Abstract
|
|
|
|
A 54-year-old man presented with an incidentally identified intensely hypermetabolic lesion (SUVmax: 22.2 g/mL) in the left maxillary sinus on 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) performed for cancer screening. The mass was well circumscribed and showed solid enhancement on contrast-enhanced CT. Histological examination of the mass was consistent with oncocytic schneiderian papilloma. It is of prime importance to recognize that a sinonasal lesion with intense hypermetabolism on 18F-FDG PET/CT does not necessarily signify malignancy. Oncocytic schneiderian papilloma should be included in the differential diagnosis of an intensely hypermetabolic and solidly enhancing mass of the nasal cavities or paranasal sinuses.
