Approximately 3 x 2 x 3 cm extra-axial left sided pericavernous mass along the medial surface of the left temporal lobe causing marked compression of the left optic nerve within the orbital apex and along its anterior intracranial portion. It abuts the left internal carotid artery without encasement or narrowing. It deviates the artery posteriorly and medially. Superiorly the mass is in direct course of the left oculomotor nerve. There is elevation of the left lateral aspect of the pituitary gland.
The mass is circumscribed and has a well-defined thin T2 dark rim along its posterior lateral aspects. It is moderately T2 bright. On post gadolinium injection the mass demonstrates progressive enhancement which begins centrally and proceeds craniocaudally.
No edema or invasive features. Normal fat preservation in the left pterygopalatine fossa.
Absent left ocular lens.
