Sphenoid encephalocoele

Discussion:

Combination of thin CT of the base of skull and MRI with fat saturated T2 sequence are essential in the diagnosis and characterization of suspected dural defects / encephaloceles. 

This patient went on to have surgery (transsphenoidal) with repair of the encephalocoele and resection of the gliotic brain. 

Medial sphenoid encephalocoeles are increasingly recognized in patients with preexisting intracranial hypertension, in many instances undiagnosed until post encephalocoele repair.
