2024年11月14日 · Intrahepatic biliary dilatation is a condition where the bile ducts within the liver become enlarged, often due to an obstruction or blockage. Medical imaging plays an important role in detecting and assessing intrahepatic biliary dilatation.

2022年6月1日 · If dilation of the common bile duct is detected incidentally with ultrasonography or computed tomography (CT) and the patient has clinical signs (eg, jaundice, pruritus, fever, weight loss), concerning laboratory test results (eg, elevated total bilirubin), or additional concerning imaging findings , then further evaluation is indicated with ...

2020年11月22日 · The bile ducts can get dilated for various reasons such as a blockage, infection, pancreatitis, functional problem, and medications. What are the symptoms of dilated bile ducts? It depends on the cause. Some patients can be asymptomatic when the bile duct dilation is from a benign cause.

2023年7月26日 · A, Axial T2-weighted SSFSE image (A) and 3D MRCP maximum-intensity-projection image (B) show diffuse intrahepatic biliary duct dilatation, which is most pronounced in segment VIII, with multiple string and frondlike filling defects representing mucin and papillary tumor (arrows), respectively.

Secondary (also known as “acquired”) intrahepatic and extrahepatic bile duct dilatation is caused by diseases or acquired factors. 5 It has three characteristics: (i) dilatation occurs after the primary disease or the predisposing factors; (ii) the bile duct above the lesion is wholly dilated (versus local dilatation in congenital cases ...

2009年4月24日 · When we see intrahepatic bile duct dilatation with strictures and only mild dilatation, the first diagnosis we think of is primary sclerosing cholangitis (PSC). We know however that there is a long differential diagnistic list which includes: Cholangiocarcinoma; Metastatic disease (especially breast cancer) Iatrogenic bile duct strictures

The dilatation of the intrahepatic bile ducts is identified with the sensitivity of 92%, and its cause – with the accuracy of 71% . The reasons for dilatation vary and are associated with patency impairment ( Tab. 5 ).

In this report, we present a case of intrahepatic bile duct dilatation caused by a small simple cyst and discuss the management of cystic lesions of the liver. A 75-year-old woman was referred to our hospital for the evaluation of a cystic tumor of the liver with bile duct dilatation, which had been incidentally detected on ultrasonography.

2019年1月22日 · Adenocarcinoma of the pancreatic head or a stone in the distal common bile duct (CBD) results in generalized intrahepatic and extrahepatic bile duct dilatation to the level of obstruction. Peripheral cholangiocarcinoma may cause segmental dilatation of …

Biliary dilatation, when identified, may be separated into obstructive or nonobstructive causes. Clinical presentation should guide decisions on which, if any, additional investigations are necessary. Choledocholithiasis is the most common cause of obstructive dilatation and frequently requires decompression.

2019年1月1日 · Dilation may be present in isolated intrahepatic ducts, diffusely in the intrahepatic ducts, in the extrahepatic duct, or combinations thereof. If dilation is secondary to obstruction in the distal duct, diffuse dilation of intrahepatic and extrahepatic bile ducts will usually be seen.

Preoperative laboratory data such as alkaline phosphatase and CA 19-9, and imaging findings such as significant wall thickening and regional lymph node enlargement on CT, abrupt cut-off and separation of bile duct on cholangiogram are useful differential diagnostic markers for …

2020年1月22日 · Imaging revealed a hepatic hilar mass with marked bilateral biliary ductal dilatation. A diagnosis of cholangiocarcinom...

2021年5月12日 · Biliary dilatation (BD), also known as bile duct cyst, is a rare primary biliary disease. It can be congenital, and can also occur in adulthood, mainly manifesting as intrahepatic and extrahepatic bile duct single or multiple local dilatations.

Coexisting CBD and intrahepatic bile duct dilation, age, and jaundice were found to be indicators of pathologic lesions. Dilation of both the CBD and pancreatic duct was suggestive of pancreatic disease, especially pancreatic malignancy in the setting of obstructive jaundice.

5 天之前 · Characteristic cholangiographic features of primary sclerosing cholangitis. (a) Band-like stricture: A short, annular stricture is seen in the intrahepatic bile duct (arrowhead). (b) Beaded appearance: Alternating strictures and slightly dilated segments are seen in the intrahepatic bile duct (arrowheads).

2023年7月19日 · biliary duct dilatation can be attributed to papillary stenosis or sphincter of Oddi dys-function. Subsequently, we discuss two conditions in which the duct is pathologically dilated but not obstructed: congenital cystic dilatation (i.e., choledochal cyst) and in-traductal papillary neoplasm of the bile duct. Finally, we provide guidance regarding

2021年5月12日 · Most common, choledochal cyst or fusiform dilatation of the common bile duct, accounting for 80%–90% of all bile duct cysts (Fig. 3.2). It is a benign dilatation that occurs in any part of the intrahepatic or extrahepatic bile duct except the gallbladder. Type I is further subclassified into three types: Type I congenital choledochal cysts.

In three patients presenting different types of liver lesions, including isolated cyst, focal nodular hyperplasia (FNH), and hemangioma, intrahepatic bile duct dilatation was observed on US and CT. Final diagnosis was obtained by surgery in two cases (cyst and FNH) and by 1-year follow-up in one patient presenting an isolated hemangioma.
