57-year-old female with sacral decubitus ulcer and osteomyelitis on MRI, There is osteolysis and destruction of the bilateral ischium and sacrum corresponding to osteomyelitis from large sacral decubitus ulcer on MRI. There is additional destruction of the left femoral neck with an intertrochanteric fracture. Extensive heterotopic bone surrounds the left femoral neck suggesting a somewhat chronic component. The proximal femoral diaphysis is mildly proximally and laterally displaced relative to the femoral head, which articulates with the acetabulum. The proximal femoral diaphysis demonstrates cortical thickening and irregularity, likely due to chronic osteomyelitis.There is an additional fracture of the pubic bone. Mild osteoarthritic changes affect the right hip. The left lower extremity is demineralized with mild osteoarthritic changes of the left knee.
Extensive destruction and osteolysis due to osteomyelitis involving the bilateral ischium, sacrum and left femoral neck with superimposed left femoral neck intertrochanteric fracture and left pubis fracture.
