Figure 1.

A 68-year–old woman who underwent work-up for fever of unknown origin. 18FDG-PET/CT: maximum intensity projection (MIP) (a) and representative PET (b) and CT (c) axial slices. PET demonstrates increased uptake in the non-homogeneous soft tissue paravertebral mass with intrathecal infiltration (curser). Additional foci of increased uptake in the pleural/extra pleural lesion appear in the inner chest wall on the right (arrow). Findings are consistent with a paravertebral abscess and septic emboli.
