 | Media file 1: Frontal radiograph of the left fibula head demonstrates a lucent lesion that contains the typical chondroid matrix calcification. Low-grade tumor. |
 | Media file 2: Frontal radiograph of the left acetabulum demonstrates an expansile lucent lesion with no internal matrix calcification. Low-grade central tumor. |
 | Media file 3: Bone-window CT scan of left acetabulum demonstrates matrix calcification in the expansile lucent lesion in the anterior column (see also Images 2, 4, and 5 in Multimedia Section). Low-grade central tumor. |
 | Media file 4: T2-weighted axial MRI of the pelvis demonstrates the high signal intensity of the acetabular lesion (same patient as in Images 2-3, 5 in Multimedia). Low-grade central tumor. |
 | Media file 5: T1-weighted axial MRI of the pelvis demonstrates the low signal intensity of the acetabular lesion (same patient as in Images 2-4 in Multimedia). Low-grade central tumor. |
 | Media file 6: Frontal radiograph of right side of upper abdomen demonstrates a destructive, expansile lesion of the 12th rib. The lesion contains irregular calcification. High-grade central tumor. |
 | Media file 7: CT of the right side of the upper abdomen demonstrates the expansile tumor with a large associated soft tissue mass containing foci of calcification (see also Image 6 in Multimedia Section). High-grade central tumor. |
 | Media file 8: Frontal radiograph of the pelvis demonstrates extensive calcification overlying the left ilium and in the lateral soft tissues. No bone destruction is shown. High-grade secondary peripheral tumor. |
 | Media file 9: CT scan of the pelvis demonstrates a large soft tissue mass that contains calcification arising from a broad-based sessile osteochondroma on the posterior aspect of the ilium (see also Images 8 and 10 in Multimedia Section). High-grade secondary peripheral tumor. |
 | Media file 10: T2-weighted axial MRI of the pelvis demonstrates a lobulated high-signal-intensity soft tissue with local-signal-intensity septa arising from the osteochondroma on the posterior aspect of the ilium (same patient as in Image 9 in Multimedia). Several areas of low signal intensity are shown; these correspond to focal areas of dense calcification. This appearance is typical of cartilaginous material. High-grade secondary peripheral tumor. |
 | Media file 11: Lateral radiograph of the distal femur in a patient with hereditary multiple exostoses. Several osteochondromas of varying appearances arise from the metaphyseal region; these typically grow away from the joint. Soft tissue calcification is shown overlying the most posterior osteochondroma. High-grade secondary peripheral tumor. |
 | Media file 12: CT scan of the distal femur demonstrates a broad-based osteochondroma with a thick overlying soft tissue cap that contains focal calcification. The metaphyseal contour is irregular because of the presence of several other osteochondromas in this patient with hereditary multiple exostoses (see also Images 11 and 13 in Multimedia Section). High-grade secondary peripheral tumor. |
 | Media file 13: Fast spin-echo T2-weighted axial MRI of the distal femur in a patient with hereditary multiple exostoses (same patient as in Images 11-12 in Multimedia). Image demonstrates the thick cartilage cap overlying a broad-based osteochondroma. Areas of focal reduced signal intensity in the cartilage cap correspond to foci of dense calcification. High-grade secondary peripheral tumor. |
