Spontaneous Extradural Hematoma Caused by Dural Hemangioma: Case Report

Acute intracranial extradural hematoma in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. We report a case of spontaneous extradural hematoma due to vascular malformation of dura. A 35 year old male patient presented with sudden onset of loss of consciousness. On examination, the patient was comatose with a Glasgow Coma Score of 3. Urgent CT scan revealed a large extradural hematoma, for which he was operated. Intraoperatively he had a torrentally bleeding vascular lesion (hemangioma). We ligated external carotid artery and than only we could remove the tumor. He was gradually weaned off from ventillator and was later on discharged from hospital. He continues to be in vegetative state till last follow up.
