A 42-year-old woman with large aortic aneurysm and psoas abscess.. A. Contrast-enhanced CT shows the characteristic appearance of mycotic aneurysm with thick inflammatory mantle and anterior displacement of abdominal aorta.. B. Stent graft consisting of three segments of Z-stent covered with polytetrafluoroethylene, and fenestrated to secure flow along the celiac axis (arrow).. C. One-year follow-up after stent graft. Abdominal CT shows successfully occluded tuberculous aneurysm and complete healing of psoas abscess.

There was associated destruction of adjacent vertebrae (Fig. 1A). The stent consisted of three Z-segments covered with expanded polytetrafluoroethylene (Taewoong Medical, Seoul, Korea) and with the upper one-third partially fenestrated to ensure flow along the celiac axis (Fig. 1B). Although the stent graft was placed in an inflamed aorta, neither CT (Fig. 1C) nor two-year clinical evaluation revealed complications such as prosthetic infection, tuberculous bacteremia, the recurrence of the psoas abscess or aortitis, or aneurysmal rupture.

A 41-year-old man with rupture of aortic aneurysm during surgery for drainage of psoas abscess.. A. Pre-operative enhanced CT shows psoas abscess with a small aneurysm of the aorta (arrow).. B. Three months after stent graft deployment, the myocotic aneurysm was occluded and the psoas abscess had completely healed.

Chest radiographic finding were normal, but abdominal CT showed an irregular low-attenuation mass, about 3x4x5 cm in size and with rim enhancement, in the left para-aortic region anterior to the left psoas muscle, as well as a small aortic aneurysm (Fig. 2A). After placement of the stent graft, anti-tuberculous medicine (isoniazid, rifampin, and etambutol) was administered, and follow-up CT three months later showed that the aneurysm had completely disappeared and the psoas abscess completely healed (Fig. 2B).
