Abstract
We present a 48-year-old woman with an olfactory neuroblastoma who was referred for accurate staging using PET/CT. The Ga-DOTATATE PET/CT showed a 51 × 32-mm mass with an SUVmax of 7.59 in the sphenoidal sinuses, whereas radiotracer uptake on F-FDG PET/CT was similar to that of brain tissue. Ga-DOTATATE PET/CT might be especially useful in regions with difficult tumor visualization resulting from high background, such as brain tissue. The results of this case may suggest that somatostatin receptor imaging in patients with esthesioneuroblastoma may facilitate the potential application of radiotheranostic agents for the treatment of this aggressive subtype of tumors.
