The chest and abdominal computed tomography (CT) scans of 940 patients were reviewed to determine the prevalence of Bochdalek hernias and to evaluate the widely held concept that left-sided hernias occur more than nine times as often as right-sided hernias. Sixty Bochdalek hernias were identified in 52 patients, a prevalence of 6%, which is more than 100 times more frequent than previously reported. Left-sided hernias were found approximately twice as often as right-sided hernias. The Bochdalek hernia is a much more common congenital anomaly in the asymptomatic adult than previously thought and frequently can be identified on routine chest and abdominal CT images.
回顾了940例患者的胸部和腹部计算机断层扫描（CT），以确定Bochdalek疝的患病率，并评估一种广泛存在的观念，即左侧疝的发生率是右侧疝的九倍以上。在52例患者中发现了60例Bochdalek疝，患病率为6%，这比之前报道的频率高出100倍以上。发现左侧疝的频率约为右侧疝的两倍。Bochdalek疝在无症状成年人中是一种比之前认为的更为常见的先天性异常，并且经常可以在常规胸部和腹部CT图像上识别出来。
