Clinically Silent Multi-Territory Aneurysms in Cadavers: A Case Report and Literature Review.

Aneurysms are permanent, focal dilations of vessels that are ≥150% of normal diameter. While single aneurysms are relatively common, the presence of multiple aneurysms in different vascular territories is uncommon, and consolidated discussions of such cases remain limited. We report the case of a 96-year-old male cadaver with extensive but clinically silent aortic aneurysms identified during routine anatomical dissection. A large abdominal tumor was also noted compressing the right renal artery. Additionally, we review published reports of multi-territory aneurysms, which highlight the heterogeneity in patients and presentation types, including genetic disorders that lead to aneurysmal disease. Rupture risk is multifactorial, influenced by size, morphology, multiplicity, growth rate, and thrombus burden. Multi-territory aneurysmal disease, though rare, represents a clinically significant entity that may remain undetected until rupture or incidental discovery. Four domains emerge as central to management: screening, risk factor modification, genetic considerations, and counseling. This cadaveric case illustrates the breadth of aneurysm presentations and reinforces the importance of broad screening strategies in their surveillance. It also highlights the roles of risk reduction, genetic evaluation, and patient-centered counseling in reducing morbidity and mortality from this often silent vascular pathology.
