Esthesioneuroblastoma: An Unusual Presentation with Intractable Headache.

Esthesioneuroblastoma, also known as olfactory neuroblastoma, is a malignant tumor of the upper nasal cavity. This report illustrates the case of a 63-year-old woman who presented with intractable headaches. Subsequent radiologic evaluation and correlation with histopathologic analysis confirmed esthesioneuroblastoma. We review herein the typical computed tomographic (CT) and magnetic resonance (MR) imaging findings related to this locally destructive tumor, the prompt diagnosis of which may help prevent long-term morbidity and potentially, mortality. Up-to-date diagnostic criteria, staging, and management considerations are also outlined.
