Resumo
Background: Cryptococcosis is a serious fungal infection contracted by humans and animals, and the most common systemic mycosis found in cats. This disease is often contracted through inhalation of fungal propagules. The Central Nervous System (CNS) may be infected through local extension (nasal and frontal sinuses) or via hematogenous route. Similarly to CNS bacterial infection, the clinical signs of neurological dysfunction may be attributed to mass effect (gelatinous mass of fungal microorganisms and fungal granuloma formation) or to a more disseminated inflammatory response to invading microorganisms. The objective of this study is to report one case of a patient with cryptococcal granulomas in the central nervous system and one case of a patient with neurological signs associated to a cryptococcosis. Cases: Case 1. A 3-year-old male mixed breed feline was admitted to a veterinary clinic, located in Porto Alegre, RS, Southern Brazil. The patient presented unsourced behavioral changes, vestibular ataxia and dysphagia caused by inability of coordination. The following tests were performed: complete blood count test, biochemical analysis, computed tomography scan (CT scan), fluid analysis, radiography and toxoplasmosis test. The following medicine were administrated for treatment: fluconazole, dexamethasone, mannitol, phenobarbital and levetiracetam. Fluid therapy was also part of the treatment. Immediately after death, the cat was submitted for necropsy, and a fungal granulomatous meningoencephalomyelitis was diagnosed. Cryptococcus sp. was identified as the causal agent through pathological findings, fungal culture and PCR analysis. Case 2. One year later, another feline was admitted to the same clinic (a 2-year-old female mixed breed) presenting hypersalivation, tremors and excessive vocalization. The patient had contact with the deceased feline. The following tests were performed: complete blood count...
