Diffuse pseudotumoral cerebral Schistosomiasis mansoni: a new form of presentation / Forma pseudotumoral difusa da esquistossomose cerebral: uma nova forma de apresentação

ABSTRACT

We describe two cases of cerebral schistosomiasis mansoni with multiple pseudotumoral lesions diagnosed by stereotactic brain biopsy. Both patients presented with seizures and one with left visual impairment. Imaging techniques revealed multiple brain lesions involving cerebral parenchyma, pons, cerebellum and thalamus. Brain histopathologic specimens of the patients showed multiple schistosomal granulomas in distinct evolutive phases. All patients presented good clinical response to treatment and reversion of the brain lesions. This new form of neuroschistosomiasis must be considered by those who work in the endemic area for Schistosoma mansoni.
