Bochdalek hernia

Case contributed by Charlie Chia-Tsong Hsu
Diagnosis certain

Patient Data

Age: Adult
Gender: Female
ct

CT thorax coronal view demonstrates a right Bochdalek hernia. There is herniation of peritoneal fat through a congenital diaphragmatic defect, Bochdalek foramen, in the posterolateral right hemidiaphragm. Bochdalek hernia is usually left sided and maybe an incidental finding in as high as 10% of asymptomatic adult 1. As demonstrated in this case, the herniation content is usually retroperitoneal fat and less often kidney (right sided).

x-ray

Anteroposterior chest radiograph shows double density of right hemidiaphragm. A rounded curvilinear structure (white arrow) is projected above the true right hemidiaphragm (black arrow). This rounded curvilinear structure appears to be of fat density. 

Lateral chest radiograph shows three curvilinear densities. Blue arrow points to the right hemidiaphragm, red arrow points to the left hemidiaphragm and black arrow points to a third curvilinear structure projected above and silhouetting the posterior right hemidiaphragm.
