True aneurysm of the middle meningeal artery. Case report.

We report the case of a true aneurysm of the middle meningeal artery (MMA) associated with no other pathological findings. After a review of the literature, we emphasize that this case is not associated either with skull traumas, with vascular hypertension or with Paget's disease of the skull. Histological examination and neuroradiological findings confirm the suspicion that this is a case of true aneurysm of the middle meningeal artery.
