FIG 2.

Ultrasonographic evaluation of biliary tree from a pyruvate kinase-deficient Somali cat: the enlarged gall bladder (A) contained biliary sludge and a hyperechoic focus with accompanying acoustic shadow representing a cholelith. A tortuous and dilated common bile duct, with a diameter of 6 to 7 mm diameter [normal range <5 mm (Leveillé and others 1996)], was also noted (B). Hepatic parenchyma appeared of normal echogenicity and intrahepatic bile ductules were not dilated. Three choleliths (C) of 8 to 12 mm composed exclusively of bilirubin (atomic absorption spectrophotometry) were found at necropsy
