Dural Cavernous Angioma Mimicking a Meningioma and Causing Facial Pain

Abstract

An 18-year-old girl who had severe headaches in the left temporal and facial regions was found to have a small enhanced dural-based parietal convexity mass. On magnetic resonance imaging (MRI), this mass was homogeneously enhanced with "dural tail sign," and was similar to a meningioma. This mass was completely removed surgically, and pathology proved it to be a cavernous angioma without previous hemorrhages. The patient's facial pain was dramatically relieved after surgery. A small dural mass causing severe facial pain is an unusual situation. The lack of hemosiderin in the extra-axial cavernous angioma often leads to the preoperative diagnosis of meningioma.
