[A case of sparganosis mansoni cerebri as an epileptogenic lesion]

The authors report a case of sparganosis mansoni cerebri. This 33-year-old man had experienced adversive seizures. Plain CT demonstrated a high density area with surrounding low density area, and homogeneously enhanced with contrast medium in the frontoparietal region. 99TcO4 brain scintigram showed an abnormal hot area. On operating as a cerebral tumor, we had removed a living Sparganum mansoni from the cerebral granuloma. This is the third report in the world to our knowledge of literature, in which alive intracranial Sparaganum mansoni was removed. Sparganosis mansoni cerebri is very rare, and therefore it is very difficult to diagnose exactly before operation. However we should remember this disease considering the life history of the patient with convulsion.
