We report herein a case successful endovascular treatment with a stent-graft of a rare case of rapidly growing mycotic aneurysm of the left common carotid artery due to acute bacterial endocarditis after eradication of the infection. Infected mycotic aneurysms of the peripheral vasculature have been considered as a contraindication for stent-graft implantation because of the possibility of microorganism spreading to the stent-graft; however, if there is evidence of complete eradication of microorganism and surgery is not an option, stent-graft implantation can be an effective and safe treatment modality for exclusion of the mycotic aneurysm.

Although pulmonary artery aneurysms are a rare vascular anomaly, they are seen in a wide variety of conditions, such as congenital heart disease, infection, trauma, pulmonary hypertension, cystic medial necrosis and generalized vasculitis. To our knowledge, mycotic aneurysms caused by pulmonary actinomycosis have not been reported in the radiologic literature. Herein, a case of pulmonary actinomycosis complicated by mycotic aneurysm is presented. On CT scans, this case showed focal aneurysmal dilatation of a peripheral pulmonary artery within necrotizing pneumonia of the right lower lobe, which was successfully treated with transcatheter embolization using wire coils.
