CTICasesGiant Traumatic Diaphragmatic Hernia
Imaging findings
CT in an adult male with a history of a crash 20 years prior demonstrates a massive right-sided diaphragmatic hernia containing the liver, stomach, and bowel loops in the chest, causing significant mass effect, mediastinal shift, and chronic right lung collapse (dangling diaphragm sign).
Key takeaways
Traumatic diaphragmatic hernias can remain unrecognized for decades following a motor vehicle crash or blunt trauma. They can grow progressively, leading to massive intrathoracic displacement of abdominal contents and chronic compressive atelectasis.
