Abnormal bone fiber proliferation, hereafter referred to as osteochondrosis, is a common abnormal bone developmental disease, sometimes classified as a neoplastic lesion of bone. Bone fibrils can occur in any bone throughout the body and can be solitary or multiple. The underlying pathologic changes are very similar in different bones and therefore the imaging presentation is also similar. Among the many imaging methods, radiographs are the most important and indispensable, and the general diagnosis of long bone fibers can be made on the basis of radiographs, and their manifestations are very different from those of infectious bone diseases or osteogenic tumors, without the need for CT, MRI, or even PET-CT.
