When the intrahepatic bile duct wall has protrusions, it is clearly seen as central dots or a linear streak. [10] Caroli disease is commonly diagnosed after this “central dot sign” is detected on a CT scan or ultrasound. [10] However, cholangiography is the best, and final, approach to show the enlarged bile ducts as a result of Caroli disease.
The bile duct [1] [4] (formerly known as the common bile duct [4]) is a part of the biliary tract. [4] It is formed by the union of the common hepatic duct and cystic duct. It ends by uniting with the pancreatic duct to form the hepatopancreatic ampulla. It possesses its sphincter to enable the regulation of bile flow.
The ductules join to form bile ducts that eventually form either the right main hepatic duct that drains the right lobe of the liver, or the left main hepatic duct draining the left lobe of the liver. The two ducts join to form the common hepatic duct, which in turn joins the cystic duct from the gall bladder, to give the common bile duct.
Primary sclerosing cholangitis (PSC) is a long-term progressive disease of the liver and gallbladder characterized by inflammation and scarring of the bile ducts, which normally allow bile to drain from the gallbladder. Affected individuals may have no symptoms or may experience signs and symptoms of liver disease, such as yellow discoloration ...
Through aggregating tubules of increasing diameter, the bile leaves the liver and reaches the upstream (proximal) component of the common bile duct. Apparently, the common bile duct beyond (distal to) the gallbladder tends to normally have a greater tone so that the bile backs up into the gallbladder. When bile enters the duodenum (the first ...
