Positron emission tomography (PET) CT imaging was pursued for further evaluation of the intra-abdominal lymphadenopathy and revealed increased radiotracer activity and soft tissue stranding at the bifurcation of the aortoiliac stent, indicative of increased metabolic activity (Figure 1).

On a subsequent admission two months later, he was noted to have developed psoas abscesses bilaterally (left 1.9 x 1.8 x 4 cm and right 1.9 x 2.5 x 6 cm) (Figure 2) with aortitis of the posterior aspect of the aorta at the level of L2 and osteomyelitis of L2 and L3 vertebral bodies (Figure 3).
Axial IV contrast-enhanced CT with a small erosion of L2 (red arrow) consistent with osteomyelitis, adjacent to the right psoas abscess (yellow arrowhead).
