Occult spontaneous lateral temporal meningoencephalocele: MR findings of a rare developmental anomaly.

Abstract

We describe a case of an occult lateral temporal meningoencephalocele discovered in a 14-year-old boy during a work-up for minor head trauma. This spontaneous encephalocele resulted from a closure defect at the former sphenoidal fontanelle. Preoperative MR images are presented.
