Familinal arteriovenous malformations (AVM) are uncommon findings. In this papaer, we reported a family, father and son presented intracranial hemorrhage due to ruptured AVM. The patient, a 60-year-old man, presented sudden disturbance of consciousness with severe headache. A CT scan demonstrated large intracerebral hematoma in the right temporo-occipital region. An angiogram showed mixed dural and pial AVM, fed by middle meningeal artery, occipital artery and a branch of middle cerebral artery. The 36-year-old son of the first patient also suddenly fell into semicomatose state. A CT scan revealed intraventricular hematoma and an angiogram demonstrated AVM fed by anterior choroidal artery. Only 9 families were reported in English and Japanese literatures. According to the literaturtes, age, sex preponderance, site of lesion were not specific in the familial cases of AVMs comparing with the non-familial ones. Due to the rarity of familial AVMs, it is difficult to clarify that the occurrence is hereditary or coincidental.
