CTICasesBochdalek Hernia
Imaging findings
CT shows a large posterior diaphragmatic defect with herniation of retroperitoneal fat and a large portion of the colon (specifically the hepatic flexure) into the posterior chest cavity, beautifully demonstrated on sagittal reformatted imaging.
Key takeaways
Bochdalek hernias are congenital diaphragmatic hernias resulting from improper closure of the posterolateral diaphragmatic membrane. Although most are small and contain only fat, larger hernias can contain retroperitoneal organs or bowel segments and may present incidentally in adults.
