Case Discussion

A meningoencephalocele is a herniated brain tissue, meninges and CFS through cranial defect. It is a rare find in the adult population, more commonly found in the pediatric age group where there is congenital non-fusion of the cranial floor.

In adult patients, it is typically associated with a traumatic event or manipulation iatrogenic site. This patient did not present the typical symptoms, and was considered an incidental finding in MRI.

This case was kindly provided by Dr Rodrigo Dias Duarte.
