Coronal T2 DIXON reconstructions demonstrating diffuse signal changes in the bone marrow (T2 hyperintensity with loss of fat signal on DIXON fat reconstruction), consistent with glyogen storage disease and a history of G-CSF use. Axial PD and axial T2 DIXON water reconstructions demonstrate the same.
Furthermore the MR demonstrates findings consistant with left sacro-iliac arthritis, with joint effusion, juxta-articular bone marrow edema en peri-articular swelling and edema.
