Salmonella-induced mycotic pseudoaneurysm of the right common iliac artery

Mycotic pseudoaneurysms are rare vascular abnormalities caused by infections, often leading to high rates of morbidity and mortality. Mycotic pseudoaneurysms are most commonly present in the aorta and femoral arteries, but a small number are observed in the common iliac artery. Here, we report the unusual instance of a <i>Salmonella</i>-induced mycotic pseudoaneurysm in the right common iliac artery of a 73-year-old male. Traditional imaging modalities supplemented with novel postprocessing techniques like 3D cinematic rendering enabled more confidence in differentiating between true aneurysms and pseudoaneurysms while providing a better anatomical view for preoperative planning. This case underscores the rarity of <i>Salmonella</i>-induced mycotic pseudoaneurysms and emphasizes the importance of early diagnosis using advanced imaging (CT, CTA with 3D cinematic rendering) and a multidisciplinary approach to treatment, which includes both infection management and surgical repair.
