Abstract
We describe a case of olfactory neuroblastoma diagnosed by 99mTc-ECD SPECT. Although MRI and CT are very important for delineating these tumors, they are, by no means, specific for neuroblastomas. 131I-MIBG scintigraphy, the standard method for imaging tumors of neural crest origin, also failed to detect a histologically proven esthesioneuroblastoma.
