Multiple overlapping radiolucent medullary lesions in the proximal right tibia meta-diaphyseal region.
Some edges of the complex lesion are well-demarcated, however, others are poorly defined. There is endosteal scalloping and periosteal thickening toward the distal end of the lesion, as well as density in the adjacent medial leg soft tissues, which are indications of an aggressive process.
No pathological fracture.
