Mucocele of the sphenoid sinus: a rare entity to keep in mind

Isolated sphenoid sinus mucocele (SSM) is a rare entity that can result in serious sequelae if diagnosis and treatment are inappropriately delayed. Typically, mucoceles are asymptomatic, and they are accidentally identified after computed tomography scan or magnetic resonance imaging of the maxillofacial area performed for other pathological issues. We report a case of isolated SSM that presented only with a headache for over a year, and also review the literature regarding surgical management of such an entity.
