Metástases císticas cerebrais simulando neurocisticercose radiologicamente
Palavras-chave:
Metástase neoplásica, Neurocisticercose, Cisticerco, Doenças cerebrais, Imagem por ressonância magnéticaResumo
CONTEXTO: Metástases cerebrais são complicações comuns do câncer. A ressonância nuclear magnética (RNM), principal método de diagnóstico por imagem nesses casos, mostra raramente imagens císticas. RELATO DO CASO: A paciente era uma mulher de 45 anos de idade, com cefaleia intensa há um mês, refratária à medicação, e câncer de mama tratado previamente. A RNM apresentava critérios diagnósticos para neurocisticercose. Como não apresentou melhora com tratamento clínico, optou-se pela exérese das lesões. O histopatológico mostrou neoplasia maligna epitelioide. CONCLUSÃO: A imunoistoquímica revelou metástase de carcinoma da mama. Mesmo quando a RNM não é característica de metástase cerebral, esta hipótese precisa ser afastada em pacientes com história prévia de câncer.
