摘　　要：目的探讨CT和MRI诊断鼻咽纤维血管瘤(JNA)术后复发的应用价值。方法回顾性分析20例JNA术后复发患者的临床资料、CT及MRI表现。结果患者术后均未进行规范性随访,平均于2.4年后症状再次出现时诊为肿瘤复发。CT显示复发肿瘤多以蝶腭孔为中心,广泛累及周围结构,包括颅底及颅内结构。MRI能更准确地显示肿瘤范围。结论采用CT和MRI对JNA术后患者行规范性随访检查对早期发现肿瘤复发极为重要。Objective To investigate the diagnostic value of CT and MRI in postoperative recurrence of juvenile nasopharyngeal angiofibroma （JNA）. Methods Clinical data, CT and MRI characteristics of 20 patients with recurrent JNA were analyzed retrospectively. Results Standard postoperative follow-up was not performed, and tumor relapse were diagnosed about 2.4 years later on average for the recurrence of symptoms. Most recurrent tumors located in sphenopalatine foramen with severe adjacent infiltration including basilar and intracranial structures in CT. MRI was better in demonstration of tumor extent than CT. Conclusion It is essential for patients in postoperative of JNA to examine early tumor recurrence with CT and MRI.
