Bochdalek hernia is a congenital posterior diaphragmatic defect resulting from failure of the retroperitoneal canal membrane to fuse with the dorsal esophageal mesentery and the body wall. A recent computed tomography study indicated that these defects frequently can be identified on routine chest and abdominal images, and classified them as small, medium, and large, the large ones being identifiable on five or more contiguous axial scans consisting of 1-cm-thick sections. Although the overall prevalence of Bochdalek hernias is 6%, and that of bilateral hernias is 0.9%, to date only a few patients with unilateral or bilateral large hernias have been reported. This article describes an adult with asymptomatic, bilateral, large Bochdalek defects containing herniated retroperitoneal fat.
博赫dalek疝是一种先天性后膈缺损，由腹膜后管膜未能与背侧食管系膜和体壁融合所致。最近一项计算机断层扫描研究表明，这些缺损在常规胸部和腹部图像上常常能够被识别，并将其分为小、中、大三类，大的缺损在由1厘米厚层面组成的连续5层或更多层轴向扫描上能够被识别。尽管博赫dalek疝的总体患病率为6%，双侧疝的患病率为0.9%，但迄今为止，仅有少数单侧或双侧大疝患者被报道。本文描述了一名患有无症状双侧大博赫dalek缺损且伴有疝出腹膜后脂肪的成年人。
