Male 66 years old s/p OLT for HCC, 1.5 lesion with enhancement on CT but no washout, evaluate further with HCC. ABDOMEN:LIVER, BILIARY TRACT: Postsurgical changes of liver transplant.The previously described segment 6 lesion measures 1.3 x 1.3 cm (series 1203, image 2). It is hypointense on both T1 and T2-weighted images with avid arterial enhancement, mild venous enhancement and no washout. On the arterial phase there appears to be a right hepatic artery branch vessel leading into the lesion. Amorphus low T2 signal is also seen posterior to the lesion and on delayed postcontrast images only an amorphus hypointense artifact is seen in this same area. This artifact may be related to turbulent/pulsatile flow within the lesion.A tubular focus of hypointensity along the fissure is of uncertain significance. It may be related to artifact from surgery.No intra or extrahepatic biliary ductal dilatation.SPLEEN: No significant abnormality noted.PANCREAS: The pancreas enhances normally. There is no pancreatic ductal dilatation.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: No significant abnormality noted.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.The previously described segment 6 lesion is favored to represent a vascular anomaly, for example an aneurysm.2.No evidence of recurrent hepatocellular carcinoma.
