title: Tuberculous ascending aortic pseudoaneurysm.
abstract: Pseudoaneurysms of the ascending aorta due to infective organisms are a rare but challenging entity with a risk of high morbidity and mortality. Previous cardiac surgery is an attributing factor, but they can present without previous surgical interventions. Various micro-organisms are responsible for this pathology. Tuberculous pseudoaneurysms of the ascending aorta are extremely rare. We report a case of a 25-year old man who presented to us with shortness of breath and recurrent haemoptysis. After preoperative evaluation including clinical and radiological assessment and echocardiography, he underwent successful repair of a pseudoaneurysm of the ascending aorta by excision and replacement of the diseased aorta with a Dacron tube graft using cardiopulmonary bypass. Postoperatively, he was started on antituberculous chemotherapy based on histological findings.
