Figure 3

A Initial plain radiographs of the shoulder were unremarkable. B Repeat radiographs after two years of failed treatment, showing an irregular mixed lytic and sclerotic lesion destroying the coracoid process of the scapula (arrow), which was not appreciated. C Arthrogram performed prior to hydrodilatation similarly showing the destructive process, which remained unnoticed. D Axial T1-weighted post-contrast MR image showing a heterogenous contrast-enhancing lesion destroying the glenoid and extending into the gleno-humeral joint. The lesion is lobulated and loculated with central areas of lower signal intensity, suggestive of a chondroid lesion. E Bone scan showing increased uptake in the area of the lesion on the delayed static image. F Thallium functional scanning showing no retention of thallium by the lesion at 4 hrs. Biopsy confirmed low-grade chondrosarcoma.
