Mycotic Pseudoaneurysms of the aorta are rare pathologic units accounting for 0.7 to 1.3% of infectious aneurysms of the aorta. Bacterial agents are the most frequently involved, while fungal agents are rare, occurring in areas of immunosuppression. The radiological diagnosis is essentially based on the five CT signs: the presence of the aneurysm sac, inflammation of the periaortic spaces, the absence of thrombi and aneurysmal wall calcifications and rapid growth. The main complication is aortic rupture with septic and hemorrhagic shock.
