The prevalence of pancreatic incidentalomas in patients undergoing surveillance for abdominal aortic aneurysms

Serial imaging in patients with aortic aneurysms may identify non-vascular disease. However, the prevalence and clinical history of pancreatic incidentalomas in this population is unknown.

Retrospective cross-sectional study of adults who underwent computed tomography angiography (CTA) surveillance imaging for abdominal or thoracoabdominal aortic aneurysm at a single academic institution between 2015 and 2020. Descriptive statistics were used for patients with pancreatic lesions.

Of 249 patients, 18 (7.2 %) had a pancreatic incidentaloma. Compared to patients without a lesion, those with a lesion were more likely female (50.0 % vs 24.2 %, p = 0.02) and less likely a smoker (72.2 % vs 90.0 %, p = 0.02). 3 patients with pancreatic lesions underwent intervention, and 1 patient received additional imaging. 2 patients had a surgical oncology referral.

Pancreatic incidentalomas are common in patients with aortic aneurysm, but lesion characteristics and management vary. Results suggest that a multi-disciplinary approach, thorough documentation, and referral to pancreatic specialists may be warranted.
