History of hepatitis C with lesion in segment 5 on outside MRI. ABDOMEN:LIVER, BILIARY TRACT: The liver is normal in morphology, size, signal intensity and enhancement. The T2 weighted hyperintense segment 7 peripheral lesion measures 1.2 cm without evidence of arterial enhancement, restricted diffusion or intracellular fat. There may be a thin enhancing septa within the lesion. The subtraction images are not reliable given the degree of misregistration due to motion. Punctate probable cyst in the right hepatic dome (series 7/27).No biliary ductal dilatation or vascular abnormality.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.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.
The segment 7 1.2 cm lesion (likely corresponding to that reported on outside MR as segment 5 lesion) demonstrates no definite arterial enhancement or other suspicious imaging features. This may represent a septated cyst or fibrosed hemangioma (given the outside hospital ultrasound appearance of an echogenic lesion). Continued follow-up with ultrasound to document stability in 3-6 months is recommended.
