meative lesion has a greater than 80% likeli-hood of malignancy [9]. Lesion matrix can help recognize prima-ry cartilaginous, osseous, or fibrous bone tu-mors [8]. This mineralized matrix may be quite difficult to recognize at MRI. The dif-ferential considerations for a bone lesion will be based on the aggressiveness of the lesion

cent lesion usually located in the metaphyse-al area and commonly invading the epiphysis (Fig. 4A). Expansile remodeling results in a soap-bubble or blown-out appearance. The cortex may be thinned or destroyed with asso - ciated soft-tissue masses. The margins of the lesion are variable, ranging from sclerotic to poorly defined [16].

There is a variable degree of internal mineralization, and the lesion can appear locally aggressive with cortical destruction and soft tissue exten-sion (despite its benign nature). On MRI, the lesion has low to intermediate signal on T1- and T2-weighted images,

(OS-tee-oh-lit-ik) or lytic (LIT-ik) lesions. Lytic lesions are so weak that they can cause the bone to easily break. Sometimes, the cancer cells release substances that turn on the osteoblasts. This leads to new bone being made without breaking down the old bone broken down first. This makes areas of the bones harder, a condition called ...
