摘　　要：目的探讨腹腔异位支气管囊肿(BC)的影像特征,以提高对本病的认识。方法回顾性分析经手术和病理证实的9例BC患者的CT和临床资料,7例行CT增强扫描(2例平扫加增强,5例直接增强),2例仅行CT平扫,其中2例加行MRI平扫。结果贲门及胃底5例,左侧肾上腺区3例,骶尾部1例;病灶表现为类圆形或椭圆形、不规则软组织或液性密度肿块影,病灶最大径为2.0~10.7cm,平均4.9cm。囊肿内部CT值小于20HU1例,CT值20~60HU8例。5例可见边缘钙化;增强扫描仅1例囊壁明显强化,囊内容物未见强化。病变T1WI呈低或高信号,T2WI呈显著高信号。结论BC在CT及MR表现上有一定特征性。Objective To determine the image characteristics of abdominal bronchogenic cyst. Methods The clinical findings and CT/MRI manifestations of 9 patients with pathologically confirmed extrapulmonary bronchogenic cysts were retrospectively analyzed. The patients underwent CT without (2) or with (7) contrast enhancement as well as MRI (2). Results Lesions were located in the abdomen and pelvis including gastric cardia and fundus (5),left adrenal gland (3),sacrum and coccyx (1). The lesions were round,elliptical or irregular cystic masses measuring 2.0-10.7 cm in diameter (average: 4.9 cm) with CT densities of 20-60 HU (8) or less than 20 HU (1),marginal calcification (5),no (8) or mural (1) contrast enhancement. On MRI,the cysts were T1 iso- or hypo-intense and T2 hyperintense. Conclusion CT/MRI characteristics combined with comprehensive clinical analysis can aid the diagnosis of extrapulmonary bronchogenic cysts.
