Abstract
Pathologic conditions of the biliary system, although common, can be difficult to diagnose clinically. Challenges in biliary imaging include anatomic variants and the dynamic nature of the biliary tract, which can change with age and intervention, blurring the boundaries of normal and abnormal. Choledochal cysts can have numerous appearances and are important to diagnose given the risk of cholangiocarcinoma potentially requiring surgical resection. Choledocholithiasis, the most common cause of biliary dilatation, can be difficult to detect at US and CT, with MRI having the highest sensitivity. However, knowledge of the imaging pitfalls of MRI and MR cholangiopancreatography is crucial to avoid misinterpretation. Newer concepts in biliary tract malignancy include intraductal papillary biliary neoplasms that may develop into cholangiocarcinoma. New paradigms in the classification of cholangiocarcinoma correspond to the wide range of imaging appearances of the disease and have implications for prognosis. Accurately staging cholangiocarcinoma is imperative, given expanding curative options including transplant and more aggressive surgical options. Infections of the biliary tree include acute cholangitis or recurrent pyogenic cholangitis, characterized by obstruction, strictures, and central biliary dilatation. Inflammatory conditions include primary sclerosing cholangitis, which features strictures and fibrosis but can be difficult to differentiate from secondary causes of sclerosing cholangitis, including more recently described entities such as immunoglobulin G4-related sclerosing cholangitis and COVID-19 secondary sclerosing cholangitis. The authors describe a wide variety of benign and malignant biliary tract abnormalities, highlight differentiating features of the cholangitides, provide an approach to interpretation based on the pattern of imaging findings, and discuss pearls and pitfalls of imaging to facilitate accurate diagnosis. ©RSNA, 2024 Supplemental material is available for this article.

Abstract
A 75-year-old man was referred to our department because of an enlarging intrahepatic mass detected on magnetic resonance imaging (MRI) follow-up for another disease. MRI showed hypointensity on T1-weighted imaging and hyperintensity on T2-weighted imaging in liver segment 4. Abdominal plain computed tomography (CT) indicated a low-density lesion with an unclear boundary, measuring approximately 4 cm × 3 cm in liver segment 4. Dynamic CT showed early rim enhancement and gradual central enhancement. Contrast-enhanced CT also showed occlusion of the portal vein in segment 4. As the possibility of intrahepatic cholangiocarcinoma could not be excluded on imaging studies, we performed laparoscopic left medial sectionectomy. Histologically, the lesion showed diminished numbers of hepatocytes with increased collagen fibers compared with normal, with no patent portal vein. We considered this lesion a reactive lesion caused by collapse of the liver parenchyma owing to localized obstruction and loss of the portal vein. This lesion was pathologically diagnosed as portal biliopathy. We experienced an extremely rare case of intrahepatic mass-forming portal biliopathy that mimicked a hepatic tumor, which was diagnosed by laparoscopic resection. Portal biliopathy rarely forms intrahepatic mass lesions and must be distinguished from a malignant hepatic tumor.

Abstract
Vascular compression syndromes are a diverse group of pathologies that can manifest asymptomatically and incidentally in otherwise healthy individuals or symptomatically with a spectrum of presentations. Due to their relative rarity, these syndromes are often poorly understood and overlooked. Early identification of these syndromes can have a significant impact on subsequent clinical management. This pictorial review provides a concise summary of seven vascular compression syndromes within the abdomen and pelvis including median arcuate ligament (MAL) syndrome, superior mesenteric artery (SMA) syndrome, nutcracker syndrome (NCS), May-Thurner syndrome (MTS), ureteropelvic junction obstruction (UPJO), vascular compression of the ureter, and portal biliopathy. The demographics, pathophysiology, predisposing factors, and expected treatment for each compression syndrome are reviewed. Salient imaging features of each entity are illustrated through imaging examples using multiple modalities including ultrasound, fluoroscopy, CT, and MRI.

[PMID: 38017393 PMCID: PMC10683077 DOI: 10.1186/s12876-023-03042-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 11/08/2023] [Indexed: 11/30/2023] Open
Abstract
BACKGROUND AND AIMS There are different therapeutic approaches for biliary strictures and reducing portal hypertension in patients with symptomatic portal cavernoma cholangiopathy (PCC). Endoscopic treatment includes endoscopic biliary sphincterotomy (EST), dilation of stricture with a biliary balloon, placement of plastic stent(s) and stone extraction. Fully covered self-expandable metal stent (FCSEMS) is placed as a rescuer in case of haemobilia seen after EST, dilation of stricture and removal of plastic stent rather than the stricture treatment itself. In this retrospective observational study, we sought to assess the clinical outcomes of FCSEMS as the initial treatment for PCC-related biliary strictures. MATERIALS AND METHODS Twelve symptomatic patients with PCC both clinically and radiologically between July 2009 and February 2019 were examined. Magnetic resonance cholangiopancreatography (MRCP) and cholangiography were employed as the diagnostic imaging methods. Chandra-Sarin classification was used to distinguish between biliary abnormalities in terms of localization. Llop classification was used to group biliary abnormalities associated with PCC. Endoscopic partial sphincterotomy was performed in all the patients. If patients with dominant strictures 6-8-mm balloon dilation was first performed. This was followed by removal of the stones if exist. Finally, FCSEMS placed. The stents were removed 6-12 weeks later. RESULTS The mean age of the patients was 40.9 ± 10.3 years, and 91.6% of the patients were male. Majority of the patients (n = 9) were noncirrhotic. Endoscopic retrograde cholangiopancreatography (ERCP) findings showed that 11 of the 12 patients were Chandra Type I and one was Chandra Type IIIa. All the 12 patients were Llop Grade 3. All patients had biliary involvement in the form of strictures. Stent placement was successful in all patients. FCSEMSs were retained for a median period of 45 days (30-60). Seven (58.3%) patients developed acute cholecystitis. There was no occurrence of bleeding or other complications associated with FCSEMS replacement or removal. All patients were asymptomatic during median 3 years (1-10) follow up period. CONCLUSIONS FCSEMS placement is an effective method in biliary strictures in case of PCC. Acute cholecystitis is encountered frequently after FCSEMS, but majority of patients respond to the medical treatment. Patients should be followed in terms of the relapse of biliary strictures.

Abstract
BACKGROUND AND AIM Shunt surgery is the definitive treatment for symptomatic patients with portal cavernoma cholangiopathy (PCC), but few patients are non-surgical candidates or fail to improve even after surgery. This study aims to analyze the long-term outcomes of endoscopic therapy in these patients. METHODS Retrospective review of a prospectively maintained database of all patients with symptomatic PCC managed with endoscopic retrograde cholangiography (ERC) followed by stent placement. Outcomes studied included number of biliary interventions, complications, resolution of stricture, development of decompensation and mortality. RESULTS Thirty-five patients (68.6% males, median age = 35 years) with a median follow-up duration of 46 months (12-112) were included in the analysis. Presentation was only jaundice in 51.4% cases while one-third (37.1%) of the patients presented with cholangitis. Patients underwent a total of 363 endoscopic sessions with a median of 9 procedures (3-29) per patient. Hemobilia was the most common complication of the procedure (6.06%). Ten (28.5%) patients required frequent stent exchanges. Patients who required frequent stent exchanges had higher number of cholangitis episodes and hospitalization. Secondary biliary cirrhosis developed in 4 (11.4%) patients and 2 (5.7%) patients had mortality. Of the 5 (14.3%) patients who were given a stent free trial, 3 patients required restenting due to redevelopment of symptoms. CONCLUSION Patients with PCC without shuntable veins for surgery or those who failed to improve after surgery can be managed long-term with repeated endoscopic intervention with a slightly increased risk of non-fatal hemobilia.

Abstract
PURPOSE To evaluate role of 3-T magnetic resonance portovenography (MRPV) in children with extra hepatic portal venous obstruction (EHPVO) and compare unenhanced and contrast-enhanced sequences. METHODS 20 Children with EHPVO underwent MRPV using unenhanced [T2, T1 pre-contrast, Balanced turbo field echo (BTFE)] and contrast-enhanced (CE) modified DIXON (mDIXON) sequences. The images were evaluated for the patency of abdominal veins, hepatic and splenic parenchyma by two radiologists for interobserver agreement. RESULTS BTFE and post-contrast mDIXON sequences performed best for evaluation of abdominal veins. Concordance between the BTFE and CE sequences was good to very good for both the radiologists for splenic vein (SV) evaluation. The concordance between the two sequences for evaluation of superior mesenteric vein and its confluence with the SV was less remarkable and varied from fair to good, while the interobserver agreement was very good to perfect. The interobserver agreement between the BTFE and CE sequence for the evaluation of left renal vein was very good, while that for IVC was perfect. The agreement between BTFE and CE sequence was perfect for the evaluation of right and middle hepatic veins, while the interobserver agreement was good to perfect. The interobserver agreement was poor for evaluation of hepatic parenchyma on BTFE sequence as compared to CE sequence, and moderate for splenic parenchyma. CONCLUSION BTFE sequence is the single best unenhanced MR pulse sequence to detect all the vascular structures in children with EHPVO. CE-MRI is not superior to BTFE sequence and should be used at the discretion of the radiologist.

Abstract
Vascular structures in the abdomen can compress or be compressed by adjacent structures. Classic imaging findings of vascular compressions, including median arcuate ligament syndrome, superior mesenteric artery syndrome, nutcracker syndrome, portal biliopathy, May-Thurner syndrome, and ureteropelvic junction obstruction will be discussed here. It is important to correlate imaging findings and clinical data to identify asymptomatic vascular compression which requires no treatment, intermittent vascular compression with nonspecific or vague clinical manifestation, and the subset of patients with true syndromes who will benefit from treatment.

Abstract
The idiopathic chronic cholangitides comprise a group of hepatobiliary diseases of probable autoimmune origin that are usually asymptomatic in the initial stages and can lead to cirrhosis of the liver. Elevated cholestatic enzymes on blood tests raise suspicion of these entities. Among the idiopathic cholangitides, the most common is primary sclerosing cholangitis, which is associated with inflammatory bowel disease and with an increased incidence of hepatobiliary and digestive tract tumors. It is important to establish the differential diagnosis with IgG4-associated cholangitis, primary biliary cholangitis, and secondary cholangitides, because the therapeutic management is different. Magnetic resonance cholangiopancreatography (MRCP) is the best test to evaluate the intrahepatic and extrahepatic biliary tract, and MRI also provides information about the liver and other abdominal organs. An appropriate MRCP protocol and knowledge of the different findings that are characteristic of each entity are essential to reach the correct diagnosis.

Abstract
Portal cavernoma cholangiopathy (PCC) is one of the most harrowing complications of extrahepatic portal venous obstruction, as it determines the long-term hepatobiliary outcome. Although symptomatic PCC is rare in children, asymptomatic PCC is as common as that in adults. However, there are major gaps in the literature with regard to the best imaging strategy and management modality in children. Moreover, natural history of PCC and effect of portosystemic shunt surgeries in children are unclear. Neglected PCC would lead to difficult or recalcitrant biliary strictures that will require endoscopic therapy or bilioenteric anastomosis, both of which are challenging in the presence of extensive collaterals. There are limited studies on the effect of portosystemic shunt surgeries on the outcome of PCC in children compared to adults. In this review, we aimed to collate all existing literature on PCC in childhood and also compare with adult studies. We highlight the difficulties of this disease to provide a comprehensive platform to foster further research on PCC exclusively in children.

CT imaging findings of abdominopelvic vascular compression syndromes: what the radiologist needs to know. Insights Imaging 2020; 11:48.

Abstract
Abdominopelvic vascular compression syndromes include a variety of uncommon conditions characterized by either extrinsic compression of blood vessels by adjacent anatomical structures (i.e., median arcuate ligament syndrome, nutcracker syndrome, May-Thurner syndrome) or compression of hollow viscera by adjacent vessels (i.e., superior mesenteric artery syndrome, ureteropelvic junction obstruction, ureteral vascular compression syndromes, portal biliopathy). These syndromes can be unexpectedly diagnosed even in asymptomatic patients and the predisposing anatomic conditions can be incidentally discovered on imaging examinations performed for other indications, or they can manifest with atypical abdominal symptoms and acute complications, which may lead to significant morbidity if unrecognized. Although computed tomography (CT) is an accurate noninvasive technique for their detection, the diagnosis remains challenging due to the uncommon clinical presentation and often overlooked imaging features. Dynamic imaging may be performed in order to evaluate patients with inconstant symptoms manifesting in a specific position. The purposes of this paper are to review the CT imaging findings of abdominopelvic vascular compression syndromes, correlating with anatomical variants and to provide key features for the noninvasive imaging diagnosis.

Abstract
Portal hypertensive biliopathy is characterized by abnormalities in the biliary tract secondary to portal hypertension, especially extrahepatic portal vein obstruction. Most patients are asymptomatic; only about 20% have clinical symptoms. We herein report a case of portal hypertensive biliopathy caused by cavernous transformation of the portal vein with the development of recurrent cholangitis with common bile duct stones and stricture. This patient underwent endoscopic retrograde cholangiopancreatography, a surgical operation, and a transvenous intrahepatic portosystemic shunt procedure during the whole clinical process. Finally, we found the recurrent plastic stent insertion at endoscopic retrograde cholangiopancreatography was the best option for him at present. In addition, we also discussed the diagnosis and management of this disease.

Abstract
Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are prototype noncirrhotic causes of portal hypertension (PHT), characterized by normal hepatic venous pressure gradient, variceal bleeds, and moderate to massive splenomegaly with preserved liver synthetic functions. Infections, toxins, and immunologic, prothrombotic and genetic disorders are possible causes in IPH, whereas prothrombotic and local factors around the portal vein lead to EHPVO. Growth failure, portal biliopathy, and minimal hepatic encephalopathy are long-term concerns in EHPVO. Surgical shunts and transjugular intrahepatic portosystemic shunt resolve the complications secondary to PHT. Meso-Rex shunt is now the standard-of-care surgery in children with EHPVO.

Abstract
INTRODUCTION The hepatoduodenal ligament is frequently involved by conditions affecting the portal triad and surrounding structures, including a vast array of non-neoplastic conditions. Due its unique location between the retroperitoneum and the peritoneal space, the hepatoduodenal ligament is also targeted by inflammatory conditions involving the retroperitoneum and the liver. Finally, the presence of lymphatics and of the biliary tracts makes the hepatoduodenal ligament a route of spread for a variety of infections. The purpose of this pictorial essay is twofold: to review the cross-sectional radiological anatomy and variants of the structures within the hepatoduodenal ligament, and to illustrate the non-neoplastic conditions that may arise within the hepatoduodenal ligament. CONCLUSION Familiarity with these specific entities and their cross-sectional imaging findings is fundamental for a more accurate diagnosis.

Abstract
Objectives Portal cavernoma cholangiopathy (formerly portal biliopathy) is a type of biliary injury that occurs in association with a portal vein thrombus or cavernoma. Although the radiographic features of portal cavernoma cholangiopathy have been enumerated in the literature, its histologic features have not been described in detail. Methods We describe the histologic findings in liver specimens from three patients with radiologically confirmed portal cavernoma cholangiopathy. Results Of the three patients, one underwent surgical resection due to a clinical suspicion for cholangiocarcinoma, one had a liver biopsy sample obtained for evaluation of possible cirrhosis, and one had a clinically suspicious "hilar mass" at the time of orthotopic liver transplant. Histologic features common among the three liver specimens included portal venous abnormalities, where the portal veins were obliterated or small relative to the portal tract size, and obstructive biliary changes, such as ductular reaction and reactive epithelial atypia accompanied by a mixed inflammatory cell infiltrate with neutrophils. Conclusions This case series provides clinicopathologic characteristics of portal cavernoma cholangiopathy. Histologic changes are reminiscent of hepatoportal sclerosis and/or bile duct obstruction. Attention to portal veins can provide helpful diagnostic clues, especially when biopsy samples are obtained from patients with a known portal vein thrombus or cavernoma.

Abstract
Non-cirrhotic portal hypertension (NCPH) comprises a group of diseases that are characterized by increased portal pressure in the absence of cirrhosis of the liver. It may arise as a result of either primary hepatic disease or the effects of systemic disorders on liver. The natural course of NCPH is largely indolent and benign with an overall better outcome than cirrhosis, as long as the complications of portal hypertension are properly managed and regular surveillance is carried out. However, due to the numerous and variable etiological factors and lack of standardized diagnostic criteria, this entity is under-recognized clinically as well as pathologically and often gets mislabeled as cryptogenic cirrhosis. Therefore, it is imperative for radiologists to be aware of the imaging features of various entities that constitute NCPH to facilitate early recognition of this disorder. The present review shall comprehensively discuss the role of imaging in the diagnosis of obliterative portal venopathy, which is a common and one of the most poorly understood disorders leading to NCPH. The other radiologically relevant entities will also be briefly appraised.

Abstract
BACKGROUND Idiopathic portal hypertension (IPH) and extrahepatic portal venous obstruction (EHPVO) are non-cirrhotic vascular causes of portal hypertension (PHT). Variceal bleed and splenomegaly are the commonest presentations. AIM The present review is intended to provide the existing literature on etiopathogenesis, clinical profile, diagnosis, natural history and management of IPH and EHPVO. RESULTS IPH and EHPVO are both characterized by normal hepatic venous pressure gradient, moderate to massive splenomegaly with preserved liver synthetic functions. While the level of block in IPH is presinusoidal, in EHPVO it is at prehepatic level. Infections, autoimmunity, drugs, immunodeficiency and prothrombotic states are possible etiological agents in IPH. Contrastingly in EHPVO, prothrombotic disorders and local factors around the portal vein are the incriminating factors. Diagnosis is often clinical, supported by simple radiological tools. Natural history is defined by episodes of variceal bleed and symptoms related to enlarged spleen. Growth failure, portal biliopathy and minimal hepatic encephalopathy are additional concerns in EHPVO. Long-term survival is reasonably good with endoscopic surveillance; however, parenchymal extinction leading to decompensation is seen in a minority of patients in both the disorders. Surgical shunts revert the complications secondary to PHT. Meso-Rex shunt has become the standard surgery in children with EHPVO. CONCLUSION This review gives a detailed summary of these two vascular conditions of liver-IPH and EHPVO. Further research is needed to understand the pathogenesis and natural history of these disorders.

Abstract
Portal hypertensive biliopathy (PHB) is described as abnormalities of the walls of the biliary tree secondary to portal hypertension. Gastrointestinal bleeding caused by PHB is rare. PHB as a cause of serious bleeding after sphincteroplasty during ERCP is extremely rare. Here, we report a case of PHB in a young Saudi male with cell sickle anemia who developed massive hemorrhage during ERCP after balloon dilation of the ampulla of Vater. We further discussed the diagnosis and management. To the best of our knowledge, no such case has been reported.

Abstract
The term portal cavernoma cholangiopathy refers to the biliary tract abnormalities that accompany extrahepatic portal vein obstruction (EHPVO) and subsequent cavernous transformation of the portal vein. EHPVO is a primary vascular disorder of the portal vein in children and adults manifested by longstanding thrombosis of the main portal vein. Nearly all patients with EHPVO have manifestations of portal cavernoma cholangiopathy, such as extrinsic indentation on the bile duct and mild bile duct narrowing, but the majority are asymptomatic. However, progressive portal cavernoma cholangiopathy may lead to severe complications, including secondary biliary cirrhosis. A spectrum of changes is seen radiologically in the setting of portal cavernoma cholangiopathy, including extrinsic indentation of the bile ducts, bile duct stricturing, bile duct wall thickening, angulation and displacement of the extrahepatic bile duct, cholelithiasis, choledocholithiasis, and hepatolithiasis. Radiologists must be aware of this disorder in order to provide appropriate imaging evaluation and interpretation, to facilitate appropriate treatment and to distinguish this entity from its potential radiologic mimics.

Abstract
Portal biliopathy (PB) is defined as the presence of biliary abnormalities in patients with non-cirrhotic/non-neoplastic extrahepatic portal vein obstruction (EHPVO) and portal cavernoma (PC). The pathogenesis of PB is due to ab extrinseco compression of bile ducts by PC and/or to ischemic damage secondary to an altered biliary vascularization in EHPVO and PC. Although asymptomatic biliary abnormalities can be frequently seen by magnetic resonance cholangiopancreatography in patients with PC (77%-100%), only a part of these (5%-38%) are symptomatic. Clinical presentation includes jaundice, cholangitis, cholecystitis, abdominal pain, and cholelithiasis. In this subset of patients is required a specific treatment. Different therapeutic approaches aimed to diminish portal hypertension and treat biliary strictures are available. In order to decompress PC, surgical porto-systemic shunt or transjugular intrahepatic porto-systemic shunt can be performed, and treatment on the biliary stenosis includes endoscopic (Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy, balloon dilation, stone extraction, stent placement) and surgical (bilioenteric anastomosis, cholecystectomy) approaches. Definitive treatment of PB often requires multiple and combined interventions both on vascular and biliary system. Liver transplantation can be considered in patients with secondary biliary cirrhosis, recurrent cholangitis or unsuccessful control of portal hypertension.

Abstract
Portal biliopathy refers to cholangiographic abnormalities which occur in patients with portal cavernoma. These changes occur as a result of pressure on bile ducts from bridging tortuous paracholedochal, epicholedochal and cholecystic veins. Bile duct ischemia may occur due prolonged venous pressure effect or result from insufficient blood supply. In addition, encasement of ducts may occur due fibrotic cavernoma. Majority of patients are asymptomatic. Portal biliopathy is a progressive disease and patients who have long standing disease and more severe bile duct abnormalities present with recurrent episodes of biliary pain, cholangitis and cholestasis. Serum chemistry, ultrasound with color Doppler imaging, magnetic resonance imaging with magnetic resonance cholangiopancreatography and magnetic resonance portovenography are modalities of choice for evaluation of portal biliopathy. Endoscopic retrograde cholangiography being an invasive procedure is indicated for endotherapy only. Management of portal biliopathy is done in a stepwise manner. First, endotherapy is done for dilation of biliary strictures, placement of biliary stents to facilitate drainage and removal of bile duct calculi. Next portal venous pressure is reduced by formation of surgical porto-systemic shunt or transjugular intrahepatic portosystemic shunt. This causes significant resolution of biliary changes. Patients who persist with biliary symptoms and bile duct changes may benefit from surgical biliary drainage procedures (hepaticojejunostomy or choledechoduodenostomy).

Abstract
Extrahepatic portal vein obstruction (EHPVO) is a primary vascular condition characterized by chronic long standing blockage and cavernous transformation of portal vein with or without additional involvement of intrahepatic branches, splenic or superior mesenteric vein. Patients generally present in childhood with multiple episodes of variceal bleed and EHPVO is the predominant cause of paediatric portal hypertension (PHT) in developing countries. It is a pre-hepatic type of PHT in which liver functions and morphology are preserved till late. Characteristic imaging findings include multiple parabiliary venous collaterals which form to bypass the obstructed portal vein with resultant changes in biliary tree termed portal biliopathy or portal cavernoma cholangiopathy. Ultrasound with Doppler, computed tomography, magnetic resonance cholangiography and magnetic resonance portovenography are non-invasive techniques which can provide a comprehensive analysis of degree and extent of EHPVO, collaterals and bile duct abnormalities. These can also be used to assess in surgical planning as well screening for shunt patency in post-operative patients. The multitude of changes and complications seen in EHPVO can be addressed by various radiological interventional procedures. The myriad of symptoms arising secondary to vascular, biliary, visceral and neurocognitive changes in EHPVO can be managed by various radiological interventions like transjugular intra-hepatic portosystemic shunt, percutaneous transhepatic biliary drainage, partial splenic embolization, balloon occluded retrograde obliteration of portosystemic shunt (PSS) and revision of PSS.

Abstract
BACKGROUND Magnetic resonance cholangiopancreatography/magnetic resonance splenoportovenography (MRCP/MRSPV) is now the investigation of choice for the diagnosis of portal cavernoma cholangiopathy (PCC). Endoscopic ultrasound (EUS) is an emerging diagnostic modality for the diagnosis of PCC and may be better than MRCP/MRSPV to see the layer-wise localization of varices and to differentiate between varices, stone, and malignancy. METHODS Retrospective data of 50 patients of extrahepatic portal vein obstruction (EHPVO) were collected, and comparison between MRCP/MRSPV and EUS was done for the diagnosis of PCC. RESULTS Out of 50 patients, 56 % (28) were males, 44 % (22) females, and 24 % (12) symptomatic. Biliary changes were seen in 40 patients (80 %). Epicholedochal collateral (EPEC) was detected in 48 % and 20 % in MRCP/MRSPV and EUS, respectively. Perforators (PER) and intracholedochal collateral (ICC) were better seen with EUS (72 % and 48 %) as compared to MRCP/MRSPV (0 % and 8 %), and p-values were significant (<0.05). EUS has a sensitivity of 33.33 % and a specificity of 92.31 % for EPEC. Portal cavernoma (PC) and collateral at porta (CP), paracholedochal collateral (PAC), perisplenic (PS) and peripancreatic collateral (PPC), pericholedochal collateral (PEC), intrahepatic biliary radical dilatation (IHBRD), perigallbladder collateral (PG), common bile duct dilatation (CBDD) and common hepatic duct dilatation (CHDD), common bile duct stricture (CBDS), and retropancreatic collateral (RPC) were comparable between the two modalities. CONCLUSIONS EUS detected PER and ICC better than MRCP/MRSPV, while MRCP/MRSPV was more sensitive for detecting EPEC.

Abstract
Portal vein thrombosis (PVT) is a frequent complication of liver cirrhosis, but it can also occur as a primary vascular disorder amid absent liver disease. Extrahepatic portal vein obstruction (EHPVO) refers to the obstruction of the extrahepatic portal vein with or without involvement of the intrahepatic portal vein branches, splenic and/or superior mesenteric vein. It is a distinct disorder that excludes PVT occurring in concurrence with liver cirrhosis or hepatocellular carcinoma. The term "EHPVO" implies chronicity and is principally reserved for a long-standing condition characterized by cavernous transformation of the portal vein. The most characteristic imaging manifestation is the formation of portoportal collaterals (via the venous plexi of Petren and Saint) that allow hepatopetal flow. However, this collateral circulation is insufficient resulting in clinically significant pre-hepatic portal hypertension, wherein the liver function and structure remain preserved until late. Although the long-term (more than 10 years) survival with controlled variceal bleeding is up to 100%, affected individuals have an impaired quality of life owing to portal cavernoma cholangiopathy, hypersplenism, neurocognitive dysfunction and growth retardation. Imaging diagnosis is not always straightforward as the collaterals can also present as a tumour-like solid mass that can be inadvertently biopsied. Moreover, EHPVO has its implications for the biliary tree, arterial circulation, liver/splenic volumes and stiffness, which merit proper understanding but have not been so well described in literature. In this review, we present the complete spectrum of the vascular, biliary and visceral changes with a particular emphasis on what our medical/surgical hepatology colleagues need to know from us in the pre-operative and post-operative settings.

Abstract
Introduction Biliary obstruction is usually caused by choledocholithiasis. However, in some circumstances, alternative or concurring unusual ethiologies such as portal hypertensive biliopathy (PHB) must be considered. Clinical case We present the case of a 36-year-old female complaining of jaundice and pruritus. Liver function tests were compatible with biliary obstruction and the ultrasound scan of the abdomen showed dilatation of the intrahepatic biliary ducts, a dilated common bile duct (CBD) and biliary calculi. The computed tomography of the abdomen revealed a portal cavernoma encasing the CBD. Discussion Portal cavernoma, the hallmark of extrahepatic portal venous obstruction, can cause PHB. When symptomatic, chronic cholestasis is present if a dominant stricture exists whereas biliary pain and acute cholangitis occur when choledocholithiasis prevails. Management must be individualized and usually includes endoscopic therapy to address choledocholithiasis and shunt surgery for definitive treatment.

Abstract
Portal biliopathy (PB) is a rare disorder, characterized by biliary ductal and gallbladder wall abnormalities seen in patients with portal hypertension. It most commonly occurs due to idiopathic extrahepatic portal vein obstruction (EHPVO). The abnormalities consist mainly of bile duct compression, stenoses, fibrotic strictures and dilation of both extrahepatic and intrahepatic bile ducts, as well as gallbladder varices. PB may mimic cholangiocarcinoma, sclerosing cholangitis, or choledocholithiasis. Misdiagnosis can be avoided using appropriate imaging modalities to prevent complications. We present the magnetic resonance imaging (MRI) and magnetic resonance cholangiography (MRCP) features of three patients with PB.

Abstract
PURPOSE The radiologist can encounter benign significant imaging findings on computed tomography that can be incorrectly interpreted as neoplasm. The authors review several benign findings and demonstrate several methods to differentiate these findings from more sinister pathology. CONCLUSION It is imperative for the radiologist to be cognizant of and how to correctly identify mimickers of pathology so that unnecessary interventions and surgeries are avoided.

Abstract
Portal cavernoma cholangiopathy (PCC) refers to the biliary changes which occur in the setting of extrahepatic portal vein obstruction and secondary portal cavernoma formation. The main radiological findings include the vascular changes in the form of portosystemic collaterals and biliary changes in the form of extrinsic impressions and strictures. Till date, conventional cholangiography has been the gold standard for the diagnosis of PCC. However, it is an invasive procedure and is associated with complications. At present there is a transition towards non-invasive modalities like ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI). The recent advances in these modalities provide an excellent delineation of both the vascular and the biliary changes non-invasively in a short time. The findings of PCC using these newer modalities are not so well described in literature. The findings of PCC also overlap with malignant conditions of biliary tract such as cholangiocarcinoma and compression of biliary tract by malignant adenopathies. In this article we describe the vascular and biliary changes associated with PCC on US, CT and MRI. We also describe the imaging findings using each modality along with their advantages and disadvantages.

Abstract
Portal cavernoma cholangiopathy (PCC) refers to a constellation of secondary changes in the biliary tree in patients with chronic portal vein (PV) thrombosis and portal cavernoma formation. These findings of PCC are seen in the extra-hepatic bile duct(s), with or without involvement of the 1st or 2nd degree intra-hepatic bile ducts. Of all patients with chronic PV thrombosis, cholangiographic features of PCC are found in 80%-100%. The biliary changes are symptomatic in a smaller proportion of 5%-38% patients. Choledocholithiasis and hepatolithiasis occur in 5%-20%, independent of the occurrence of cholelithiasis. We review the published literature on cholangiographic description of PCC. We also propose standardized nomenclature for the cholangiographic findings, namely: extrinsic impressions/indentations, shallow impressions, irregular ductal contour, stricture (s), upstream dilatation, filling defects, bile duct angulation, and ectasia.

Abstract
Portal cavernoma develops as a bunch of hepatopetal collaterals in response to portomesenteric venous obstruction and induces morphological changes in the biliary ducts, referred to as portal cavernoma cholangiopathy. This article briefly reviews the available literature on the vascular supply of the biliary tract in the light of biliary changes induced by portal cavernoma. Literature pertaining to venous drainage of the biliary tract is scanty whereas more attention was focused on the arterial supply probably because of its significant surgical implications in liver transplantation and development of ischemic changes and strictures in the bile duct due to vasculobiliary injuries. Since the general pattern of arterial supply and venous drainage of the bile ducts is quite similar, the arterial supply of the biliary tract is also reviewed. Fine branches from the posterior superior pancreaticoduodenal, retroportal, gastroduodenal, hepatic and cystic arteries form two plexuses to supply the bile ducts. The paracholedochal plexus, as right and left marginal arteries, run along the margins of the bile duct and the reticular epicholedochal plexus lie on the surface. The retropancreatic, hilar and intrahepatic parts of biliary tract has copious supply, but the supraduodenal bile duct has the poorest vascularization and hence susceptible to ischemic changes. Two venous plexuses drain the biliary tract. A fine reticular epicholedochal venous plexus on the wall of the bile duct drains into the paracholedochal venous plexus (also called as marginal veins or parabiliary venous system) which in turn is connected to the posterior superior pancreaticoduodenal vein, gastrocolic trunk, right gastric vein, superior mesenteric vein inferiorly and intrahepatic portal vein branches superiorly. These pericholedochal venous plexuses constitute the porto-portal collaterals and dilate in portomesenteric venous obstruction forming the portal cavernoma.

Abstract
Portal cavernoma cholangiopathy (PCC) is defined as abnormalities in the extrahepatic biliary system including the cystic duct and gallbladder with or without abnormalities in the 1st and 2nd generation biliary ducts in a patient with portal cavernoma. Presence of a portal cavernoma, typical cholangiographic changes on endoscopic or magnetic resonance cholangiography and the absence of other causes of these biliary changes like bile duct injury, primary sclerosing cholangitis, cholangiocarcinoma etc are mandatory to arrive a diagnosis. Compression by porto-portal collateral veins involving the paracholedochal and epicholedochal venous plexuses and cholecystic veins and ischemic insult due to deficient portal blood supply or prolonged compression by collaterals bring about biliary changes. While the former are reversible after porto-systemic shunt surgery, the latter are not. Majority of the patients with PCC are asymptomatic and approximately 21% are symptomatic. Symptoms in PCC could be in the form of long standing jaundice due to chronic cholestasis, or biliary pain with or without cholangitis due to biliary stones. Endoscopic retrograde cholangiography has no diagnostic role because it is invasive and is associated with risk of complications, hence it is reserved for therapeutic procedures. Magnetic resonance cholangiography and portovenography is a noninvasive and comprehensive imaging technique, and is the modality of choice for mapping of the biliary and vascular abnormalities in these patients. PCC is a progressive condition and symptoms develop late in the course of portal hypertension only in patients with severe or advanced changes of cholangiopathy. Asymptomatic patients with PCC do not require any treatment. Treatment of symptomatic PCC can be approached in a phased manner, coping first with biliary clearance by nasobiliary or biliary stent placement for acute cholangitis and endoscopic biliary sphincterotomy for biliary stone removal; second, with portal decompression by creating portosystemic shunt; and third, with persistent biliary obstruction by performing second-stage biliary drainage surgery such as hepaticojejunostomy or choledochoduodenostomy. Patients with symptomatic PCC have good prognosis after successful endoscopic biliary drainage and after successful shunt surgery.

Abstract
Portal hypertensive biliopathy (PHB) is characterized by anatomical and functional abnormalities of the intrahepatic, extrahepatic and pancreatic ducts, in patients with portal hypertension associated to extrahepatic portal vein obstruction and less frequently to cirrhosis. These morphological changes, consisting in dilatation and stenosis of the biliary tree, are due to extensive venous collaterals occurring in an attempt to decompress the portal venous blockage. It is usually asymptomatic until it progresses to more advanced stages with cholestasis, jaundice, biliary sludge, gallstones, cholangitis and finally biliary cirrhosis. Imaging modalities of the biliary tree such as Doppler ultrasound, computed tomography, magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography are essential to establish the diagnosis and the need of therapeutical interventions. Once the diagnosis is established, treatment with ursodesoxycholic acid seems to be beneficial. Decompression of the biliary tree to dilate, remove stones or implant biliary prosthesis by endoscopic or surgical procedures (hepato-yeyunostomy) usually resolves the cholestatic picture and prevents septic complications. The ideal treatment is the decompression of the portal system, with transjugular intrahepatic porto-systemic shunt or a surgical porto-systemic shunt. Unfortunately, few patients will be candidates for these procedures due to the extension of the thrombotic process. The purpose of this paper is to report the first 3 cases of PHB seen in a Colombian center and to review the literature.

Abstract
Presence of portosystemic collateral veins (PSCV) is common in portal hypertension due to cirrhosis. Physiologically, normal portosystemic anastomoses exist which exhibit hepatofugal flow. With the development of portal hypertension, transmission of backpressure leads to increased flow in these patent normal portosystemic anastomoses. In extrahepatic portal vein obstruction collateral circulation develops in a hepatopetal direction and portoportal pathways are frequently found. The objective of this review is to illustrate the various PSCV and portoportal collateral vein pathways pertinent to portal hypertension in liver cirrhosis and EHPVO.

Abstract
Portal biliopathy refers to biliary abnormalities secondary to extrahepatic portal vein obstruction and cavernous transformation and is caused by vascular compression from peribiliary collateral vessels, producing segmental stenoses of the common bile duct and abnormal liver function test (LFT) results. A review of imaging studies yielded 18 patients with abnormal LFT results, biliary tract dilatation, and extrahepatic portal vein obstruction with cavernous transformation. Multidetector computed tomography and magnetic resonance imaging showed biliary stenotic segments in 11 patients secondary to extrinsic compression from enlarged peribiliary collaterals. Clinical and imaging follow-up demonstrated improvement in LFT results with minimal decrease in bile duct dilatation, eliminating percutaneous or endoscopic biliary intervention.

Abstract
MRCP is a non-invasive cholangiographic technique used in detection and characterization of bile ducts abnormalities. MRCP features of primary sclerosing cholangitis are randomly distributed annular strictures alternating with slightly dilated bile ducts. Secondary sclerosing processes including ascending, ischemic, caustic, AIDS-related, eosinophilic and autoimmune cholangitis can mimic PSC at MRCP.

Abstract
PURPOSE To compare the anatomic and clinical features in patients with chronic portal vein thrombosis (PVT) to determine why some patients develop portal biliopathy (PB) while most do not and propose an etiology for PB. MATERIALS AND METHODS This project satisfied HIPAA regulations and received institutional review board approval for a retrospective review without the need for consent. From 100 patients with PVT, 60 were extracted who had chronic, nonmalignant PVT, after exclusion of those with sclerosing cholangitis, liver transplants, choledocholithiasis, or portosystemic shunts. Clinical and imaging data from 19 patients with biliary dilatation (PB group) were compared with data from 41 patients without biliary dilatation (no-PB group). Statistical analysis was performed with the Fisher exact test for categorical variables or the Wilcoxon rank-sum test for numerical and ordered categorical variables. P values of .05 or less were considered to indicate a significant difference. RESULTS The etiology of PVT differed between the groups (P < .001); cirrhosis was infrequently seen in the PB group (two of 19, 11%) but was common in the no-PB group (31 of 41, 76%). Only two of 33 (6%) patients with cirrhosis and PVT had PB. Extension of PVT into the mesenteric veins was significantly more common in the PB group (18 of 19, 95%) than in the no-PB group (one of 41, 2%) (P < .001). Compared with the no-PB group, patients in the PB group had more acute angulation of the bile duct (median, 110° vs 128°; P = .008), less frequent gastroesophageal varices (three of 19 [16%] vs 20 of 41 [49%], P = .021), and a smaller mean coronary vein diameter (median, 5 vs 6 mm; P = .014). CONCLUSION Noncirrhotic patients with hypercoagulable states tend to develop PB when PVT extends to the splenomesenteric veins. A possible etiology is the formation of specific peribiliary venous pathways responsible for bile duct compression and tethering.

Abstract
Portal hypertensive biliopathy (PHB) refers to abnormalities of the entire biliary tract including intrahepatic and extrahepatic bile ducts, cystic duct and gallbladder in patients with portal hypertension. The pathogenesis of PHB is not clearly known and it has been postulated that external pressure by dilated veins of portal cavernoma and/or ischaemic strictures of the bile duct may play a role. Approximately 20% of patients are with symptoms of biliary system, which is associated with higher age, longer duration of diseases, higher frequency of common bile duct (CBD) stones and gallbladder stones, and abnormal liver function. Magnetic resonance (MR) cholangiography and MR portography are the initial choice of investigation in the evaluation of PHB. Endoscopy or surgical method is optional to treat patients with symptoms, aiming at management of portal hypertension and relief of obstructive jaundice.

Abstract
PURPOSE To investigate the imaging features of portal biliopathy with emphasis on MR cholangiopancreatography (MRCP). The ancillary vascular findings of portal biliopathy were also evaluated by accompanying MR portography, dynamic contrast-enhanced (CE) CT, and dynamic CE MRI studies. MATERIALS AND METHODS Sixteen patients with portal cavernoma were included in the study. Patients had undergone MRCP (n=16) studies accompanied by MR portography (n=13), dynamic CE CT (n=3) or dynamic CE MRI (n=2) of the liver. Two patients had undergone both dynamic CE CT and dynamic CE MRI. Two radiologists evaluated all the examinations together, retrospectively. MRCP images were analyzed for the presence of biliary stenosis, upstream (prestenotic) dilatation, wavy appearance of the bile ducts, angulation of the common bile duct (CBD), and choledocholithiasis. MR portography, dynamic CE CT and dynamic CE MRI studies were evaluated for the existence of portal cavernomas, and the presence of gall bladder/choledochal varices. RESULTS All patients had signs of portal biliopathy on MRCP. Frequencies of the biliary findings on MRCP were as follows: biliary stenosis, 93.7%; upstream dilatation, 68.7%; wavy appearance of the biliary tree, 87.5%; angulation of the CBD, 75%. None of the patients had choledocholithiasis. Frequencies of the ancillary vascular findings detected on CE studies were as follows: gall bladder varices, 100%, choledochal varices, 93.7%. CONCLUSION MRCP features of portal biliopathy in order to their frequencies were as follows: biliary stenosis, wavy appearance of the bile ducts, angulation of the CBD, and upstream dilatation of the bile ducts.

Abstract
Major surgical resection is often the only curative treatment for cholangiocarcinoma. When imaging techniques fail to establish the accurate diagnosis, biopsy of the lesion is unavoidable. However, biopsy is not necessarily required for topography of the cholangiocarcinoma (intrahepatic or extrahepatic). 1) In extrahepatic cholangiocarcinoma (ECC), clinical features and radiological imaging relate to biliary obstruction. Provided that between 8% and 43% of bile duct strictures are not ECC, the lesions mimicking ECC that should be ruled out are gallbladder cancer, Mirizzi syndrome, primary sclerosing cholangitis (PSC), autoimmune pancreatitis and portal biliopathy. Systematic biopsy is usually difficult and has poor sensitivity, but a good knowledge of these mimicking ECC diseases, along with precise analysis of clinical and imaging semiology, may lead to a correct diagnosis without the need for biopsy. 2) Intrahepatic cholangiocarcinoma (ICC) developing in normal liver appears as a hypovascular tumour with fibrotic component and capsular retraction that can be confused with fibrous metastases such as breast and colorectal cancers. The lack of the primary site, a relatively large tumour size and ancillary findings such as bile duct dilatation may provide a clue to the diagnosis. If not, we advocate local resection with lymph node dissection, since ICC is the most likely diagnosis and surgery is the only curative treatment. In the event of adenocarcinoma from unknown primary, surgery is an effective treatment even if prognosis is poor.

Abstract
OBJECTIVE We present our experiences with infraportal bile duct of the caudate lobe (B1) and discuss surgical implications of this rare variation. SUMMARY BACKGROUND DATA Although various authors have investigated biliary anatomy at the hepatic hilum, an infraportal B1 (joining the hepatic duct caudally to the transverse portion of the left portal vein) has not been reported. METHODS Between January 1981 and December 2005, 334 patients underwent hepatectomy combined with caudate lobectomy for perihilar cholangiocarcinoma. Four of them (1.2%) had infraportal B1 and were investigated clinicoanatomically. RESULTS All infraportal B1 were B1l, draining Spiegel's lobe; no infraportal B1r (draining the paracaval portion) or B1c ducts (draining the caudate process) were found. The infraportal B1l joined the common hepatic duct or the left hepatic duct. Three patients underwent right trisectionectomy with caudate lobectomy; for one, in whom preoperative diagnosis was possible, combined portal vein resection and reconstruction were performed before caudate lobectomy to resect the caudate lobe en bloc without division of infraportal B1. For the other 2 patients, the infraportal B1 was divided to preserve the portal vein, and then the caudate lobe was resected en bloc. The fourth patient underwent right hepatectomy with right caudate lobectomy; the cut end of the infraportal B1 showed no cancer by frozen section, so the bile duct was ligated and divided to preserve the left caudate lobe. CONCLUSION Infraportal B1 can cause difficulties in performing right-sided hepatectomy with caudate lobectomy or harvesting the left side of the liver with the left caudate lobe for transplantation. Hepatobiliary and transplant surgeons should carefully evaluate biliary anatomy at the hepatic hilum, keeping this variation in mind.
