Portal biliopathy diagnosed using color Doppler and contrast-enhanced ultrasound.
Portal biliopathy is a morphological abnormality of the biliary ductal and gallbladder wall associated with portal hypertension. A patient with essential thrombocythemia was initially diagnosed with extrahepatic portal vein obstruction (EHPVO). The contrast-enhanced computed tomography (CT) findings were similar to those of cholangiocarcinoma or sclerosing cholangitis. However, color Doppler an...
متن کاملPortal biliopathy.
Portal biliopathy (PB) is a rare disorder, which mostly presents as sub-clinically. It occurs most commonly due to idiopathic extrahepatic portal vein obstruction. We present three cases having features of portal biliopathy secondary to portal hypertension. Our first case did not have a prior history of chronic liver disease while next two patients had previous history of chronic liver disease ...
متن کاملPortal biliopathy
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 ...
متن کاملCholecystoduodenal fistula diagnosed with contrast-enhanced endoscopic ultrasound.
A 58-year-old man with a history of Crohn’s disease (A2L2B1p), bile stones, migraine, and chronic depression presented with an 11-kg weight loss and asthenia during the preceding 6 months. He was receiving treatment with infliximab, azathioprine, mirtazapine, and lorazepam. Laboratory tests showed a slightly elevated C-reactive protein (CRP) of 35mg/dL. He underwent a computed tomography (CT) s...
متن کاملContrast-enhanced endoscopic ultrasound.
Compared to other imaging modalities, endoscopic ultrasound (EUS) has limitations in terms of image enhancement. However, with the availability of contrast agents in ultrasonography, EUS has evolved. Contrast-enhanced Doppler EUS (CD-EUS) enhances Doppler signals from vessels and is useful for characterizing lesions detected by EUS. Moreover, contrast-enhanced harmonic EUS (CH-EUS) with second-...
