Multiple well-differentiated retroperitoneal liposarcomas with different patterns of appearance on computed tomography: A case report

Figure 2 Abdominal-pelvic computed tomography showing two masses. The left one exhibited a fat-like density with a -65 HU value, a clear boundary, and a convoluted vascular course, and contrast-enhanced scanning did not show significant enhancement; the right one had a mixed density, and contrast-enhanced scanning yielded the following computed tomography values during the three phases: 28/31/50 HU.
