Abstract
|
|
|
Sinus mucocele is epithelial lined benign cystic lesion usually due to obstruction of the sinus ostia. It is commonly seen in frontal and ethmoidal sinus, although rarely, in sphenoid sinus. Anterior clinoid process is bony process on the superolateral aspect of the sphenoid sinus and its pneumatization is observed approximately 9.5% in sphenoid sinus. An anterior clinoid process mucoceles account for merely 1% of paranasal sinus mucoceles and can lead to optic neuropathy, or even dysfunction of third, fourth, sixth cranial nerves due to its proximity to optic canal. There have only been 19 cases of anterior clinoid mucocele causing visual disturbance.
We report a case of mucocele in anterior clinoid process in a 53-year-old man who presented with visual disturbance and ocular pain 1week ago.
