Olfactory neuroblastoma: imaging by magnetic resonance, CT and conventional techniques

Abstract: Twenty-four patients with the histological diagnosis of olfactory neuroblastoma have been treated at the Royal National Throat, Nose and Ear Hospital since 1975. The tumour showed a bimodal age distribution and 30% of the patients were under 30 years of age. The imaging characteristics on plain film, computed tomography and magnetic resonance combined with intravenous gadolinium DTPA are detailed. None of the changes described is wholly specific. However, a tumour in the ethmoids and upper part of the nasal ca… Show more

“…The radiographic appearance presents a broad differential diagnosis which should include carcinomas, sarcomas, melanoma, rhabdomyosarcoma, and malignant lymphoma. Less aggressive entities, which could mimic the appearance of ENBs, include benign cysts and tumors, such as inverting papilloma, hemangioma, and nasal polyps as well as neurogenic tumors, such as neurofibroma, ganglioneuroma, nasal meningocele, and encephalocele [13-14].…”

“…Contrast enhanced CT will demonstrate a homogeneously enhancing mass, while non-enhanced zones may suggest regions of necrosis. The extent and delineation of tumor is best determined by MRI with and without contrast, with T1-weighted images showing marked enhancement after gadolinium injection [4,7].…”
