HG Dilated bile ducts are usually caused by an obstruction of the biliary tree, which can be due to stones, tumors (usually of either the papilla of Vater or the pancreas), benign strictures (due to chronic pancreatitis or primary sclerosing cholangitis), benign stenosis of the papilla (ie, papillary stenosis), or a
Similarly, what is intrahepatic duct dilatation?
Biliary obstruction caused by small simple cysts is very rare. We present a case of biliary dilatation caused by a simple cyst with a 4-cm diameter. Biliary obstruction caused by a simple cyst is very rare,1–4 and dilatation of the intrahepatic bile duct in association with tumor lesions usually indicates malignancy.
Similarly, what is intrahepatic and extrahepatic bile duct dilatation? An intrahepatic bile duct diameter of 5 mm is called mild, 5-9 mm moderate, and >9 mm severe dilatation. Intrahepatic and extrahepatic bile duct dilatation is. common in clinical practice. In addition to congenital and. acquired factors like bile duct stones, parasites, and bile duct.
Similarly one may ask, what does no intrahepatic ductal dilatation mean?
The absence of bile duct dilatation does not exclude the presence of clinically significant biliary obstruction. For example, dilatation that may be seen in patients with Caroli disease, or choledochal cysts, can have the radiographic appearance of bile duct dilation without the presence of obstruction.
Is a dilated bile duct serious?
A biliary obstruction is a blockage of the bile ducts. The bile ducts carry bile from the liver and gallbladder through the pancreas to the duodenum, which is a part of the small intestine. However, if the blockage remains untreated for a long time, it can lead to life-threatening diseases of the liver.
