CTICasesDiaphragmatic Eventration with Retroperitoneal Liposarcoma
Imaging findings
Abrupt transition from normal to elevated right hemidiaphragm; normal muscle thickness anteriorly and posteriorly; large retroperitoneal mass (likely liposarcoma) pushing on the diaphragm.
Key takeaways
An abrupt, non-tapering transition to an elevated diaphragm is characteristic of eventration rather than paralysis, as the posterior muscle attachment remains intact.
