The common bile duct is not visualized. At the porta, only two structures are identified, the portal vein and hepatic artery. There is increased echogenicity along anterior wall of portal vein consistent with positive triangular cord sign. The area of increased echogenicity measures 3.6 mm in maximum thickness on transverse scan. On oblique longitudinal view, the area of increased echogenicity is seen paralleling the anterior wall of right portal vein in the expected location of common hepatic duct. The gall bladder is hypoplastic with thick wall and multiseptated appearance. Gall bladder measures 17 mm long and 2.5 mm wide, considered diminutive. The pancreas and spleen are normal. Liver also appears normal in size and echotexture.
