Abstract in Portuguese (Brasil)
A criptococose é uma micose sistêmica de distribuição mundial que afeta humanos e animais. Em caninos, a enfermidade ocorre principalmente no sistema nervoso central e atinge freqüentemente as leptomeninges. O caso aqui relatado demonstrou clinicamente ataxia, quedas, tremores musculares e desequilíbrio. Ao exame macroscópico do encéfalo, havia espessamento das leptomeninges e dilatação dos ventrículos laterais, terceiro e quarto ventrículos. Os achados histológicos incluíram leptomeningite e p ...
A criptococose é uma micose sistêmica de distribuição mundial que afeta humanos e animais. Em caninos, a enfermidade ocorre principalmente no sistema nervoso central e atinge freqüentemente as leptomeninges. O caso aqui relatado demonstrou clinicamente ataxia, quedas, tremores musculares e desequilíbrio. Ao exame macroscópico do encéfalo, havia espessamento das leptomeninges e dilatação dos ventrículos laterais, terceiro e quarto ventrículos. Os achados histológicos incluíram leptomeningite e plexo-coroidite granulomatosa difusa e moderada, com grande quantidade de blastoconídios redondos ou ovais, com cápsula espessa e positivas às colorações de mucicarmina de Mayer, ácido periódico de Schiff (PAS) e prata metanamina de Grocott. Dados relativos à patologia, sinais clínicos e possíveis fontes de infecção são discutidos. ...
Abstract
Cryptococcosis is a systemic mycosis that affects humans and animals worldwidely. In dogs, the disease typically affects the central nervous system with involvement of leptomeninges. In this case, the clinical findings were ataxia, seizures, muscle tremors and loss of equilibrium. Thickening of leptomeninges and dilation of the lateral, third and fourth ventricles were observed in the macroscopic examination of the brain. Histological findings included diffuse moderate granulomatous leptomening ...
Cryptococcosis is a systemic mycosis that affects humans and animals worldwidely. In dogs, the disease typically affects the central nervous system with involvement of leptomeninges. In this case, the clinical findings were ataxia, seizures, muscle tremors and loss of equilibrium. Thickening of leptomeninges and dilation of the lateral, third and fourth ventricles were observed in the macroscopic examination of the brain. Histological findings included diffuse moderate granulomatous leptomeningitis and choroiditis. In association with the inflammatory lesions, there were large numbers of round and oval blastoconidia with thick capsule and stainable with Mayer’s mucicarmine, periodic acid Schiff (PAS) and by Grocott’s methenamine silver. Data related to pathology, clinical signs and possible method of infection are presented and discussed. ...
