A 10-year-old neutered female cat had chylothorax, precaval syndrome, and a mediastinal granuloma resulting from infection with Cryptococcus neoformans. Diagnosis of a chylous effusion was made by cytologic examination of pleural fluid and by finding higher triglyceride levels in the effusion than in serum (825 vs. 64 mg/dl, respectively). Postmortem examination revealed cryptococcal organisms in the mediastinal granuloma, lungs, cerebral meninges, and connective tissues adjacent to the thyroid gland. Chylous effusion in a cat associated with cryptococcosis has not been reported previously. Cryptococcosis should be included in the differential diagnosis in chylous effusions in cats. 相似文献

Naturally occurring cryptococcosis in five cats, a dog and a koala is described. Involvement of the nasopharynx was documented in all patients, and nasopharyngeal mass lesions accounted for the major presenting complaints in four. Signs referable to nasopharyngeal disease included snoring, stertor, inspiratory dyspnoea and aerophagia. Diagnoses were made by caudal rhinoscopy using a retroverted flexible endoscope, vigorous orthograde flushing with saline, or at necropsy. Concurrent cryptococcal rhinitis was present in all cases, although involvement appeared limited to the caudal nasal cavity in most cases. Typical signs of nasal cavity disease, such as sneezing and nasal discharge, were often absent. Treatment of nasopharyngeal cryptococcosis should include physical dislodgement or debulking of lesion(s) to provide immediate alleviation of upper airway obstruction, followed by systemic antifungal therapy to eliminate residual infection from the nasal cavity. Infections caused by Cryptococcus neoformans var gattii accounted for a disproportionately large number of these cases. 相似文献

Metrizamide myelography was used in five dogs and two cats with signs of spinal cord disease. The history, clinical signs, cerebrospinal fluid examination, and myelography supported a presumptive diagnosis of spinal cord neoplasia in all seven animals. Myelography demonstrated a deviation of the subarachnoid space in each of them. Five of the animals had an expansile intramedullary spinal cord lesion causing thinning and peripheral deviation of the subarachnoid space. Two had extramedullary lesions causing a central deviation of the subarachnoid space. Spinal cord tumors in six of the seven animals were confirmed by necropsy or surgical excision and histopathologic examination. In the seventh animal, a spinal cord fungal grapuloma was diagnosed by necropsy. 相似文献

Bilateral exudative chorioretinitis was diagnosed in an 18‐month‐old male neutered ferret (Mustela putorius furo) with a generalized Cryptococcus gattii infection confirmed by PCR. The animal was referred to the Ophthalmology Service of the Autonomous University of Barcelona (VTH‐UAB) for acute onset blindness. Complete ophthalmic examination revealed absent menace response and dazzle reflex in both eyes (OU), as well as subretinal edema located in the tapetal fundus. At that time, the clinical ophthalmologic diagnosis was bilateral exudative chorioretinitis. Treatment with prednisone (0.5 mg/kg PO q24 h) was instituted in addition to the ongoing treatment with fluconazole (10 mg/kg PO q24 h). The following rechecks revealed secondary cataracts with subsequent lens subluxation and panretinal degeneration OU. Despite being blind and the poor prognosis of disseminate cryptococcosis, the patient remained active and in good body condition during 6 months after the initial diagnosis. At that time, the ferret showed ataxia, incontinence, and generalized pain. A magnetic resonance imaging study revealed a mass affecting the spine. The owners declined further investigations and the ferret was humanely euthanized. The postmortem histopathology confirmed the initial diagnosis of cryptococcosis and the presence of intraretinal Cryptococcus spp. To the authors’ knowledge, this is the first report of Cryptococcus spp. induced exudative chorioretinitis in a ferret. 相似文献
