Abstract

We report the radiologic findings of a rare case of undifferentiated embryonal sarcoma of liver (UES) in a 64-year-old female. To our knowledge, this is the unique case of adult UES that provide verification of the high growth rate of the tumor.

Figure

  • Fig. 1 A 64-year female with undifferentiated embryonal sarcoma of the liver. A. 7 months ago, abdominal CT showed a 0.4 cm hypodense lesion (arrow) in the segment 5 of the liver. B. Transverse US images show the huge and predominantly solid mass in the liver with peripheral cystic components. C. Contrast enhanced CT shows the 11.0 cm-sized hypoattenuating mass in the right lobe of liver with multiple thick septa. D. Coronal T2-weighted MR images show the large heterogeneous mass in the right lobe of the liver. Upper portion of the tumor is hyperintense with septation and lower portion is hypointense. In the lowest part of the mass, rupture (arrowheads) with asscociated intraperitoneal fluid (asterisk) is shown. E, F. Unenhanced T1-weighted and gadolinium contrast enhanced T1-weighted MR images show progressive enhancement of the periphery and septa. G. PET-CT shows diffuse mild FDG uptake in the peripheral portion of the mass. H. Photomicrograph (original magnification, × 200; H&E stain) shows undifferentiated spindle-shaped and large stellate cells in abundant myxoid stroma.
