82-year-old female with liver lesions likely consistent with cysts. Evaluate liver lesions seen on CT for evidence of malignancy. Also evaluate for signs of chronic liver disease. LIVER: Normal echogenicity of the liver. Multiple cysts are noted in the right hepatic lobe, the largest of which is located along the inferior aspect of the right hepatic lobe measuring 3.6 cm x 3.1 cm x 4.1 cm containing internal septations and some debris with suggestion of peripheral nodularity. Two additional smaller cysts are noted containing thin internal septations, one of which measures 2.5 cm x 1.8 cm x 2.1 cm, and the second cyst measures 1.7 cm x 1.8 cm x 1.4 cm. Main portal vein is patent with appropriate directional flow; peak velocity measures 17.1 cm/sec.GALLBLADDER, BILIARY TRACT: Status post cholecystectomy. Common duct measures up to 1.0 cm in caliber. No intra-or extrahepatic biliary ductal dilatation. PANCREAS: Tail of the pancreas is obscured by overlying bowel gas. The remaining visualized portions are increased in echogenicity suggestive of fatty atrophy.RIGHT KIDNEY: Normal echogenicity of the right kidney measuring 10.7 cm in length. No hydronephrosis or shadowing calculi are noted.OTHER: Normal echogenicity of the spleen measuring 9.8 cm in length.Normal echogenicity of the left kidney measuring 10.2 cm in length. No hydronephrosis or shadowing calculi are noted.
Dominant complex cyst at the inferior aspect of the right hepatic lobe with suggestion of peripheral nodularity. Recommend MRI for further evaluation. Additional smaller minimally complex cysts are likely benign.
