Melorheostosis is a bone dysplasia with sclerotic foci, typically described as flowing candle wax. Fibrous dysplasia has varied manifestations and can affect a single bone or multiple bones. It can demonstrate ground glass appearance, lucency or sclerosis. Lead poisoning may demonstrate metaphyseal bands as well as the bone-in-bone appearance. In pyknodysostosis there is generalised increased density of the long bones; however the medullary cavity is spared, unlike in osteopetrosis.

Melorheostosis is a very rare non-hereditary disease of unknown aetiology. Patients can present with pain and restricted movements of the joint, but the disease is usually asymptomatic and is discovered incidentally. Some patients may have thickening and fibrosis of overlying skin, resembling scleroderma or joint contractures. Radiographic features include dense irregular bone running down the cortex of a tubular long bone, which can cross the joint. This has the appearance of flowing/molten wax and is usually limited to one side of cortex, although the internal or external cortex may be affected. The lower limbs are the most commonly affected. Other notable features are discrepant leg length on the affected side and the presence of adjacent ossified soft-tissue masses (27%).

Melorheostosis is rare sclerosing bone dysplasia presenting as localised, diffuse thickening of the cortical bone, and rarely affecting the craniofacial complex [19,42–46]. Paget’s disease is a disorder of bone remodelling with bone resorption, followed by an increase in disorganized bone formation [47]. Radiographically, Paget’s disease features several stages, most of which are mixed or radiopaque [47]. Hybrid-CGCG lesion with melorheostosis or Paget’s created a unique multilocular radiolucency within the thickened and sclerotic bone. It appears that CGCG cannot ‘camouflage’ its appearance radiographically when coexisting with a radiopaque entity such as FD, Paget’s, or melorheostosis.
