[Neurologic manifestations of an easy to treat illness].

A 34 year-old man from Eritrea presented with gradual onset bilateral loin and leg pain. Clinical examination revealed lower abdominal tenderness, ataxia and a tendency to fall backwards. The imaging and lumbar puncture provided new information. Our differential diagnosis included tuberculosis, lymphoma or other granulomatous illness. He was admitted and started on IV methylprednisolone with subsequent resolution of symptoms. Serum ELISA yielded a diagnosis of Schistosomiasis. Consequently treatment with Praziquantel was initiated and steroid therapy continued.
