Abstract

Mycotic aneurysms are rare and if left untreated, can have devastating outcomes. In this case, a 72-year-old man presented to hospital with fevers, night sweats and abdominal pain. A CT scan revealed the development an infrarenal pseudoaneurysm over the course of 8 weeks, increasing from 2.8 cm to a 3.1 cm. The aneurysm was not present on a CT scan performed 6 months earlier. The patient underwent an emergency endovascular repair of the aortic aneurysm (EVAR) and was placed on broad-spectrum antibiotics. Intra-aortic blood cultures aspirated adjacent to the aneurysm and tissue biopsy confirmed tuberculosis bovis as the cause of the mycotic aneurysm. The patient had been treated with intravesical BCG for transitional cell carcinoma of the bladder several months prior. The patient was treated with an extended course of antituberculosis medication. He recovered well and was back to his baseline function within weeks.
