History of right hepatic lobe lesion incidentally seen on breast MRI which has gradually increased in size since 2009. ABDOMEN:LIVER, BILIARY TRACT: The liver demonstrates normal parenchymal signal intensity. Within segment 5, there is a lobulated sharply marginated structure (series 4, image 10) measuring 16 x 22 mm. The structure demonstrates high T2 signal, does not enhance, and is compatible with a benign cyst. This cyst has increased in size from 2009 when it measured up to approximately 13 mm in greatest dimension. There are a few scattered additional subcentimeter cysts. No suspicious focal hepatic lesions are identified.No biliary ductal dilatation. No cholelithiasis.SPLEEN: No significant abnormality noted.PANCREAS: The pancreas demonstrates normal signal intensity and enhancement without focal lesions. The pancreatic duct is not dilated.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: A few subcentimeter simple cysts are present within the left kidney. No suspicious renal lesions are identified.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.
