title: A case of olfactory neuroblastoma detected by (18)F-FDG PET/CT.
abstract: Olfactory neuroblastoma is an uncommon malignant neoplasm of the superior nasal cavity. We report a case of a 78-year-old woman who presented with frontal headache and proptosis of the right eye. CT revealed a nasoethmoid mass with diffuse calcifications. FDG PET/CT demonstrated intense FDG uptake by a main nasoethmoid tumor and metastatic lesions in the cervical lymph nodes. Histologic examination confirmed olfactory neuroblastoma.
