Prior to World War II there was little in the American literature regarding possible neurologic complications accompanying or following infection with the Schistosoma. Recently, several reports have appeared describing the surgical removal of large granulomatous lesions and subsequent treatment with antimony compounds.1The circumstances in these cases have been similar to those described earlier by Greenfield and Pritchard2and Shimidzu.3We recently have had under our care a case of cerebral schistosomiasis with multiple small subcortical and cortical granulomas and generalized cerebritis, with recovery following cortical biopsy, cerebral decompression and treatment with antimony potassium tartrate. The case is of particular interest in that the patient was asymptomatic until ten months after discharge from the army, that his symptoms closely simulated those of neoplasm and that, unlike recently reported cases, no large granulomatous mass was found.
