Traumatic diaphragmatic hernia into the pericardium: verification of diagnosis by computed tomography.

Computed tomography (CT) is a useful modality in the evaluation of mediastinal abnormalities and in the assessment of mediastinal masses for fat content. A case of posttraumatic herniation of the omentum and large bowel into the pericardial sac is presented. The mediastinal configuration, depicted on a CT scan, is thought to be diagnostic of this extremely rare abnormality.
