F-18 FDG PET/CT staging and posttherapeutic assessment of esthesioneuroblastoma.

Esthesioneuroblastoma is an uncommon head and neck neoplasm with frequently delayed diagnosis resulting from its nonspecific symptomatology. CT and MR are the mainstream cross-sectional imaging modalities for the evaluation of this lesion, which has a propensity to disseminate to cervical lymph nodes at initial presentation. The authors present an additional case of this rare olfactory neuroendocrine tumor with accurate anatomic and functional staging and posttherapeutic surveillance by PET/CT.
