Case list for Primary Sclerosing Cholangitis (PSC)
There are 2 CT cases with this diagnosis.
Peripheral regenerative nodule anteriorly in segment 4A in a patient with primary sclerosing cholangitis: The central portal venous vessel is typical and allows this regenerative nodule to be distinguished from a neoplasm ("vessel penetration sign"). Also the enhancement equal to the remainder of the parenchyma throughout all contrast phases characterizes the nodule as part of the hepatic parenchyma.
Typical pattern of hepatic atrophy and regeneration on CT representing primary sclerosing cholangitis (PSC): predominance of peripheral segmental atrophy with complete shrinkage of the right lobe, and compensatory hypertrophy of central segments including the caudate lobe. Differences of biliary calibers, typical for this disease, are not well appreciated on this set of images.
