Isolated periaortitis

Case contributed by Dr Erik Ranschaert

Presentation

48-year old patient was referred by GP for microscopic hematuria and flank pain.

Patient Data

Age: 48
Gender: Male
Ultrasound

Abdominal ultrasound

A thick hypoechoic rim was found around the atherosclerotic wall of the abdominal aorta. To exclude a dissection or other vascular pathology an CTA of the abdominal aorta was ordered and performed.

CT

CT Abdomen and pelvis

CTA in the arterial and delayed phase confirm the presence of a soft tissue rim around the abdominal aorta, which is mildly enhancing. A dissection could be excluded. These findings correspond with a so-called isolated periaortitis, which is a non-aneurysmal form of an inflammatory abdominal aortic aneurysm.

Case Discussion

Chronic periaortitis (also called inflammatory abdominal aortic aneurysm) is an inflammatory condition which typically involves the infrarenal portion of the abdominal aorta. Isolated periaortitis is the non-aneurysmal form of the same entity. An exaggerated inflammatory response due to advanced atherosclerosis is thought to be the main pathogenic process. Autoimmunity has been proposed as a contributing factor.
