A case of spontaneous intracranial extradural hematoma is presented. A 11-year-old girl was admitted to a local hospital, because of fever, headache, and vomiting. At that time the patient was drowsy and incontinent of urine. Computerized tomography showed a large left frontal hematoma and she was transferred. Admission examination revealed a somnolent but well oriented girl with a temperature of 37.4℃. There was bilateral papilledema with retinal bleeding. Routine laboratory studies revealed moderate leucocytosis and an increased erythrocyte sedimentation rate. Angiography revealed a left frontal, large hypovascular mass with a pseudoaneurysm of the middle meningeal artery. Craniotomy disclosed an extradural fresh clot and arterial bleeding from the middle meningeal artery in the well-developed granulation tissue. Histologically, this granulation tissue contained numerous dilated vessels and focal hemorrhages.
