Imaging findings
A patient with a pacemaker showed atelectasis in the lung bases and a second interface on the radiograph, which was particularly clear on the lateral view, suggesting a posterior mass or hernia. CT revealed a large posterolateral diaphragmatic hernia (Bochdalek-type) containing an entire kidney and a portion of the colon within the chest. Pleural plaques were also present. The radiograph and CT images corresponded, confirming the intrathoracic kidney.
Key takeaways
Bochdalek hernias are developmental posterolateral diaphragmatic defects that typically contain fat or small bowel loops. However, they can occasionally be quite large, allowing for herniation of entire organs such as a kidney or colon into the chest. Careful evaluation of the diaphragm and its contents is essential to identify the herniated structures and avoid misdiagnosis.
