Figure 1.

A Plain radiograph of the right shoulder, showing an irregular, mixed lytic and sclerotic lesion in the glenoid (arrow), that was not appreciated by the reporting radiologist. B Arthrogram performed prior to hydrodilatation. C Coronal TSE post-contrast MR image, showing a diffusely enhansive scapular lesion extending into the inferior aspect of the gleno-humeral joint. D Axial TSE post-contrast MR image showing diffuse enhancement of the tumour extending on either side of the scapular blade with bony destruction. E Bone scan showing increased uptake in the area of the lesion on the delayed static image. F Thallium functional scanning showing retained thallium activity in the glenoid region at 4 hrs. Subsequent biopsy was consistent with Ewing's sarcoma.
