RESUMO
Schistosomiasis of the central nervous system is uncommon. Schistosoma mansoni is the most common cause of a spinal cord lesion, although Schistosoma haematobium is sometimes responsible. The conus medullaris is the primary site for spinal lesion. The spinal lesion of schistosomiasis may be in the form of a mass lesion or acute necrotizing myelitis, or it may be silent and symptomless. Diagnosis of spinal cord schistosomiasis is commonly retrospective but may be suggested by laboratory and radiological studies. We were confronted with a case of bilharzial granuloma of the conus in a 7-year-old boy. This patient sought treatment for sphincteric disturbance. Myelography showed an intradural lesion in the area of the conus (opposite L1-L2). The mass proved pathologically to be S. haematobium granuloma. There was no previous history of bilharzial infestation. The neurological deficits improved markedly after surgery and antibilharzial treatment.
