Right hepatic lobe lesion. The study is severely created by respiratory motion artifact.ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology size and contour.In segment 5/8 there is a very subtle T2 weighted mildly hyperintense focus measuring 1.4 x 1.2 cm (series 4/18). There may be very subtle restricted diffusion (series 9/18). The postcontrast images are severely motion degraded but there is suggestion of arterial enhancement and delayed phase washout in this region (series 17/153 and series 17/249). There is no retention of hepatobiliary contrast agent on the 3 hour delayed hepatobiliary phase images (series 5 image 68).No biliary ductal dilatation.The main portal vein appears patent.Status post cholecystectomy.SPLEEN: The spleen is normal in size without a focal lesion.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Numerous bilateral renal cysts are present. Mild left-sided hydronephrosis.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Trace ascites is noted.BONES, SOFT TISSUES: The lower lumbar spine fusion hardware is incompletely imaged.OTHER: No significant abnormality noted.
Severely respiratory motion degraded study. A 1.4 cm right hepatic lobe segment 5/8 lesion likely corresponds to the incidental lesion seen on the recent ultrasound. Due to the poor image quality from respiratory motion it is difficult to confidently assess the characteristics of this lesion. Overall, the lesion does not have the appearance of a benign lesion such as a cyst or hemangioma. A small hepatocellular carcinoma cannot be excluded, especially if the patient has a history of chronic liver disease. A dedicated liver CT would be helpful in characterizing the lesion given the shorter scan time.
