(a and b) Radiographs demonstrating an expansive multiloculated osteolytic lesion involving the femur, causing a "wine fiasco" bone deformity. The lesion did not spread beyond the growth plate, and no fractures were present.

Thinning and irregularity of the cortical bone were present (Fig. 1).
(a) Coronal TSE T1 image showing a lesion in the femur, characterised by a low intensity, non-homogeneous signal. (b) Axial TSE T2 and (c) coronal STIR images demonstrating an expansive mass with large cavities with fluid-fluid levels. (d) Following administration of gadolinium, coronal T1 SPIR showed slight enhancement of the septa, with no signs of infiltration of adjacent tissues.

After administration of a paramagnetic endovenous contrast agent (gadoterate meglumine), only a slight rim of septa enhancement was revealed, with no signs of infiltration of adjacent tissues (Fig. 2).
(a) Radiograph showing an osteolytic lesion of the left zygomatic bone in which context fracture line and bone restructuring can be observed. (b) Coronal TSE T2 FS image demonstrating a large lesion causing cortical erosion and infiltration of the adjacent soft tissues. (c) Following administration of gadolinium, coronal T1 FS images revealed strong, non-homogeneous enhancement of the lesion, and oedema and enhancement of soft tissue can also be observed.

Radiological staging of the other bone compartments was then performed, which revealed a single osteolytic lesion of the left zygomatic bone (Fig. 3).
