Infectious Aortitis with Abdominal Aortic Aneurysm in a 47-Year-Old Female with Systemic Lupus Erythematosus

Figure 3

This is an axial view at the level of L4, demonstrating the saccular aneurysm at its maximal caliber of cm (). An intimal flap is seen along the right lateral aspect of this dilatation. The saccular component of the aneurysm arises from the false lumen and is oriented anterolaterally to the right. No definite perivascular contrast extravasation is appreciated indicating that the point of rupture has likely been walled off. A heterogenous, predominantly hypodense fluid collection exhibiting minimal peripheral enhancement is appreciated at the right retroperitoneum, probably subacute hematoma (arrow).
