Ruptured Aortic Aneurysm Secondary to Psoas abscess after Intravesical Bacilli Calmette-Guérin

Med J Malaysia. 2012 Oct;67(5):534-5.


Bacillus Calmette-Guérin (BCG) is a live attenuated strain of Mycobacterium bovis that has been used as effective treatment for early-stage transitional carcinoma of the urinary bladder. We present a case of a 68 year old man who had an abdominal aortic aneurysm following BCG therapy for bladder cancer. Contrast enhanced computerized tomogram (CECT) of abdomen and pelvis revealed bilateral hypodense lesions suggestive of psoas abscesses. In addition, a saccular abdominal aortic aneurysm measuring 4x3.6 cm involving infrarenal aorta with surrounding hematoma was seen. At surgery, he was found to have a psoas abscess and hemorrhage. He underwent ligation of the aorta and an axillary-bifemoral bypass. He was given one year of anti-tubercular therapy to which he responded clinically.
