Portal biliopathy: a multitechnique imaging approach

Abstract: Portal biliopathy (PB) is a disorder characterized by biliary ductal and gallbladder wall abnormalities seen in patients with extrahepatic portal vein obstruction. These abnormalities consist mainly of bile duct compression and tethering, stenoses, fibrotic strictures and dilatation of both extrahepatic and intrahepatic bile ducts, as well as gallbladder varices. In this pictorial essay, we describe the imaging findings of PB, which allow differentiation of this entity from other diseases that may have similar… Show more

“…The possible causes of EHPO include neonatal umbilical vein catheterization, thrombotic diathesis, dehydration and shock, intra-abdominal inflammation, abdominal post-operative complication, and direct portal vein invasion by malignancies [1]. Only small percentage of patients have symptoms such as abdominal pain, fever, cholangitis, and obstructive jaundice [2].…”

“…Portal biliopathy refers to bile duct abnormalities and gallbladder varix caused by EHPO or portal hypertension [1,3,6]. The possible causes of EHPO include neonatal umbilical vein catheterization, thrombotic diathesis, dehydration and shock, intra-abdominal inflammation, abdominal post-operative complication, and direct portal vein invasion by malignancies [1].…”

“…Hypertrophy of both collateral plexuses produces a scalloped or smooth indentation in the ductal lumen of the bile duct, which can progress to more dramatic narrowing, stenosis and kinking. The development of gallbladder varices as a collateral pathway via the cystic vein is also a characteristic feature of portal biliopathy (3). Although the prevalence of this condition, and of EHPVO in particular, is still not understood in detail, elevated hepatobiliary enzymes and cholangiographic abnormalities are considered to be (white arrows, A).…”

“…This classification system can also be applied to MRCP images. 18 Recent reports of MRCP imaging in PCC show that either type I or type III are the most frequent, with the extrahepatic bile ducts being the most common location of narrowing. 15 It is important to note that MRCP can overestimate bile duct stenosis compared to conventional cholangiographic studies as was seen in a retrospective study of 10 patients of EHPVO with direct cholangiographic comparison in 3 patients.…”
