Schistosomiasis of the spinal cord.

Schistosomiasis of the spinal cord is a rare presentation of a disease involving over 200 million people. A patient from an endemic area presenting as a transverse myelitis or a spinal cord tumor, and with eosinophilia, should alert the physician to the possibility of schistosomiasis of the spinal cord. Diagnosis is based on finding the characteristic eggs in the stool or urine, or if necessary, by rectal, bladder or liver biopsies. Myelography is performed to determine if decompressive laminectomy is necessary.
