Figure 2

A Plain radiograph of the left shoulder showing a lytic lesion affecting the proximal humerus, with cortical irregularity medially (arrow), that was not initially recognized. B At the time of arthrographic distension, the lesion (arrow) was more apparent, but remained unnoticed. C Sagittal TSE post-contrast MR image showing an enhancing lesion within the proximal humerus extending outside the bone. D Axial TSE post-contrast MR image showing the tumour destroying the humeral head and extending into the gleno-humeral articulation. 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 proximal humerus at 4 hrs. Histological sections from the biopsy and surgical resection specimen were consistent with a malignant fibrous histiocytoma.
