Cervical intramedullar schistosomiasis as a rare cause of acute tetraparesis.
BACKGROUND
The trematode infection schistosomiasis affects at least 200 million people in endemic areas. Granulomas cause the typical manifestations of urogenital, intestinal and hepatolienal schistosomiasis. Involvement of other organs especially the central nervous system (CNS) is uncommon.


METHODS
We describe a 40-year old male with a history of repeated contact with schistosome contaminated water. After having suffered from flu-like symptoms with fever and arthralgias, he first presented with a polyradiculopathy of unknown origin. Then 4 weeks later an acute tetraparesis occurred. Spinal magnetic resonance imaging (MRI) revealed a spinal stenosis and query medullary hyperintensities at C6-C8 without contrast-enhancement. Serologic testing was positive for schistosomiasis. The intraoperative appearance at decompressive laminectomy revealed a myelitic form of schistosomiasis. Under therapy with praziquantel, initially high dose cortisone and intensive physiotherapy, symptoms slowly improved over months. On follow-up 1 year later, the patient presented with a spastic distally marked tetraparesis and sensory impairment from C6 downwards.


CONCLUSIONS
Cervical intramedullar schistosomiasis is a rare cause of acute tetra- or para-paresis in patients, who have had contact with schistosomes. Early diagnosis is essential because of the excellent prognosis with specific therapy.
