Abstract

A mucocele is a cystic and expansive lesion of the sinus cavities. It is uncommon in the sphenoid sinus and its management is quite challenging especially in low to middle income countries like Cameroon. A 43-years-old female was referred to us by a neurologist for chronic headache and visual disturbances. The pain was unresponsive to analgesics. Physical examination was non-remarkable and a head CT scan realized showed a cyst-like lesion in the sphenoid sinus cavity. Surgical endoscopic treatment was proposed and realized with basic endoscopic instruments, consisting of opening the cavity with drainage of the mucocele. A large opening was made on the anterior wall of the sphenoid sinus, in order to ensure continuous drainage and prevent a recurrence. Sphenoid sinus mucocele is a rare condition, and its diagnosis can be difficult. Confirmation requires specific imaging and treatment is presently well established, but it can be managed with basic tools.

Highlights

A mucocele is defined as a benign expansive pseudo-cyst of the sinus cavities. It is a rare condition made up of a wall consisting of a modified mucosal lining and a viscous liquid content that is generally aseptic [1]
The first reported case of sphenoid mucocele was described by Berg in 1889 [2]
We report a case of bilateral sphenoid mucocele observed at the Yaoundé University Teaching Hospital, Cameroon

Summary

Introduction

A mucocele is defined as a benign expansive pseudo-cyst of the sinus cavities It is a rare condition made up of a wall consisting of a modified mucosal lining and a viscous liquid content that is generally aseptic [1]. We describe the diagnostic methods used and management approach in our setting This is the first case of sphenoid sinus mucocele reported in Cameroon, to the best of our knowledge. A wide opening of the anterior sinus wall permitted drainage of a viscous, yellowish liquid, suggestive of superinfection, with disappearance of the intersinusal septum and fusion of both cavities confirming the diagnosis of sphenoid mucocele. Patients perspective and informed consent: the patient felt completely relieved one month after the surgery and was very happy to return to her daily activities She gave her full written informed consent for the publication of this case report
