[Cerebral bilharziasis caused by Schistosoma mansoni].

A 21-year-old French serviceman who had been posted to black Africa on several occasions between 1978 and 1981 was hospitalized in August 1981 with generalized convulsive seizures. The only abnormal finding on clinical, paraclinical and biological investigation was blood hypereosinophilia. A further generalized convulsive fit occurred in August 1982. A CT scan then showed a poorly defined hyperdense occipital area. Pathological examination of the operative specimen confirmed that the lesion was due to schistosoma mansoni. Investigation failed to detect clinical or biological evidence of other parasitic lesions. Specific serology was negative.
