One year later, computed tomography revealed a saccular abdominal aortic aneurysm with extensive periaortic inflammation and an iliopsoas abscess. Polymerase chain reaction analysis confirmed\n \n Mycobacterium bovis<\/jats:italic>\n <\/jats:styled-content>\n BCG infection. Despite antituberculosis therapy, aneurysmal rupture with abscess progression occurred, necessitating prosthetic graft replacement with omental flap coverage. The patient recovered without recurrence after prolonged therapy.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n BCG\u2010related infectious aortic aneurysm may develop even in the absence of fever or marked inflammatory response. Clinicians should suspect and consider early CT evaluation in patients with a history of intravesical BCG therapy when unexplained retroperitoneal or vascular abnormalities are identified, regardless
