A case of epilepsia partialis continua was caused by a subdural hematoma. Muscular contractions occurred primarily in the abdominal region. In this instance, the etiology of the syndrome is unique, and the primary involvement of the abdominal musculature is remarkable. Recent neurophysiological studies have shown the abdominal muscles to be separately represented in the cerebral cortex and to have a specific descending pathway in the spinal cord. The case reported here may be the clinical expression of activity in such a neural pathway.
