A 76-year-old man was admitted to our hospital for investigation of an apparent abdominal aortic aneurysm detected during treatment for epididymitis. A chest X-ray showed miliary shadows in the bilateral lung fields strongly suggestive of tuberculosis. The diameter of the aneurysm increased, and examinations showed impending rupture of a pseudoaneurysm. However, a definitive disease pathogenesis was not obtained before surgery. We performed a subemergency operation, which revealed an infrarenal abdominal pseudoaneurysm caused by tuberculosis. The pseudoaneurysm appeared to have resulted from direct extension of tuberculous lymphadenitis to the aortic wall, which ruptured. We review 24 other cases of tuberculous aortic aneurysms surgically treated in Japan before 2004.

Miliary tuberculosis refers to the clinical disease resulting from the hematogenous dissemination of Mycobacterium tuberculosis. A tuberculous aneurysm of the aorta is exceedingly rare. Contiguous tuberculosis in the form of lymphadenitis is generally responsible for the aortic involvement. We report a case of tuberculous mycotic aneurysm in patient with miliary disease, not affected by a cellular immunodeficiency and with no other common risk factor for infection. He received anti-tubercular therapy and endovascular stenting before the identification of Mycobacterium tuberculosis in lung, lymph nodes, and gastric lavage. The clinician should be aware that a mycotic abdominal aortic aneurysm could be caused by M. tuberculosis, even if microbiological confirmation is lacking or is negative, especially if a contiguous focus of tubercular infection is detected.
