Reason: further assessment of liver heterogeneity seen on CT imaging History: CT imaging findings LIVER: The liver measures 15.9 cm in length. The background liver parenchymal echotexture is normal. Corresponding to the area of hypoattenuation in hepatic segment 6 on the recent CT, there is a somewhat geographic area of increased echogenicity measuring 2.2 x 1.6 x 2.6 cm. No additional focal hepatic lesions are identified. The portal vein is patent demonstrating normal hepatopetal flow with a velocity of 21.9 m/s.BILIARY TRACT: There is no evidence of cholelithiasis or pericholecystic fluid. Mild focal gallbladder wall thickening may reflect adenomyomatosis. The sonographic Murphy's sign is negative. No intrahepatic or extrahepatic biliary ductal dilatation is present. The common bile duct measures 6 mm in diameter.PANCREAS: No significant abnormalities noted.SPLEEN: No significant abnormalities noted.The spleen measures 10.8 cm in length. RIGHT KIDNEY: Kidney measures 11.4 cm in length. Normal echotexture. No hydronephrosis, shadowing calculus or mass.LEFT KIDNEY: Kidney measures 11.3 cm in length. Normal echotexture. No hydronephrosis, shadowing calculus or mass.OTHER: No significant abnormalities noted.
Nonspecific hyperechoic area within hepatic segment 6 corresponding to area of hypoattenuation on recent CT. Top differential considerations include focal fat deposition or hemangioma in the absence of known underlying malignancy. If further characterization is desired, MRI could be considered as clinically warranted.
