Abstract:
A 56-year-old man presented with intermittent epistaxis. Nasopharyngoscope revealed a hemorrhagic mass occupying the left nasal cavity. The patient had a history of renal clear cell carcinoma. F-FDG PET/CT was performed to evaluate the potential lesions systematically. PET/CT images showed low to moderate activity in the region of nasal cavity and paranasal sinuses. No abnormal uptake of F-FDG was observed in the rest of the body. Eventually, the mass was pathologically proved to be metastatic renal clear cell carcinoma.
