 | Media file 1: A 67-year-old man presented with a slowly growing mass on the left side of his groin and with mild left leg claudication (same patient as in Images 2-5). The patient was a nonsmoker and was not diabetic. T1-weighted, coronal magnetic resonance imaging (MRI) shows a 5-cm, low–signal-intensity, lobulated mass in the left upper thigh. |
 | Media file 2: T2-weighted, coronal magnetic resonance imaging (MRI) scan of the left upper thigh in a 67-year-old man who presented with a slowly growing mass on the left side of his groin and with mild left leg claudication (same patient as in Images 1 and 3-5). The image shows a high–signal-intensity, lobulated, septate mass in the region of the groin. |
 | Media file 3: Contrast-enhanced, axial magnetic resonance imaging (MRI) scan of the upper thigh in a 67-year-old man who presented with a slowly growing mass on the left side of his groin and with mild left leg claudication (same patient as in Images 1-2 and 4-5). The image shows fairly intense tumor enhancement. |
 | Media file 4: Short-tau inversion recovery, turbo spin-echo, axial magnetic resonance imaging (MRI) scan of the left upper thigh in a 67-year-old man who presented with a slowly growing mass on the left side of his groin and with mild left leg claudication (same patient as in Images 1-3 and 5). The image shows fluid signal intensity within the tumor. |
 | Media file 5: Magnetic resonance (MR) angiogram of the leg vessels in a 67-year-old man who presented with a slowly growing mass on the left side of his groin and with mild left leg claudication (same patient as in Images 1-4). The image shows medial displacement and compression of the left femoral artery, superficial femoral artery, and profunda by the tumor, which resulted in the claudication. |
 | Media file 6: Moderately hypervascular tumor in the right upper thigh shows irregular, fine tumor vessels and areas of tumor stain (see also Image 7). |
 | Media file 7: Moderately hypervascular tumor in the right upper thigh shows irregular, fine tumor vessels and areas of tumor stain (see also Image 6). |
 | Media file 8: Sagittal, T1-weighted magnetic resonance imaging (MRI) scan in a 32-year-old woman presenting with a palpable mass above the left popliteal fossa. The image shows a low–signal-intensity, lobulated mass in the region of the Hunter canal (same patient as in Images 9-12). |
 | Media file 9: Axial, T1-weighted magnetic resonance imaging (MRI) scan in a 32-year-old woman obtained through a palpable mass above the left popliteal fossa. The image shows a low–signal-intensity, lobulated mass (same patient as in Images 8 and 10-12). |
 | Media file 10: Axial, T2-weighted magnetic resonance imaging (MRI) scan in a 32-year-old woman presenting with a palpable mass above the left popliteal fossa (same patient as in Images 8-9 and 11-12). The image shows a high–signal-intensity, lobulated mass. |
 | Media file 11: Fat-saturated magnetic resonance imaging (MRI) scan through the tumor in a 32-year-old woman presenting with a palpable mass above the left popliteal fossa (same patient as in Images 8-10 and 12). The image shows fluid signal intensity within the mass. |
 | Media file 12: Ultrasonogram in a 32-year-old woman with a mass above the left popliteal fossa (same patient as in Images 8-11) shows a hypoechoic (but solid) mass. |
 | Media file 13: A 50-year-old man presented with a 6-month history of a dull ache over the right hypochondrium (same patient as in Image 14). An ultrasonogram (not shown) depicted a poorly defined, infiltrating, echogenic mass in the right hepatic lobe with shadowing. A nonenhanced, axial computed tomography (CT) scan shows a low fat-attenuating mass under the diaphragm; the mass displaces the liver to the left. |
 | Media file 14: Hepatic angiogram in a 50-year-old man who presented with a 6-month history of a dull ache over the right hypochondrium (same patient as in Image 13). The image shows a hypovascular mass that displaces the liver medially. The mass was believed to represent a retroperitoneal liposarcoma; however, at laparotomy, the tumor was discovered to be intrahepatic. The histologic appearance was that of a high-grade liposarcoma infiltrating the diaphragm. |
 | Media file 15: A plain radiograph of a left femur demonstrates a large, soft-tissue mass projected over the medial aspect of the thigh (arrowheads). Small areas of radiolucency (asterisk) and calcification (arrow) are shown. |
 | Media file 16: Magnetic resonance imaging (MRI) scans (coronal, T1-weighted image and axial, T1-weighted image with fat saturation) show a soft-tissue mass of the posterior aspect of the thigh. It has a predominantly low T1 signal intensity except in its inferior portion, which has a high T1 signal intensity isointense to subcutaneous fat. Complete suppression is shown on the axial, T1-weighted image with fat saturation (asterisk). |
 | Media file 17: Computed tomography (CT) scan of the left thigh shows a huge mass (arrows) with predominant fat attenuation. The central soft-tissue component (asterisk) and thick, internal septations are consistent with liposarcoma. |
 | Media file 18: Contrast-enhanced, axial computed tomography (CT) scan of an abdomen demonstrates a huge, intra-abdominal, fatty mass with a soft-tissue component (arrow) and thick septations. The mass displaces the descending colon and the left kidney posteriorly. |
