a and b are DR anteroposterior and lateral radiographs. Low density shadow can be seen in the scapular area with a clear boundary and a sclerosing zone on part of the edge. c and d show irregular and cystic bone destruction of CT, scapular spine and scapular neck in cross-sectional and sagittal position, respectively, and the bone cortex is punctured before and after perforation. e and f show three-dimensional reconstruction of the CT scapula, showing severe destruction of the scapula, especially the scapular bone, and penetrating the anterior and posterior bone cortex. g and h are T2 images of MRI, showing patchy abnormally high signal and lobulated images
