ABDOMEN:LIVER, BILIARY TRACT: Multiple bilobar metastatic disease is again noted in addition to a previously described right hepatic lobe hemangioma.Two reference metastatic lesions at the dome are unchanged compared to CT abdomen and pelvis 03/13/2015. The reference right hepatic dome lesion measures 1.8 x 2.5 cm (series 1002, image 96), previously 1.8 x 2.5 cm.
