Management of FDG avid Benign Sinonasal Schneiderian Papilloma: A Case Report and Review of the Literature

Aberrant Hypermetabolism of Nasal Leiomyoma Mimicking Malignancy on 18 F-FDG PET/CT

ABSTRACT

Leiomyomas are benign tumors that commonly arise from the uterus. They rarely occur in the nasal cavity. Leiomyomas and leiomyosarcomas are clinically similar and may be difficult to distinguish preoperatively. Although PET has been reported to be useful for evaluating uterine smooth muscle tumors, the use of PET for evaluating sinonasal leiomyoma has not yet been reported. Here, we describe the images of a patient with leiomyoma of the nasal septum in whom intense FDG uptake was noted on PET/CT.
