Many common anatomic variations in the nasal cavity have been observed, including paradoxical turbinates and pneumatization of the inferior, middle, and superior turbinates. We describe a case of a rare anomaly—unilateral inferior turbinate agenesis—in a 65-year-old man who had presented with epistaxis. During evaluation, anterior rhinoscopic examination revealed the absence of the right inferior turbinate; this finding was confirmed on computed tomography. The patient had never undergone nasal or sinus surgery, and he denied ever having expelled anything of significance from his nasal cavity. This case merits attention because of the rarity of reports on turbinate agenesis.
