Hepatic leiomyosarcoma in a 62-year old man (a-f) and sarcomatous hepatocellular carcinoma in a 56-year old man (g-l). On the contrast-enhanced dynamic CT coronal and axial images, hepatic leiomyosarcoma (a-c) exhibits isoenhancement on the AP and persistent or progressive enhancement into the center on the later phase (d-f). The sarcomatous hepatocellular carcinoma presents obvious peripheral enhancement on the AP (g-i) and subsequent wash out (j-l)
