Patient 2. (A) Eight years after surgery, coronal flair MR showing direct contact between the right superior rectus/levator palpebrae superioris and the basal meninges of the frontal lobe, with peaking of the muscle complex (white arrow). Note abnormal bright signal in frontal white matter from brain retraction during pterional craniotomy. (B) Post-gadolinium image showing abnormal enhancement of the basal meninges (black arrowheads), which is contiguous with the superior rectus/levator complex. On the normal side the dark contour representing orbital roof is intact (white arrowheads), along with the fat cushion between the orbital roof and muscle complex.
