 | Media file 1: Plain radiograph of the distal femoral epiphysis in a 12-year-old boy. This image shows a chondroblastoma with a characteristically lucent lesion and well-defined margins. Extension across the physis was confirmed with computed tomography scanning and magnetic resonance imaging (see Images 2-4). |
 | Media file 2: Coronal reconstructed computed tomography scan of the knee in a 12-year-old boy (same patient as in Images 1, 3-4). This image confirms extension of the chondroblastoma into the metaphysis. |
 | Media file 3: Coronal T1-weighted magnetic resonance image of the knee (same patient as in Images 1-2, and 4). This image also confirms extension of the chondroblastoma into the metaphysis. |
 | Media file 4: Sagittal T2-weighted magnetic resonance image of the knee (same patient as in Images 1-3). This image shows extension of the chondroblastoma across the physis. At histologic examination, central foci of low signal intensity, which are common in chondroblastomas, may be correlated with hypercellularity of the chondroblasts, calcification, and/or hemosiderin deposition. |
 | Media file 5: Plain radiograph of the proximal tibia in a 14-year-old boy. This image demonstrates a chondroblastoma that has well-circumscribed, thin, sclerotic margins. Chondroblastomas may have sclerotic, nonsclerotic, or incompletely sclerotic borders. |
 | Media file 6: Coronal T1-weighted magnetic resonance image of a proximal tibial chondroblastoma (same patient as in Images 5 and 7). |
 | Media file 7: Coronal T2-weighted magnetic resonance image (MRI) of a proximal tibial chondroblastoma (same patient as in Images 5-6). The lesion is confined to the epiphysis. The presence of surrounding edema is best depicted with MRI. |
 | Media file 8: Plain radiograph of the greater trochanter in a 24-year-old man. Chondroblastomas that occur in the proximal femur are 3 times more likely to occur in the greater trochanter than in the femoral head. |
 | Media file 9: Coronal T2-weighted magnetic resonance image of a greater trochanter chondroblastoma (same patient as in Image 8). |
 | Media file 10: Plain radiograph of the right upper extremity of a 16-year-old girl. This image shows a chondroblastoma in the humeral head (see Images 11-12). |
 | Media file 11: Axial computed tomography scan of a humeral head chondroblastoma (same patient as in Images 10 and 12). The mottled central opacity that was demonstrated on the plain radiograph was due to amorphous calcifications within the lesion, which occur in approximately 60% of all chondroblastomas. |
 | Media file 12: Bone scan of a humeral head chondroblastoma (same patient as in Images 10-11). Uptake of the bone-seeking agent may be due in part to the regional hyperemia of the tumor. |
 | Media file 13: Plain radiograph of the talus in a 12-year-old boy. About 10% of all chondroblastomas occur in the small bones of the hands and feet. The talus and calcaneus are relatively common sites. |
 | Media file 14: Plain radiograph of the pedicle and transverse process of a lumbar vertebra. Although the diagnosis of osteoblastoma was made on the basis of the radiographic appearance of the tumor, chondroblastoma was confirmed at pathologic examination. |
 | Media file 15: Axial computed tomography scan of a spinal chondroblastoma (same patient as in Images 14, 16-17). Chondroblastoma rarely occurs in the spine. |
 | Media file 16: Axial nonenhanced T1-weighted magnetic resonance image of a spinal chondroblastoma (same patient as in Images 14-15 and 17). |
 | Media file 17: Contrast-enhanced axial T1-weighted magnetic resonance image of a spinal chondroblastoma (same patient as in Images 14-16). This image shows nonspecific but uniform enhancement throughout the lesion. |
 | Media file 18: Oblique plain radiograph of the patella in a 16-year-old girl. Note the presence of a comminuted pathologic fracture in association with the chondroblastoma. |
 | Media file 19: Axial computed tomography scan of a patellar chondroblastoma (same patient as in Image 18). This image shows the comminuted pathologic fracture to better advantage. |
 | Media file 20: Plain radiograph of the acromion in a 54-year-old man. The chondroblastoma is in an unusual location and is atypically present in an older patient. |
 | Media file 21: Plain radiograph of the proximal humerus in a 17-year-old boy. A subtle, solid, adjacent metaphyseal periosteal reaction is present medially due to the chondroblastoma. A metaphyseal periosteal reaction occurs in 15-30% of chondroblastomas. |
 | Media file 22: Axial T2-weighted magnetic resonance image of a humeral head chondroblastoma (same patient as in Images 21 and 23). Fluid-fluid levels are occasionally seen on images of chondroblastomas, which can simulate aneurysmal bone cysts. |
 | Media file 23: Bone scan of a proximal humeral chondroblastoma (same patient as in Images 21-22). In the presence of a periosteal reaction, uptake of the bone-seeking agent may extend beyond the lesion's margins. |
