Abstract
Anterior clinoid process (ACP) mucoceles are an uncommon entity and an even rarer cause of visual impairment. We review the case of a 62-year-old female with a 2-year history of progressive right-sided monocular vision loss. Paranasal sinus computed tomography (CT) scan showed bilateral ACP pneumatization. A soft tissue density mass occupied the right ACP with bone expansion and compression of the right orbital canal. An endonasal approach was performed with total vision recovery. Dedicated images are necessary to diagnose ACP. On CT, the affected sinus will have bone erosions. On magnetic resonance imaging, the signal intensity is determined by its protein concentration and mobile water protons. ACP mucoceles’ accurate diagnosis determinates the treatment and surgical approach. Finally, the correct management selection will determine the retrieval of the visual ability.
