Case contributed by Dr Charlie Chia-Tsong Hsu


Status post EVAR.

Patient Data

Age: 56
Gender: Male

Dual-Energy CT (DECT) aortogram study in a patient with recent endovascular aneurysm repair (EVAR) for an abdominal aortic aneurysm (AAA).

Reconstituted conventional CT angiogram images (Figure A and B) shows hyperdense material in the right posterolateral aspect of the excluded aneurysm sac (arrow) which is in close proximity to the origin of a left lumbar artery (arrow head)

Post processing DECT virtual contrast/iodine overlay images clearly depict orange colored area in the excluded aneurysm sac confirming with certainty the presence of a type II endoleak.

DECT performed on the Siemens SOMATOM Definition Flash scanner.  Credit to Jit Pratap, chief radiographer, for assistance in post processing of the data.
