Presentation
Right vision loss
Patient Data
A right sided expansile bone lesion at the anatomical location of 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. There was no direct connection between any paranasal sinus and the mass cavity. Features are suggestive of mucocele of the right anterior clinoid process
MRI showed a right-sided small oval shape mass, compressing the optic nerve, in the medial portion of the right anterior clinoid process. There was no direct connection between any paranasal sinus and the mass cavity.
Case Discussion
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.
