Computed Tomography and Magnetic Resonance Imaging of Preoperative Cases of Esthesioneuroblastoma (Olfactory Neuroblastoma): A Case Series

Abstract

Esthesioneuroblastoma is an uncommon aggressive tumour arising from the olfactory epithelium of superior nasal cavity, frequently invading the base of cranium, cranial vault and orbit. Contrast enhanced Computed Tomography (CT) and contrast enhanced Magnetic Resonance Imaging (MRI) were done for three patients which showed modified Kadish stage C tumour. Biopsy was done to confirm the diagnosis and patients were subjected to surgery and radiotherapy. The purpose of this case series was to report the radiological features of esthesioneuroblastoma. This is a report on three cases of different age groups who presented tumour with intracranial extension which were histopathologically proven as esthesioneuroblastoma.
