The imaging manifestations of osteochondrodysplasia are as follows: single lesions involving the long bones, limited lesions involving the epiphysis, extensive lesions involving one end of the long bones and most of the diaphysis, and multiple lesions involving one limb and several adjacent bones. The lesions are located in the medullary cavity and show osteolytic destruction, in which frosted glass-like and irregular bone textures are seen, with swelling and expansion of bone and thinning of bone cortex without periosteal reaction. The boundary between the lesion and normal bone is clear, the lesion is swollen, and the circumference of the backbone can be twice that of normal bone. CT and MRI showed abnormal growth of bone tissue and bony trabeculae, bony cortical curvature, and increased nuclear magnetic signal.
