The introduction of microbubble contrast agents (CA), which act as blood pool tracers, has overcome the limitations of conventional B-Mode, colour or power Doppler ultrasound, enabling the display of parenchymal microvasculature. Initially, the use of CA was accepted for hepatic lesions. In the following years, experts have expanded recommendations, as a result of the method's efficiency in extrahepatic applications. In this article we review the methodology and the application of contrastenhanced ultrasound (CEUS) in the evaluation of biliary pathology. This new imaging tool allows a non invasive differential diagnosis of biliary lesions and a clearer delineation of the tumoral process.

“…Nunoi H et al [11] described a patient with PB-associated with the morphological abnormality of the biliary duct and GB associated with PH that presented with essential thrombocythemia, initially diagnosed with extrahepatic portal vein obstruction. The contrast-enhanced CT findings were similar to those of cholangiocarcinoma or sclerosing cholangitis.…”

“…Presently there is no role for intravenous cholangiography. Shin SM in their study of MRI features of PB showed that MR cholangiography and 3D gradient-echo imaging not only detect portal vein occlusion, but cavernous transformation, and GB varices and other associated bile duct abnormalities [4]- [11].…”

Aim: To discuss the etiology, pathogenesis, diagnosis and management of PB, supported by a series of 9 cases from a personal series. Methods: Radiological images of 9 cases of PB were retrieved from different hospitals and studied and information relating to PB was obtained from various internet databases including PUB Med, Google, Google Scholar and Educus. Results: Portal biliopathy (PB) is a rare complication of extra-portal venous obstruction. Most patients remain asymptomatic, but some may present with raised alkaline phosphatase level, abdominal pain, fever, and cholangitis. It tends to be associated with gallbladder (GB) wall abnormalities, a cavernous transformation of the portal vein and choledochal varices. Extrinsic compression of the common bile duct, (CBD), by dilated venous collaterals together with pericholedochal fibrosis from the inflammatory process can cause portal thrombosis, which may lead to biliary stricture and dilatation of the proximal biliary tree. These strictures set the scene for formation biliary stones and cholangitis. Liver function test abnormalities are common but remain non-specific. Imaging features are instrumental in the diagnosis of PB. This paper presents 9 of such cases of portal biliopathy, with discussions on their causation, the course of the disease process and management particularly minimally invasive procedure. The role of ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), endoscopic retrograde cholangiopancreatography (ERCP) and direct puncture cholangiography is discussed. Surgical management is evaluated. An imaging atlas is provided. Conclusions: PB is a rare but significant complication of portal venous obstruction that has an insidious onset and may remain asymptomatic until late. PB has associated coagulopathies, and a variety of other disorders, which are discussed, illustrated and the diagnosis-elaborated. The role of MRI as a non-invasive imaging tool is emphasized.

“…Findings of PTB and EHPVO can be well described by colour Doppler flow imaging, endoscopic retrograde cholangiopancreaticography (ERCP), CECT and MRI [27][28][29]. We diagnosed this case with MRCP and CECT portovenography [30,31].…”

Extra-hepatic portal venous obstruction is most common cause of portal hypertension in children. Apart from variceal formation in gastric and esophageal mucosal layer, it has been postulated that external pressure and or ischemic injury play a role in portal biliopathy. We report an unusual case of a 6 month old infant who presented to us with clinical features suggestive of extra-hepatic biliary atresia; diagnosed as EHPVO with portal biliopathy, managed surgically.
