A concha bullosa is a common anatomic variant that represents an aerated turbinate, usually the middle turbinate. It is usually asymptomatic. When extensively pneumatized, a large concha bullosa may cause significant problems, including headache, nasal obstruction, and blockage of sinus drainage. We report a case of a large concha bullosa mucopyocele that manifested as recurring migraine headaches. It was successfully treated with surgical excision. We also review the available literature.
