title: Multiple 18F-Fluorodeoxyglucose Positron Emission Tomography Scans Showing Progression of Abdominal Aortic Aneurysm: A Case Report.
abstract: Although the precise mechanisms underlying the pathogenesis of abdominal aortic aneurysm (AAA) remain unclear, aortic wall inflammation has been implicated in AAA development. Several studies have reported the use of fluoro-deoxyglucose (F-FDG)/positron emission tomography (PET) to assess the nature of AAA.We present a case of 77-year-old Japanese male with juxta-anastomotic AAA who was followed up with multiple F-FDG-PET/CT scans over 7 years. The scans revealed chronological changes in aortic wall inflammation leading to progress and eventual rupture.This case supports a notion that aortic wall inflammation plays a role in AAA progression and rupture.
