An abdominal radiograph displayed increased opacity at the right upper quadrant, raising concern of hepatomegaly (Fig. 1).
CT features of primary hepatic leiomyosarcoma. (a) Unenhanced axial CT scan of the liver revealed a large, partial demarcated and heterogeneous low attenuation mass arising from the inferior part of the right lobe of the liver without notable calcification seen. (b) Contrast-enhanced axial and (c) coronal CT scan in the venous phase showed the mass enhancing heterogeneously and intensely with areas of necrosis or hemorrhage and having mass effect to adjacent right kidney and bowel loops.

On unenhanced images (Fig. 2a), the tumor appeared with heterogeneous hypodensity without notable calcifications. The mass enhanced heterogeneously and intensely after contrast medium injection (Ultravist  ; Bayer Schering Pharma AG, Berlin, Germany; 300 mgI/mL, injection volume 30 mL at a rate of 1.5 mL/s) with areas of low attenuation, suggesting necrosis or hemorrhage (Fig. 2b and c).
