Normal Anatomy of Gall bladder:The above ultrasound images show the normal anatomy of the gall bladder taken from different angles of the transducer during sonography. The parts seen here are the fundus, body, neck and the cystic duct. Note the close relation of the cystic duct to the portal vein. The cystic duct is well seen and appears tortuous in these images. 1) Carcinoma of gall bladder:This a middle aged male patient who presented with constipation. Ultrasound images of the liver and gall bladder reveal an ominous mass infiltrating the gall bladder wall with invasion of the right lobe of liver. There is also a large calculus seen in the gall bladder. These ultrasound images are diagnostic of gall bladder carcinoma.

Detailed examination revealed it to be a duplicate gall bladder. These ultrasound images of duplication of the gall bladder reveal 2 gall bladders adjacent to each other with 2 separate cystic ducts. After meals, both the gall bladders showed normal emptying. This is very rare, as it shows that both sacs are fully functional and connected to the Common bile duct.

Sonography reveals a well distended gall bladder with a stone in the neck of the gall bladder/ or cystic duct (see top). Ultrasound images of the liver reveal intrahepatic biliary tree dilatation, with a common bile duct (CBD) of normal calibre. Sonographic images of the liver give a false impression of the calculus being in the hepatic duct, due to the close proximity of the stone in the gall bladder neck. These ultrasound images are diagnostic of Mirizzi syndrome. This syndrome is caused by impacted calculus in the Gall bladder neck or cystic duct causing extrinsic compression of the common hepatic duct. A common predisposing factor for this is the low insertion of the cystic duct into the common hepatic duct. This makes the cystic duct almost parallel to the common hepatic duct.
