Mycotic aneurysm of the left subclavian artery: CT findings

Mycotic aneurysms caused by aspergillosis are rare. We report a nine-year-old girl with acute lymphoblastic leukaemia who had invasive pulmonary aspergillosis and subsequently developed a left subclavian artery aneurysm. Prior to the aneurysm, computed tomography (CT) of the chest showed a nodule wi...

Prior to the aneurysm, computed tomography (CT) of the chest showed a nodule with an air crescent in the left upper lobe, adhering to the mediastinum and the left subclavian artery. The left subclavian artery was ill-defined and had a small lumen, and it was embedded in the wall of the nodule. 37 days after the chest CT, the patient underwent a left thoracotomy because of massive haemoptysis, at which time a false aneurysm in the left subclavian artery was found.
