A 5.5-year-old Siamese presented for evaluation of a three-day history of anorexia and lethargy. Upon physical examination, the cat was depressed, dehydrated, pyrexic, had injected conjunctiva and sclera, pale mucous membranes, and a grade II/VI systolic heart murmur. Thoracic radiographs revealed moderate to severe, diffuse, bronchointerstitial pulmonary changes with enlarged and tortuous pulmonary vessels. With continued hospitalization, the cat became dyspneic and died. The postmortem cytopathological examination of the liver, spleen, and lung impressions revealed reticuloendothelial cell infection with Cytauxzoon felis. 相似文献

This paper describes a mycetoma of the fourth tarsal bone of a 5-year-old spayed Corgi-cross bitch caused by the eumycete Curvularia geniculata. The condition was treated successfully by surgical excision, followed by chemotherapy using iodine, trimethoprim-sulphadiazine, amphotericin B. dimethyl sulphoxide. thiabendazole and nystatin. An attempt was made to establish the in vitro minimum inhibitory concentration of various antifungal drugs on the causative organism. No clinical or radiological evidence of recurrence was found 3 years after initiation of treatment, despite the original poor prognosis. 相似文献

A 10-month-old, neutered male Saint Bernard presented for evaluation of acute, severe vomiting. A soft-tissue mass was noted within the stomach on survey abdominal radiographs. The diagnosis of pylorogastric intussusception was made during exploratory celiotomy. The intussusception was manually reduced at surgery, the pyloric antrum was enlarged, and the duodenum was permanently affixed to the abdominal wall in an attempt to prevent recurrence of the intussusception. The dog recovered, has gained weight (5 kg), and has had only one isolated episode of vomiting during the one year since discharge from the hospital. This report documents the fourth reported case of pylorogastric (i.e., duodenogastric, gastrogastric) intussusception in the veterinary literature and is the first report that details the surgical management of the disease. 相似文献

A 7-y-old, intact male Alaskan Malamute was presented with a 3-mo history of stertor and epistaxis. Computed tomography of the skull revealed generalized loss of gas throughout both nasal passages with replacement by a soft tissue mass that traversed the cribriform plate. Histopathology revealed neoplastic neuroblast cells arranged in anastomosing cords, as well as separately located aggregates of ganglion cells. Both neoplastic cell populations demonstrated immunoreactivity to MAP-2, TuJ-1, and synaptophysin. Neuroblastic cells additionally exhibited punctate immunoreactivity to MCK and CK8/18. We document here both the positive neural immunohistochemical markers for this neoplasm, as well as propose possible histomorphologic variants. 相似文献

Q fever is a worldwide zoonosis caused by Coxiella burnetii. The clinical manifestations of Q fever include endocarditis, pneumonitis and hepatitis. Disease awareness and evolving diagnostic tests have enabled the recognition of unusual manifestations of Q fever. We report a case of Q fever osteomyelitis. A 51-year-old patient was admitted to hospital because of fever, leg weakness, and asthenia. His past medical history included surgery and a bone graft for the treatment of a giant cell tumor on the distal part of the femur. Blood and bone biopsy cultures were negative. Bone histological examination was consistent with a sub-acute or chronic inflammatory reaction that involved foci of epithelioid and gigantocellular infiltrates and necrosis. Serology testing revealed high antibody titers to C. burnetii antigens (phase I: IgG 3200; IgA 200; phase II: IgG 6400; IgA 400), which is indicative of chronic Q fever. The specific Polymerase Chain Reaction (PCR) of the abscess sample from the femoral region was positive for C. burnetii. The patient was treated for chronic Q fever with doxycycline and hydroxychloroquine for 18 months and recovered gradually without recurrence of pain or functional impairment. Q fever osteomyelitis is a rare and most likely underestimated disease. Epithelioid and gigantocellular granulomatous osteomyelitis in the context of culture-negative bone specimens should raise suspicion of Q fever. Serological tests, specific PCR and cell culture can provide evidence of a C. burnetii infection. Although bone diffusion may be a concern, the currently recommended treatment for Q fever was effective in this case. 相似文献

Mares regularly have an enlarged ovary. The main causes are haematomas, anovulatory follicles, abscesses, and neoplasia. The granulosa-theca-cell tumour is by far the most common neoplasia of the ovary (about 97%) and accounts for 2.5% of all equine tumours. In this article the differential diagnosis of an enlarged ovary and the background of granulosa-theca cell tumours are reviewed. A case is described of a mare with a very large granulosa-theca cell tumour in the left ovary, which was discovered 1 month after delivery of a healthy foal. This case is special not only because the tumour was enormous (diameter 60 cm) but also because the contralateral ovary was functional and there were no behavioural changes. The fact that a haematoma had been found 2 years earlier made the diagnosis even more difficult. 相似文献

A nine-week-old Clydesdale foal was presented with severe anemia, panleucopenia and thrombocytopenia. Bone marrow biopsy revealed marrow fat and bone spicules but was almost acellular, indicating the existence of aplastic anemia. Histological examination of marrow obtained at post mortem examination revealed only occasional nests of mononuclear cells. Marked biliary hyperplasia was present in the liver. The etiology was uncertain but a toxic insult resulting in aplastic anemia and hepatic disease may have occurred in utero or in the neonatal period. This appears to be the first report of aplastic anemia in a foal. 相似文献

CASE HISTORY: A 2-year-old Standardbred gelding presented with a history of fever over 1 week, anorexia and skin lesions on all four legs. The lesions were associated with severe pruritus and oedema, and there was no response to therapy. CLINICAL FINDINGS: The horse was in poor body condition, was lethargic and severely pruritic. Skin lesions consisted of diffuse alopecia and crusting of the distal extremities. Initially it was slightly febrile, but subsequently its temperature increased up to 40°C. Ten days after admission it developed profuse watery diarrhoea and the skin lesions progressed. Skin biopsies revealed superficial and deep perivascular dermatitis with lymphoplasmacytic and eosinophilic predominance. Based on the poor prognosis the horse was subject to euthanasia. PATHOLOGICAL FINDINGS: The most notable lesions included ulcerative gastritis, typhlitis and colitis with prominent oedema of the intestines, marked subcutaneous oedema and severe thickening of the large bile ducts. Histopathology showed marked eosinophilic and lymphoplasmacytic infiltration of various tissues including the skin, gastrointestinal tract, mesenteric lymph nodes, large bile ducts, pancreatic duct and kidney. Immunohistochemistry revealed a clear predominance of CD3-positive cells in the lymphocytic infiltrations. DIAGNOSIS: Based on the clinical findings and histopathology a diagnosis of multisystemic eosinophilic epitheliotropic disease (MEED) was made. CLINICAL RELEVANCE: Multisystemic eosinophilic epitheliotropic disease is rare in horses, and usually chronic. In the current case the horse showed an apparently acute onset with high fever and rapid clinical deterioration. A diagnosis of MEED should be considered in horses presenting with weight loss and skin lesions with or without fever. A final diagnosis is based on histological results of biopsy specimens from affected organs. 相似文献

A case of hypervitaminosis A with secondary entrapment and compression of the left brachial plexus nerve roots is described. A 9-year-old male castrated domestic shorthair, fed a home-made diet based on raw pork liver, was submitted for examination for a left forelimb lameness that evolved to paralysis over a 2-month period. Clinical examination revealed a flaccid paralysis and atrophy of all left forelimb muscles. An ipsilateral Horner's syndrome was also noted. Radiological examination of the cervical and thoracic spine showed massive new bone formation at the ventral aspect of the second cervical to sixth thoracic vertebra. The diagnosis of hypervitaminosis A was made, based on the clinical and radiographic findings, as well as the determination of serum vitamin A concentration, which was 630 microg/dl, three times above the upper normal limit for this species. Despite the unfavourable initial prognosis, the cat progressively regained function of the affected limb approximately 6 months after the diet was changed to a commercial canned food. 相似文献

A four-year-old, spayed female Yorkshire terrier was presented with a two-month history of lameness in the left forelimb, circling and falling. A magnetic resonance imaging (MRI) examination 11 days after presentation revealed dilation of the right lateral ventricle. Following euthanasia, which was performed about 10 months after the onset of clinical signs, there was gross evidence of degeneration and cavitation of the cerebrum and dilation of the lateral ventricle on the right side. Microscopically, cavitation and necrosis were observed in the white and grey matter of the right cerebrum and there was abundant gemistocytic and fibrillary astrocytosis. Haemorrhage and marked perivascular cuffing with mononuclear cells were found in the mesencephalon. Inflammatory lesions consisting of lymphocytic infiltration and glial proliferation were also present in the dorsal funiculus of the cervical spinal cord. This case was diagnosed as necrotising encephalitis in the Yorkshire terrier (NEYT) with involvement of the spinal cord. NEYT is a chronic progressive neurological disorder, resulting from widespread, destructive non-suppurative inflammation of the central nervous system of unknown cause. In the past decade, 12 cases have been documented in adult to aged Yorkshire terriers. Computed tomography and MRI can detect the characteristic multifocal cavitations and ventriculomegaly, facilitating premortem diagnosis. 相似文献

The first known report of synovial fluid eosinophilia in a dog is described here. The occurrence of eosinophils in joint fluid is rare. Sporadic cases have been recorded in humans and most can be related to immunemediated reactions, both parasitic and non- parasitic. The dog in this case report had 20-52% eosinophils in multiple joints, as well as hemarthrosis and marked mononuclear cell reactivity. An intense peripheral eosinophilia was demonstrated one week later. The associated lameness resolved with non-steroidal anti-inflammatory therapy. Lack of remarkable history or other clinical symptoms led to a diagnosis of idiopathic, eosinophilic, polyarthritis, likely immune-mediated. 相似文献

Congenital defects like myofibrillar dysplasia (splayleg), umbilical and inguinal hernias, cryptorchism, intersexes, and anal atresia occur relatively frequently in swine. On the other hand, some developmental anomalies like double monsters are very rare. The present paper reports a rare case of a congenital complex malformation including polymelia, duplicitas coli partialis et recti, atresia ani et fistula rectogenitalis, duplicitas corpori uteri, cervicis, vaginae et vulvae and duplicitas vesicae, urethrae et renalis. A plausible interpretation concerning the etiology is that the anomalies arose from unequal partial twinning. The pig has been healthy and inconspicuous. Although no anus was formed defecation took place via a fistula to one of the vaginas. Posture and behaviour of the pig were normal. Cytogenetic analysis of blood lymphocytes revealed no numerical or gross structural anomalies. There have been no further piglets with developmental disorders in the same litter, in a second litter of the same parents and in other twelve litters by the same boar. 相似文献
