Bilateral superior concha bullosa: a rare case overlooked.

Concha bullosa is generally defined as the pneumatization of the middle turbinate and, rarely, of the superior or the inferior turbinates. A symptomatic pneumatization of the superior turbinate is extremely rare. When symptomatic, concha bullosa may cause various problems. Concha bullosa can be easily recognized in paranasal sinus computed tomography. In this article we present a very rare case with bilateral pneumatization of the superior turbinates in a patient with relevant symptomatology.
