The typical appearance of bone involvement

The typical appearance of bone involvement by these lesions on radiographs is a focal, well-defined, lucent lesion surrounded by irregular, coarse, thickened trabeculae. Abnormal vascular spaces infiltrate and replace the bone and are surrounded by irregular, reactively thickened trabeculae. Any part of the skeleton may be affected, but most of these lesions are found in the vertebral bodies, where the thickened trabeculae are vertically oriented and give the lesion a “corduroy” appearance.
