(a) Radiograph of the pelvis AP view; (b) 3D reconstruction and (c) axial section of CT showing expansile lytic lesion involving the right sacral ala with cortical break and surrounding soft-tissue component extending into right SI joint space and pelvis measuring  cm eroding the adjacent iliac bone. Mass extending into the sacral canal. (d) MRI showing large expansile heterogeneous lobulated lesion with few septations involving right sacroiliac joint. Predominantly lytic lesion with cortical destruction features suggestive of GCT.
