CTICasesTraumatic Diaphragmatic Hernia from Penetrating Stab Wound
Imaging findings
Chest CT in a patient with a penetrating stab wound demonstrates an eight-centimeter defect in the left hemidiaphragm with intrathoracic herniation of the spleen, stomach, colon, and omental fat, accompanied by a thickened, curled, and retracted edge of the ruptured diaphragmatic muscle.
Key takeaways
Penetrating diaphragmatic injuries from knife wounds can lead to disproportionately large tears because the diaphragm is under constant muscular tension and respiratory motion, which causes the torn edges to pull apart and retract. Immediate surgical repair is required to avoid progressive herniation, bowel incarceration, or strangulation.
