CTICasesIncarcerated diaphragmatic liver hernia
Imaging findings
Chest radiograph shows a right-sided whiteout with rib/clavicle fixation plates. CT and coronal reconstructions show herniation of the right liver lobe and transverse colon through a diaphragmatic defect, with a collar-like waist (dependent viscera sign) causing pressure necrosis and biliary obstruction.
Key takeaways
Traumatic diaphragmatic ruptures can remain asymptomatic for decades before presenting with delayed visceral herniation and incarceration. Compression of the liver at the hernia neck can cause ischemic pressure necrosis and biliary tract obstruction.
