Case Discussion

MRI showed a small oval shape mass, compressing the optic nerve, in the medial portion of the right anterior clinoid process. The medial portion of the anterior clinoid process surrounding the mass was eroded and the bony margins of the mass were well corticated in computed tomographic scans. There was no direct connection between any paranasal sinus and the mass cavity. The pathological diagnosis after the operation indicated a mucocele.

Pathology:

Benign fibrous cyst wall focally lined by pseudostratified (respirtaory type) epithelium. Histomorphology is compatible with mucocele.
