Case contributed by Dr Ammar Haouimi

Presentation

Epilepsy

Patient Data

Age: 10 years
Gender: Female
MRI

The MRI sequences demonstrate a large well-defined extra-axial left frontal mass of parasagittal location centered on the olfactory groove/planum sphenoidale with CSF cleft sign. It displays a low signal on T1WI, inhomogeneous high signal on T2WI with central areas of bleeding causing high signal on T1WI, and low signal on T2WI/GE as well as focal cystic changes. The postcontrast sequences show an intense and heterogeneous enhancement with central necrosis. A mass effect is noted on the falx cerebri, and frontal horns.

Case Discussion

MRI features suggestive of a meningioma of the anterior cranial fossa with intra-tumoral bleeding and cystic changes.

Pediatric meningiomas are relatively rare tumors with an incidence ranging from 0.4 to 4.6% before the age of 16 years 1. Usually seen in the setting of a neurofibromatosis type 2 (NF2) 1.
