title: Incidental Detection of Ossifying Fibroma of the Frontal Sinus on 99mTc-MDP Bone Scan.
abstract: Sinonasal ossifying fibroma is rare and frequently occurs in young adulthood with a female predominance. We present a case of a 48-year-old man with a history of newly diagnosed lung cancer, referred for whole-body bone scan for evaluation of metastatic disease, which showed 2 focal intense areas of tracer uptake in the frontal sinus region without other abnormalities. SPECT/CT revealed the activities were located in the frontal sinus, associated with scattered calcifications and well-defined margins. The postoperative pathological diagnosis was ossifying fibroma.
