Infected Concha Bullosa Mucocele: A Case Report

Concha bullosa (CB) is a common sinonasal anatomic variant. The obstruction of a CB, though rare, might result in mucocele that may be misdiagnosed. In this report, we present a case of a 32-year-old female with a one-year history of unilateral nasal obstruction, headache, facial pain, foul nasal discharge, and hyposmia, initially misdiagnosed as a neoplasm. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a right middle CB infection with a mucocele. Laboratory cultures yielded . Endoscopic sinus surgical mass excision was performed, and treatment with oral cefuroxime was administered. The patient recovered fully. A CB mucocele, though rare, should be considered in the differential diagnosis of an intranasal mass.
