Case report of portal hepatic schwannoma: presentation of multimodality images

摘要

a Contrast-enhanced CT shows a clavate-shaped periportal tumor with inhomogeneous moderate enhancement (arrow). b T2-weighted imaging shows the tumor isointense to fat with cystic degeneration (arrow). c MRCP shows bile duct compression without any biliary dilatation (arrows). d ERCP also shows bile duct compression without any biliary obstruction (arrow). e The tumor has not changed at the 2nd CT (arrow). f PET shows FDG uptake of the tumor (arrow, SUVmax 5.0). SUVmax is increased slightly to 6.5 in the late phase
