  • Title: Mycotic aneurysms of the aorta: radiologic features.
    Author: Gonda RL, Gutierrez OH, Azodo MV.
    Journal: Radiology; 1988 Aug; 168(2):343-6. PubMed ID: 3260676.
    Abstract:
    Four patients with a total of six mycotic aneurysms of the aorta were examined with computed tomography (CT) after intravenous contrast material enhancement, and with abdominal or thoracic aortography. In the three patients with mycotic aneurysms involving the abdominal aorta, CT scans showed a vascular paraaortic structure without calcified walls adjacent to a nondilated aorta, and a large non-contrast-enhanced retroperitoneal mass representing inflammatory tissue and blood from a contained aortic rupture. A CT scan of one aneurysm of the thoracic aorta demonstrated an enhanced saccular mass originating from the aorta without paraspinal component. In three of four patients, the CT findings were corroborated by aortographic evidence of an eccentric aneurysmal sac in an atypical location for atheromatous disease. In four patients with clinical manifestations suggesting mycotic aneurysm of the aorta, a combination of CT and angiographic imaging provided accurate diagnostic information for planning adequate and early surgical treatment.
