Table 2 Specific radiological features dependent on body site [10]
Bone | Features |
|---|---|
Pelvis and ribs | • Fibrous dysplasia is the most common cause of a benign expansile lesion of a rib. • Expansile lytic lesion • Fusiform enlargement of the rib • Minor calcifications within the lesion may be seen |
Extremities | • Bowing deformity, in particular of the large weight-bearing bones (e.g. shepherds crook deformity of the proximal • femur) • Looser zones • Co-existent precocious puberty may lead to premature fusion of growth plates resulting in short stature |
Skull and craniofacial bones | • Bone expansion showing ground-glass appearance • Calvarial deformity resulting in exophthalmos |
