title: [Accidental discovery of 18F-fluorodeoxyglucose PET/CT-positive papilloma in sinus sphenoidalis in a patient with recurrence of breast cancer].
abstract: A patient suspected for metastatic breast cancer went through an 18F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT). Along with metastatic lymph nodes in the neck it showed high 18F-FDG uptake in a polypoidal structure in the sinus sphenoidalis. When asked she had no related symptoms due to the sphenoid polyp and the CT-scan showed no bone destruction. To rule out malignancy a biopsy was made showing benign sinonasal papilloma of oncocytic origin. High 18F-FDG PET uptake can be seen in benign structures and should therefore not be the only predictor for malignancy.
