Bilateral psoas abscesses extending to the gluteal muscle and intrapelvic area are uncommon. We present our experience with computed tomography (CT)-guided percutaneous catheter drainage for the treatment of multiple aggressive abscesses in a diabetic patient. The abscesses completely resolved after the procedures. Psoas abscess should be considered in the differential diagnosis of older diabet...
