Cerebral Schistosomiasis: case report and review of literature

ABSTRACT

Schistosomiasis is an infection caused by trematodes (flatworms from the phylum Platyhelminthes), which are acquired transcutaneously by swimming in contaminated waters. The central nervous system (CNS) schistosomiasis is a rare presentation of the disease. Brain infection to S. Mansoni has been rarely reported, in anedoctal fashion. It should be recognized early, since it disposes a specific treatment, and this treatment may prevent neurological deterioration. A high index of suspicion is necessary, mainly in patients coming from endemic areas, with brain or spinal cord lesions associated with eosinophilia and inflammatory CSF. Finding eggs from schistosoma into excrements or CNS biopsy confirms the diagnosis. We describe a 35-year old Brazilian man, harboring an isolated brain infection to S. mansoni.
