression test was noticed in this cat. Pathological examination revealed a pituitary chromophobe adenoma. Cat 2 presented with diabetes mellitus, which was treated with insulin. The animal had a pendulous abdomen and its coat was in a poor condition. The low-dose dexamethasone suppression test demonstrated hyperadrenocorticism. Necropsy findings of pituitary tumour and hyperplasia of the adrenal cortex confirmed the diagnosis. Cat 3 showed clinical abnormalities indicative of hyperadrenocorticism, for instance, muscle weakness, alopecia, multiple abscesses. The diagnosis of hyperadrenocorticism was confirmed by the results of the lowe-dose dexamethasone suppression test. Pathological examination revealed an adrenocortical carcinoma. Cat 4 presented with polydipsia. The cause of this symptom was not found initially. One and a half years later additional symptoms, such as nephritis and polyphagia developed. Hyperadrenocorticism was diagnosed because of a palpable mass cranial to the left kidney. The diagnosis was confirmed by the results of the lowe-dose dexamethasone suppression test and the necropsy findings. 相似文献

A 10-year-old spayed female Golden Retriever was referred for hindlimb lameness. A firm mass was palpated over the right caudal pelvis. Computed tomography revealed an osteolytic bone region and an associated periosteal reaction in the ischium, including the acetabulum. The histological diagnosis was sarcoma of unknown origin. A mid-to-caudal partial hemipelvectomy was performed to remove the mass. Femoral head and neck osteotomy was performed to allow hindlimb preservation. Following surgery, the dog regained satisfactory hindlimb use over time and was alive for 821 days with no recurrence or metastatic disease. This report indicates that mid-to-caudal partial hemipelvectomy with femoral head and neck osteotomy is technically feasible and allows for tumor control with preservation of the hindlimb and its function. 相似文献

A 19-year-old Thoroughbred gelding presented with sudden onset, non-weight bearing lameness in the right hindlimb. Radiography confirmed distal luxation of the patella, which was replaced into its normal anatomical location under general anaesthesia. There were no pathological sequelae noted on follow-up examination 9 months after the initial injury. To our knowledge, this is a rare manifestation of patellar luxation, only reported once previously in the equine literature. 相似文献

A four-year-old, male neutered domestic shorthaired cat was presented with a two-week history of nasal and ocular discharge, generalised exfoliative dermatitis, intense pruritus, polydipsia, polyphagia, weight loss, intermittent hindlimb ataxia and lethargy. Cutaneous populations of Malassezia pachydermatis yeast organisms were found to be elevated. The generalised nature of the disease prompted survey radiography which revealed the presence of a cranial mediastinal mass which was subsequently resected and found to be a thymoma. Within six months of surgery, systemic and cutaneous signs had resolved and yeast counts had returned to normal, suggesting a causal relationship between the thymoma and the skin disease. 相似文献
