Abstract

The false-positive FDG uptakes on head and neck areas are common due to benign lesion, iatrogenic and physiologic changes. The Schneiderian papilloma is uncommon benign tumor arising from the mucosa of the paranasal sinuses and nasal cavity. The findings of paranasal papilloma on conventional modality such as CT and MRI are non-specific and they could be confused with inflammatory polyp or retention cyst. Despite of benign tumor, the papilloma usually shows locally aggressive growth with malignant potential, therefore the FDG can be actively accumulated in this lesion. We describe the case of 18F-FDG PET/CT finding in a 77-year-old woman who demonstrates oncocytic papilloma in maxillary sinus.
