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.
嗅神经母细胞瘤是一种起源于嗅上皮的罕见肿瘤，其特征是频繁局部复发。本研究的目的是确定CT和MRI在复发性嗅神经母细胞瘤诊断中的作用。回顾性分析了1986年至1998年间转诊至我院的14例经组织学证实的复发性嗅神经母细胞瘤。所有患者均接受了CT和MRI检查。肿瘤复发表现出多种影像学特征和侵袭性。它们的生长方式通常为膨胀性和破坏性。筛板侵蚀和前颅窝受累是常见表现。复发性嗅神经母细胞瘤的CT和MRI表现与初次就诊时成像的肿瘤无明显差异。患者在诊断后应接受数年的密切随访和CT/MRI检查，因为复发性疾病的早期诊断可预测生存率。
