[Spinal infarction in the anterior spinal territory with possible relation with bilharziasis].

We report a case of spinal cord infarction in the anterior spinal artery territory with selective involvement of the anterior horns. A 35-year-old Mauritanian woman was hospitalized because of an acute and severe flaccid paraplegia without any sphincter dysfunction or sensory disturbance. MRI abnormalities (hypersignal on T2-weighted sequences) were restricted to the anterior horns of the lower thoracic spinal cord and conus medullaris. Adamkiewicz's artery appeared abnormally thin at arteriography. The infarction was probably related to vasculitis of schistosomal origin.
