In the parasellar region, Anterior Clinoid Process (ACP) with its supporting structures like Optic Strut (OS), medial part of lesser wing of the sphenoid and roof of the optic canal are certain bony landmarks related to important elements like the cavernous sinus, Internal Carotid Artery (ICA), Optic Nerve (ON) and the pituitary gland.

The lesion was causing thinning and pressure erosion of the posterior wall of maxillary sinus, pterygoid plate, posterior wall of orbit, medial wall of sphenoid on the left side, left lesser wing of sphenoid, and was causing thinning of left anterior clinoid process.
