Presentation
Headache and right proptosis. Resected left frontal meningioma a year ago.
Patient Data
The right temporal extra-axial lobulated lesion, which appears hypointense T1W and isointense T2W and FLAIR sequences, shows homogenous enhancement with dural tail, anterior to the temporal lobe and bulged into the orbit as an extra conal mass splaying extra-ocular muscles and optic nerve, causing proptosis
The lesion extends to the right cavernous sinus and encased the cavernous segment of the right internal carotid artery, which is significantly narrowed but demonstrates a preserved flow void
Post-treatment changes as left frontal craniotomy and underlying left frontal cortical and subcortical region malacic change surrounded by gliosis.
Case Discussion
Spheno-orbital meningioma (SOM) is a rare complex tumor that arises from the sphenoid wing, extends into the orbit, and is associated with sphenoid bone remodeling and hyperostosis. This tumor often invades the cavernous sinus and the important neurovascular structures of its.
