CTICasesIatrogenic Diaphragmatic Hernia
Imaging findings
Post-operative development of a right-sided hernia following a partial hepatectomy. The hernia contained distended, obstructed colon showing the "collar sign" on sagittal imaging.
Key takeaways
Partial hepatectomy can alter the anatomy that previously prevented abdominal organs from reaching the diaphragm; a small iatrogenic nick in the diaphragm can allow compliant fat to migrate under abdominal pressure, leading to serious obstruction.
