A 56-year-old man with abdominal discomfort. (A, B) Abdominal sonography revealed a hypoechoic mass with low vascularity. (C) Non-enhancement CT showed a heterogeneous hypodense mass with areas of cystic changes in the right lobe. (D- F) After the contrast injection, the mass was slightly enhanced, especially on the edge.

Ultrasonography (Figure 1A, B) revealed a hypoechoic mass with unmarked arrangement in the right posterior lobe. Non-enhancement CT (Figure 1C) showed a heterogeneous mass with areas of cystic changes in the right lobe. On contrast enhancement CT (Figure 1D-F), solid components showed slight enhancement, while the cystic components were never enhanced.

A 63-year-old man with abdominal pain. (A-C) MR images revealed a mass with low signal intensity on T1-weighted imaging and high signal intensity on T2-weighted imaging. (D-F) The periphery of the mass was slightly enhanced during the arterial, portal or delayed phase of contrast enhancement. (G) On CT, a heterogeneous hypodense mass was revealed. (H-L) After contrast material injection, the mass showed gradual, inhomogeneous enhancement, with decreased enhancement on delayed scans.

At subsequent CT (Figure 2G-L), a heterogeneous multi-nodular mass was confirmed, occupying the segment 6.
