摘　　要：目的探讨椎管内支气管源性囊肿的磁共振表现特点。方法回顾分析国内文献报道的33例有关椎管内支气管源性囊肿的MR表现，结合本院经病理证实的5例，总结椎管内支气管源性囊肿的MR表现特点。结果文献报道发生于椎管内的支气管源性囊肿共33例，其中男23例，女lO例，平均年龄24．1岁。发生于颈段、胸段及腰段的分别为13、10、7例，枕骨大孔处3例。本院5例中男4例，女l例，1例发生于枕骨大孔处，余4例发生于颈段脊髓，MRI表现为囊性占位，囊壁轻度强化或不强化。结论椎管内支气管源性囊肿的MR表现有一定的特征，MRI可显示囊肿的性质、部位及范围，有助于术前诊断。Objective To investigate the MRI findings of spinal bronchogenic cyst （SBC）. Methods The MR imaging data of 5 cases with pathologically proved SBC were analyzed retrospectively, and the literature of SBC were reviewed. Results 33 cases were reported in the literature. Among them, 23 cases were male and 10 cases were female, mean age was 24.1 years. Cervical segments in 13 cases, thoracic segments in 10 cases, lumbar segments in 7 cases, and the vicinity of the foramen magnum in 3 cases. Among the 5 cases in our hospital, 4 cases were male and 1 case was female, 1 case was located in the vicinity of the foramen magnum, the others were located in cervical segments. On MRI, the SBCs were showed cystic lesions, low signal intensity on T~ WI and high sig- nal intensity on T2 WI. The capsule wall showed slight enhancement or no enhancement. Conclusion There are some characteristic MRI findings of SBC. MRI can demonstrate the location, size and characteristics of SBC, which may be helpful in the preoperative diagnosis.
