Periorbital Pain Induced by the Concha Bullosa Fungus Ball: A Case Report

Concha bullosa is characterized by pneumatization of the middle turbinate and is one of the most common variations of the sinonasal anatomy. It is most often asymptomatic. A fungus ball in the concha bullosa is extremely rare, with only two reported cases in the English literature. This article describes a patient with such a fungus ball in the concha bullosa that caused right periorbital pain, specifically in the right medial canthal area, similar to mucosal contact point headache.
