A 75-year-old woman was admitted to our hospital because of sudden onset of paresis in her left arm and face. She had untreated hypertension and hyperlipidemia. When she came back home after playing with children in the park, she felt weakness in her left hand. On admission, physical examination revealed that her blood pressure was very high (200/102mmHg). Only slight weakness in her left arm and left facial palsy were recognized neurologically. An electroencephalogram showed normal findings. Brain CT and MRI revealed a venous angioma near the right central sulcus. Gadolinium-DTPA enhanced MRI showed a group of small radiating veins(so called "the caput medusae sign") connected to the venous angioma. The remaining symptoms decreased with the normalization of blood pressure. It is suggested the intracranial motor tracts of the face and arm in the precentral gyrus are adjacent to the location of this venous angioma. The dilation of venous angioma due to high blood pressure was thought to cause the paresis of face and arm in this patient.
