A 0.9 kg lipoma was removed surgically from the cranial mediastinum of an 11-year-old dog. Clinical signs related to the mass consisted of coughing and dyspnea. Postoperative recovery was uncomplicated and the clinical signs diminished immediately. The thoracic cavity is an unusual location for the development of a lipoma. 相似文献

An eight‐year‐old, neutered, male German short‐haired pointer was presented for a chronic cough and an intrathoracic mass. Computed tomography revealed a mass with low attenuation in the right caudal lung lobe that invaded the principal bronchi. The mass was removed by right caudal and accessory lung lobectomy. The histopathological diagnosis was pulmonary lipoma. The clinical signs resolved following surgery. There was no evidence of recurrence or de novo lesions on computed tomography performed 12 months post‐surgery. To the authors’ knowledge, this is the first report of a pulmonary lipoma in a dog. 相似文献

A 10 yr old female cat presented for an acute onset of back arching, regurgitation, and open mouth breathing. Radiographs indicated the presence of a large intrathoracic mass. Computed tomography confirmed the presence of a large mass of fatty density in the dorso-caudal mediastinum. The mass was removed via right intercostal thoracotomy, and histopathology confirmed the mass as a lipoma. The cat was continuing to recover well as of 21 mo after surgery. This is the first reported case of an intrathoracic lipoma in a cat. 相似文献

Histologically confirmed lipomas were surgically removed from the thoracic or abdominal cavities of six dogs. Three dogs had a large intra-abdominal mass causing severe abdominal distension. Two dogs had a mass extending into the pelvic canal, compressing the colon and causing obstipation. One dog with an intrathoracic mass had a history of coughing and intermittent cyanosis. All dogs had complete resolution of signs after surgical resection of the tumour. Recurrence occurred in one dog with an abdominal lipoma, two years after the initial surgery. This recurrent lipoma was treated successfully by surgical resection. 相似文献

An intrathoracic mass was discovered as an incidental finding in a 14-year-old, spayed, female Rottweiler cross during evaluation of urinary incontinence. Computed tomography suggested a pericardial or pleural location and high adipose content of the mass. The mass was removed via lateral thoracotomy with partial pericardectomy and was diagnosed as a pericardial lipoma. The dog recovered well, and there was no evidence of recurrence approximately one year later. Adipose tumours of the heart and its associated structures are rare in dogs and have been associated with both successful and fatal outcomes. 相似文献

An 8-year-old spayed Scottish Terrier was examined because of a history of intermittent abnormal behavior that progressed to hind limb ataxia and eventually to recumbency with opisthotonos. X-Ray computed tomography revealed a radiolucent mass in the area of the hypothalamus. At necropsy, a suprasellar cystic papillary meni-ngioma was identified. The unusual clinical signs of disease and computed tomographic findings of this case complicated diagnosis. 相似文献

A 20-year-old gelding Lipizzaner horse was referred for onset of profuse sweating and increased heat on the right side of the head, neck, and thoracic limb. On physical examination, the horse presented tachycardia, muffled heart sounds with a pansystolic murmur, and signs of heart failure such as ventral edema, jugular distention, and pulsation. Ultrasonography examination revealed a bilateral pleural effusion and a large intrathoracic mass extending into the anterior mediastinum, which shifted the heart dorsocaudally. Thoracocentesis revealed serosanguineous fluid indicative of a melanocytic tumor. Thoracoscopy revealed a large dark mass extending into and filling the cranioventral mediastinum. The mass appearance was consistent with a melanoma, and because prognosis was poor, the owner elected euthanasia. A necropsy supported the presence of disseminated melanomas with a greater thoracic mass involving the right cervicothoracic ganglion, leading to clinical signs of sympathetic denervation. 相似文献

The clinical and pathologic findings related to an infiltrative facial lipoma in a 5-month-old female Holstein Friesian calf are reported. The tumor was congenital, increased in size with time, and deformed the left side of the face and cranial bones. The clinical condition of the calf was good; the only detectable abnormalities were poor weight gain and decreased motility of the left upper lip. Clinical and radiologic data indicated the mass was not removable. Muscle and lymph node invasion by tumor tissue were detected histologically. Infiltrative lipoma is a rare variety of lipoma that has been reported in dogs, cats, horses, and humans. Although its cytologic characteristics are those of a benign tumor, in this patient the invasiveness of the neoplasm was associated with poor prognosis. 相似文献

Congestive heart failure is a common presentation in small animal practice. Cardiac tumours are an unusual cause of congestive heart failure and, when they occur, usually cause clinical signs associated with pericardial effusion and cardiac tamponade. This case report outlines the clinical and histological findings in two dogs presented with clinical signs of congestive heart failure caused by obstruction of blood flow by intracavitary cardiac tumours. Case 1 showed signs of left-sided heart failure caused by osteosarcoma within the left atrial lumen, and case 2 presented with clinical signs of right-sided heart failure due to haemangiosarcoma occupying the right atrial and ventricular lumens. This case report provides further evidence for the inclusion of intracardiac neoplasia in the differential diagnosis for dogs with clinical signs of congestive heart failure. 相似文献

Idiopathic muscular hypertrophy of the oesophagus (IMHO) is reported in equids as an incidental post mortem finding, infrequently associated with clinical signs of oesophageal dysfunction or additional oesophageal abnormalities. Clinicopathological and post mortem findings are presented from a 15‐year‐old gelding that developed a spontaneous perforation of the distal, intrathoracic oesophagus, in association with IMHO. The majority of oesophageal perforations documented in the equine literature have been related to external or iatrogenic trauma resulting in rupture of the cervical portion of the oesophagus. In this case, the early presenting features included pyrexia and inappetance, and progressed over a 4 day period to include signs of tachypnoea, tachycardia and endotoxaemia due to the development of a fatal septic pleuritis and pleural effusion. Oesophageal obstruction was not a presenting feature. Diagnostic investigation in cases of unexplained septic pleural effusion should include oesophageal endoscopic evaluation to rule out perforation of the intrathoracic oesophagus. IMHO may represent a clinically significant, primary disease entity with the potential to lead to oesophageal perforation. 相似文献

Objective— To describe an unusual long-term complication of circular end-to-end anastomosis (CEEA) stapling in a dog.
Study Design— Clinical case report.
Animal— An 11-year-old, female neutered, Labrador Retriever.
Methods— The dog was referred for clinical signs of bowel obstruction. An enterectomy was performed 2 years before presentation using a CEEA stapling device. Palpation, plain radiographs, and ultrasound of the abdomen confirmed the presence of a mass in the bowel, causing obstruction, and requiring surgical approach.
Results— An exploratory celiotomy revealed a 5 cm mass in the jejunum, involving the site of the previous surgery. The mass was removed by enterectomy. Dissection of the mass revealed the presence of many staples at the previous enterectomy site, and a trichobezoar entangled in the exposed parts of the staples.
Conclusions— An enterectomy was required to treat an intestinal obstruction caused by a trichobezoar entangled in a CEEA-stapled anastomosis.
Clinical Relevance— Development of trichobezoar and subsequent bowel obstruction should be considered an unusual but potential long-term complication of CEEA-stapled anastomosis. 相似文献

Retropharyngeal infections in horses normally induce local painful swelling of the retropharyngeal area, which may lead to dyspnea, dysphagia, and systemic manifestations. Differential diagnosis of local painful swelling of the retropharyngeal area includes retropharyngeal lymph node infection, neoplasm, cellulitis, hematoma, guttural pouch empyema, parotiditis, and jugular thrombosis. Apart from Streptococcus equi ssp. equi, other bacteria are rarely reported as a cause of retropharyngeal abscesses. The reason for this might be a lack of specific sampling to identify the causative agent. This work deals with a case of retropharyngeal infection in an 11-year-old Standardbred stallion with acute depression, fever, tachycardia, asymmetric painful swelling in the throat area, ptyalism, and respiratory distress. Endoscopy, radiography, ultrasonography, blood analysis, and cytological examination of a puncture sample taken from the throat mass were consistent with a pyogenic to pyogranulomatous retropharyngeal inflammation. The clinical evolution was initially satisfactory in response to treatment with nonsteroidal anti-inflammatory drugs and antibiotics, but clinical signs relapsed twice, each time a few weeks after cessation of antibiotic therapy. The bacteriologic finding in this case was unusual and consisted of the isolation of a Pasteurella multocida strain that was obtained after the second relapse (ie, 79 days after initial admission), using a brain heart infusion (BHI) medium, and after two successive negative bacteriological cultures performed on day one of clinical signs and at the first relapse of clinical signs, respectively. 相似文献

A 19-week-old, entire female boxer dog was presented for evaluation of chronic, progressive multi-focal neurological signs. Magnetic resonance imaging suggested a large intra-axial mass in the brainstem. Euthanasia was performed and an anaplastic astrocytoma was found at post-mortem examination. This case reports an unusual naturally occurring brain tumour in a young dog. 相似文献

Hepatic myelolipoma incarcerated in a peritoneopericardial diaphragmatic hernia was diagnosed in an 11-year-old, desexed female Persian cat. The cat was initially referred for investigation of tachypnoea and dyspnoea. Peritoneopericardial diaphragmatic hernia is a common incidental finding in cats and is usually asymptomatic. Myelolipoma is an extremely rare benign tumour, composed of extramedullary haematopoietic cells and adipose tissue. Myelolipomas are hypothesised to result from metaplastic alteration, rather than a neoplastic process, although this theory cannot be substantiated. The present case is only the fourth report of such an unusual occurrence in cats and displays significant differences to previous reports. Hepatic entrapment and burgeoning of the mass within the pericardial sac resulted in cardiac tamponade and overt signs of right-sided cardiac failure. Surgical intervention was successful and despite concerns regarding the cat's clinical presentation and the gross appearance of the lesion(s), a good long-term outcome is anticipated. 相似文献

An unusual form of strangulation of mesentery only by pedunculated lipoma was identified as the cause of moderate to severe colic in four horses. The small intestinal mesentery was involved in three horses and the small colon mesentery in the fourth horse, but the associated intestine was not strangulated, haemorrhagic, nor obviously obstructed in any horse. In all horses, a patch of haemorrhagic mesentery of variable size was evident around the origin of a mesenteric lipoma and a major mesenteric vessel. One horse was subjected to euthanasia at the owner's request and the remaining three had surgery from which they made a complete recovery after the removal of the lipoma. Intestinal resection was not performed in any of the three horses undergoing surgery. An isolated mesenteric strangulation by lipoma is an uncommon cause of colic in older horses that have the typical presentation of a strangulating lipoma. The removal of the involved lipoma without mesenteric or intestinal resection can be associated with complete recovery. 相似文献

A seven-year-old, entire female boxer presented with a history of restless behaviour and inappetence. Physical examination revealed that the dog was listless and had a hunched gait. Neurological examination was normal. Abdominal ultrasonography revealed a 4 cm x 4 cm mass in the cranial pelvic canal. Neurological abnormalities were detected three days after presentation, and progressed from proprioceptive deficits to loss of deep pain sensation in the pelvic limbs over a two-day period. The dog was euthanased and postmortem examination revealed that the pelvic mass was a urethral haemangiosarcoma with metastasis to the second lumbar vertebra. This case is unusual as urethral tumours are usually transitional cell carcinomas and frequently present with signs of dysuria. 相似文献

The surgical repair of complete intrathoracic tracheal avulsion in three cats is described. The initial presenting signs included dyspnoea, exercise intolerance and exertional cyanosis. Diagnosis was based upon the clinical signs, survey radiography and tracheal endoscopy. The ruptures were repaired via a right lateral thoracotomy made at the third or fourth intercostal interspace. Abnormal trachea was resected and a standard tracheal anastomosis was performed. Surgical results were considered excellent in all cases. 相似文献

OBJECTIVE: To describe three cases of canine thoracic actinomycosis (arcanobacteriosis) or nocardiosis in which the primary pathological lesion was a pyogranulomatous abscess in the mediastinum. Clinical signs, difficulties in diagnosis, treatment and prognosis are examined. Comparisons are made between human and veterinary literature to assist in formulating a rational treatment plan. DESIGN: Retrospective clinical study. PROCEDURE: Review of case records from 1984 to 1998. RESULTS: Three dogs presented with large intrathoracic pyogranulomas producing variable clinical signs, not necessarily associated with the respiratory tract. Ages ranged from 2 to 5 years old. Two dogs responded to surgical opening and passive drainage of the abscess, or surgical excision of the granuloma with associated structures, and medical therapy. One dog died intra-operatively. CONCLUSION: A combination of surgical and antimicrobial therapy may carry a fair-to-good prognosis for thoracic granuloma caused by actinomycosis (arcanobacteriosis) or nocardiosis. The extent of surgery should be based on assessment of individual cases and must include surgical biopsy for histology and culture to enable a specific diagnosis to be made. Complete surgical excision is not necessarily required. Prolonged antimicrobial therapy is indicated. 相似文献

An unusual congenital portosystemic shunt was identified in one dog and two cats with clinical signs and laboratory evidence of hepatic dysfunction. In all the animals, the abnormal vessel arose from the portal system between the left medial and quadrate liver lobes and travelled within the falciform fat, exiting the abdomen through the caudal ventral left diaphragm. The intrathoracic course of these vessels was not established. The anatomical location of this anomalous vessel may have hindered attempts at ultrasonographic identification since it was not visualised before surgery in any of the animals. In addition, while the anatomical location of the vessel may facilitate rapid identification and surgical attenuation, it could predispose the vessel to trauma during the coeliotomy approach. It is hypothesised that this form of portosystemic communication results from failure of a portion of the left umbilical vein to degenerate during embryogenesis. This is in contrast to other forms of congenital extrahepatic portosystemic shunt that are presumed to be developmental errors resulting in an abnormal communication between the embryonic vitelline and cardinal venous systems. The prognosis for animals with the vascular anomaly reported here is probably similar to that for animals with other forms of congenital portosystemic shunt. 相似文献
