The tumoral form of schistosomiasis: report of a case with cerebellar involvement.
The tumoral form of schistosomiasis mansoni is rare and has not been described in the brain, in which schistosome eggs usually elicit a granulomatous inflammation. A 20-year-old Brazilian man had the tumoral form of schistosomiasis of the cerebellum which was treated surgically. Histological study of the excised cerebellar mass demonstrated a massive granulomatous reaction around Schistosoma mansoni eggs and massive necrotic areas. To our knowledge, this is the first case of schistosomiasis mansoni of the brain presenting as a posterior fossa mass with the characteristic necrotic granulomas.
