Hemoptysis Due to a Mycotic Pulmonary Artery Aneurysm in an Injecting Drug User

Abstract

Infected aneurysms of the pulmonary artery are a rare consequence of injected drug use. Hemoptysis of pulmonary arterial origin is also infrequent; however, the mortality is as high as 50%. We report here a case of hemoptysis in an intravenous drug user, caused by a pulmonary artery aneurysm due to septic microemboli, originating from a groin abscess. We highlight the importance of recognizing and treating thromboembolic complications associated with deep venous thrombosis in injecting drug users.

“…Infections causing aneurysms, mycotic aneurysms, are estimated to represent only 1–3% of all arterial aneurysms and are rarely located in pulmonary arteries [2]. Patients may present with dyspnea, chest pain, cough, pulmonary hypertension, right ventricular failure and hemoptysis.…”

“…Patients may present with dyspnea, chest pain, cough, pulmonary hypertension, right ventricular failure and hemoptysis. Hemoptysis is estimated to be present in less than 10% of cases, however, when present the suspicion of a pulmonary aneurysm should be raised [1,2]. The non-specific presentation often causes diagnostic delay resulting in critical progression of the aneurysm.…”
