Abstract

|
|
Schwannoma is a benign tumor arising from the sheath of myelinated nerve fibers and may occur in any part of the body. However, a vidian nerve schwannoma is extremely rare. A 41 year-old man has experienced an occipital area headache and posterior neck stiffness for 2 weeks. Brain computed tomography (CT) angiography, magnetic resonance image revealed lobulated soft tissue density mass in left sphenoid sinus with upward displacement of sphenoid sinus floor and pressure erosion of sphenoid sinus and petrous apex. Ostiomeatal unit CT scan showed a 28×16 mm sized mass filling the left pterygoid canal. The mass was resected using endoscopic sinus surgery. The mass was confirmed as schwannoma. We report a case of vidian nerve schwannoma that was treated by endoscopic sinus surgery.
