A 26-year-old man who sustained multiple trauma and had renal failure secondary to rhabdomyolysis as the result of a motor vehicle accident presented with fever and blood cultures positive for Staphylococcus aureus. Bone and gallium scintigraphy were performed to evaluate sites of skeletal fracture for osteomyelitis. Identified was a focus of soft tissue infection related to the placement of a Gortex® dialysis shunt in the left groin. A Tc-99m RBC blood pool venogram demonstrated a filling defect in the left saphenous vein proximal to the shunt with soft tissue inflammation seen on MRI. An abscess was found at surgery for removal of the shunt.
