 | Media file 1: Plain radiograph of the cervical spine shows a solitary osteochondroma of the posterior elements of C6. |
 | Media file 2: Radiographs of both hands of 36-year-old man show multiple osteochondromas involving the radii right distal fibula, metacarpals, and phalanges. Note the large osteochondroma involving the terminal phalanx of the right index finger. |
 | Media file 3: Plain radiograph of the pelvis in a 41-year-old woman shows multiple osteochondromas affecting the left transverse process of L5, the iliac blades, the superior pubic rami, the ischial spines, and the femoral necks. Note the modeling deformity of the femoral necks and the narrowing of the pelvic inlet as a result of osteochondromas. Several reports have described osteochondromas interfering with normal vaginal birth in pregnancy and leading to a higher rate of Cesarean deliveries. |
 | Media file 4: Multiple osteochondromatosis. Plain radiograph of the lower limbs of a 10-year-old boy with a family history of hereditary multiple exostoses shows widening of the lower femoral metaphyses and osteochondroma involving the upper fibulae and tibia. |
 | Media file 5: Solitary osteochondroma. Radiograph of 24-year-old woman who presented with a hard, palpable mass on the medial aspect of the upper calf. A bulbous, pedunculated osteochondroma arising from the medial side of the upper tibial diaphysis and pointing away from the metaphysis is noted. The patient reported no history of hereditary multiple exostoses. |
 | Media file 6: Multiple osteochondromatosis. Fractures of the lower tibia and fibula as a complication of hereditary multiple exostoses. Note the osteochondromas involving the calcaneum and the upper and lower portions of the tibia and fibula. |
 | Media file 7: Multiple osteochondromatosis. Radiograph of the pelvis in a 28-year-old woman known to have hereditary multiple exostoses who presented with a painful swelling of the left buttock. Note the multiple osteochondromas and fragmentation of the osteochondroma arising from the left anterior iliac crest (see Image 8 in Multimedia). |
 | Media file 8: Multiple osteochondromatosis. Nonenhanced, axial computed tomography (CT) scan through the pelvis (same patient as in Image 7 in Multimedia). Note the fragmentation of the osteochondroma and the considerable soft-tissue mass. Histology of the resected specimen revealed a low-grade chondrosarcoma. |
 | Media file 9: Osteochondroma with malignant degeneration. Plain radiograph of the pelvis in a 68-year-old woman who presented with a painful lump over the left greater trochanter. Note the sclerotic exostosis arising from the left greater trochanter. Technetium-99m (99mTc) diphosphonate scintigram (left) shows intense activity in the region of the left greater trochanter. At surgery (right), the lesion was diagnosed as a low-grade chondrosarcoma superimposed on an osteochondroma. |
