 | Media file 1: Lateral radiograph of the foot in a 60-year-old man who presented with a mass on the dorsum of his left foot. The radiograph shows a soft-tissue mass that is anterior to the talus and without obvious underlying bone erosion. Subtle faint calcifications are seen within the mass. |
 | Media file 2: Coronal T1-weighted magnetic resonance image of the foot in a 60-year-old man who presented with a mass on the dorsum of his left foot (same patient as in Images 1 and 3). A rounded, soft-tissue mass is seen eroding the cortex of the superior talus. The mass is predominantly isointense relative to the muscle, with scattered areas of hyperintensity that are consistent with hemorrhage. |
 | Media file 3: Sagittal T2-weighted magnetic resonance image of the foot in a 60-year-old man who presented with a mass on the dorsum of his left foot (same patient as in Images 1-2). The mass shows predominantly high signal intensity that is hyperintense relative to fat. Scattered areas of hypointensity probably represent calcifications. |
 | Media file 4: Anteroposterior radiograph of the hip in a patient who presented with a mass in the region of the left hip. Opaque, masslike calcifications overlying the femoral neck and inferior pubic ramus are seen. |
 | Media file 5: Computed tomography scan of the hip in a patient who presented with a mass in the region of the left hip (same patient as in Image 4). The scan was obtained through the mass and demonstrates masslike areas of calcification within the muscle density in the region of the left obturator externus muscle. |
 | Media file 6: Computed tomography scan through the right thigh. This image demonstrates a round, noncalcified, well-circumscribed mass that displaces, rather than invades, the surrounding muscles. The mass appears to be separate from the bone. |
 | Media file 7: Lateral radiograph of the femur in a 45-year-old man who presented with a large, right midthigh mass. This radiograph is remarkable only for a subtle soft-tissue prominence on the anterior aspect of the thigh. No calcifications are depicted. |
 | Media file 8: Computed tomography scan of the thigh in a 45-year-old man who presented with a large, right midthigh mass (same patient as in Images 7, 9-10). A well-defined mass is seen on the anterior aspect of the thigh and appears to be mostly isodense relative to the muscle, with curvilinear areas of slightly increased density. The mass appears apposed to the underlying bone. |
 | Media file 9: Axial T1-weighted magnetic resonance image of the thigh in a 45-year-old man who presented with a large, right midthigh mass (same patient as in Images 7-8, 10). The anterior mass is well circumscribed, with mostly homogeneous isointensity relative to the muscle. Scattered, small, hyperintense foci probably represent hemorrhage. The fat plane between the mass and the femur is preserved. |
 | Media file 10: Coronal T2-weighted magnetic resonance image of the thigh in a 45-year-old man who presented with a large midthigh mass on the right (same patient as in Images 7-9). On this T2-weighted image, the mass has become markedly heterogeneous, with high signal intensity depicting cystic regions of hemorrhage and necrosis. Note that portions of the mass are hyperintense relative to the subcutaneous fat. The location of the mass is somewhat atypical because it is centered at the level of the midshaft rather than near a joint. |
 | Media file 11: Sagittal T1-weighted magnetic resonance image of the thigh in a patient with a mass in the anterior left upper thigh and/or inguinal region. The image shows large areas of hemorrhage and necrosis, with intermediate signal intensity on a background of a muscle-intensity mass. |
 | Media file 12: Axial T2-weighted magnetic resonance image of the hip in a patient with a mass in the anterior left upper thigh and/or inguinal region (same patient as in Image 11). The mass is inseparable from the underlying femoral cortex and contains strikingly hyperintense cystic areas with irregular septa of intermediate signal intensity. |
