We describe four cases of the tumoral form of cerebral schistosomiasis mansoni. The patients had symptoms of increased intracranial pressure and focal neurological signs that varied according to the site of the lesion. Computerized tomography showed a hyperdense, enhancing lesion located in the cerebellum (2 patients), frontal lobe and thalamus (1 patient), and temporal subdural region (1 patient), with associated mass effects. The lesion was resected in three patients and a stereotactic biopsy was performed in one. Histopathologic specimens of all four patients revealed multiple schistosomal granulomas in various evolutive phases. Two of these patients differ from previously described cases; one because of the subdural location of the lesion, mimicking a meningioma, and the other one because two lesions were present.
