Figure 1
Preoperative CT/MRIs. (A) Axial T1-weighted images showing an anterior clinoidal mucocele (arrow). (B) Axial T2-weighted images showing an anterior clinoidal mucocele (arrow). (C) Coronal T2-weighted image showing that the left optic nerve (arrow head) exists more medially than the mucocele (arrow). (D) Coronal CT suggesting that the mucocele dissolves the anterior clinoidal process and optic strut (arrow). There are onodi cells bilaterally (square).

Operative field view (from the direction of the arrow). (A) After the left pterional craniotomy, the mucocele was exposed (circle) through an extradural approach. (B) The mucous membrane is held with forceps. (C) Operative field after removing the mucous membrane. Dot circle indicates the anterior clinoid process space.
