Overview
Other imaging studies for esthesioneuroblastoma include angiography/digital subtraction angiography, nuclear medicine, nasal endoscopy, and scintigraphy.[1]
Other Imaging Findings
Other imaging studies for esthesioneuroblastoma include angiography/digital subtraction angiography and nuclear medicine.[1]
Angiography/Digital subtraction angiography (DSA)
Angiography demonstrates a prominent tumor blush with arteriovenous shunting, and persistent opacification.
Nuclear Medicine
As with other neuroblastomas, olfactory neuroblastomas are -meta-iodobenzylguanidine, MIBG avid. This potentially helps to differentiate them from other tumors that arise in the region.
Nasal Endoscopy
Nasal endoscopy is helpful for evaluating tumor location, extent and characteristics, as well as for obtaining a biopsy.
Scintigraphy
Since the majority of esthesioneuroblastomas express somatostatin receptors, the use of scintigraphy with a radiolabeled somatostatin analog (111 In-pentoctreotide [111 In-DTPA-D-pheoctreotide]; Octreoscan) has been postulated. This technique has been found to be clinically useful, especially for discriminating between postoperative changes and recurrent or residual tumor after extensive skull base surgery.[2]
