Summary: We studied a case of olfactory neuroblastoma by noting ¹²³I-metaiodobenzylguanidine (MIBG) uptake revealed by single-photon emission CT (SPECT). MR imaging revealed an enhancing tumor extending from the left nasal cavity to the bilateral anterior frontal cranial fossae. SPECT revealed high ¹²³I-MIBG uptake in the enhancing tumor. SPECT-revealed ¹²³I-MIBG uptake appears to be clinically useful for distinguishing olfactory neuroblastomas from other tumors, especially suprasellar meningiomas.
