Esthesioneuroblastoma is an uncommon neoplasm arising from the olfactory epithelium and characterized by frequent local recurrences. The purpose of this study was to determine the role of CT and MRI in the diagnosis of recurrent esthesioneuroblastoma. A total of 14 histologically confirmed recurrent esthesioneuroblastomas referred to our institution between 1986 and 1998 was retrospectively reviewed. All patients underwent both CT and MRI. The tumour recurrences displayed a variety of imaging characteristics and aggressiveness. They were typically expansile and destructive in their growth patterns. Erosion of the cribriform plate and involvement of the anterior cranial fossa were common findings. The CT and MRI appearances of recurrent esthesioneuroblastoma do not differ significantly from tumours imaged at initial presentation. Patients should receive close follow-ups and CT/MRI examinations for several years beyond diagnosis, as early diagnosis of recurrent disease predicts survival.
