摘要
目的探讨异位支气管囊肿的CT及MRI表现。资料与方法回顾性分析19例经手术及病理证实的异位支气管囊肿患者资料,讨论并复习其CT及MRI表现。结果椎管内8例,颈部3例,颅内3例,皮下组织2例,左侧肾上腺区、腹膜后及蝶窦内各1例。病变多为类圆形及椭圆形,偶有分叶,边界清楚,在CT像上呈较高密度影或囊性密度影,在MRI上呈长T1、长T2信号或双高信号,均无强化。异位支气管囊肿可继发感染并伴有先天畸形或肿瘤。结论异位支气管囊肿发病部位及临床表现缺乏特异性,CT及MRI有助于病变定位,明确病变性质,但要发现其支气管来源需依靠病理。
Objective To investigate the ectopic bronchogenic cyst on CT and MRI.Materials and Methods 19 cases of ectopic bronchogenic cyst confirmed by surgery and pathology were Collected.Their CT and MRI imaging findings were retrospectively analyzed.Results Of 19 cases,cervical spinal canal 8 cases,neck 3 cases,intracranial 3 cases,subcutaneous tissue 2 cases,the left adrenal gland 1 case,retroperitoneal 1case,and sphenoid sinus 1 case.Lesions were mostly oval and oval-shaped,sometimes leaf,clear boundary,in high density on CT showed a cystic-density film and video,on MRI showed long T1 and long T2 signal or dual high signal.No enhancement.It might be secondary to infection,associated with congenital malformations or tumors.Conclusion The anatomical site and clinical manifestations of ectopic bronchogenic cyst has no specificity.CT and MRI are conducive to judge the location and characteristics of the lesions.But it is diagnosed with bronchial cyst by pathology only.
