—Case Report—

抄録

A rare case of true aneurysms of the middle meningeal artery (MMA) associated with cavernous hemangioma in a 47-year-old male is presented. Angiography showed aneurysmal dilatation of the MMA, which was a tumor feeder. Histological examination confirmed the true aneurysmal character of the dilatation. The aneurysms were considered to result from increased hemodynamic stress and medial defects in the MMA.
