periportal cuffing
an assembly of a small branch of the portal vein, bile duct, and hepatic artery that surround each liver lobule

a liver abscess that can result from the spread of infection from inflammatory conditions such as appendicitis, diverticulitis, cholecystitis, cholangitis, and endocarditis
pyogenic hepatic abscess
the medial segment of the left lobe of the liver
quadrate lobe

sequela
the sonographic sign associated with the appearance of periportal cuffing in which there is an increased echogenicity of the walls of the portal triads
starry sky sign
the therapy for portal hypertension that involves the placement of a stent between the portal veins and hepatic veins to reduce portal systemic pressure
