Overview

MRI is the study of choice for pleomorphic adenoma. On T1-weighted images they show homogeneous intensity, on T2 they show marked hyperintensity reflecting myxochondroid stroma and hypointensity corresponds to fibrous capsule of the tumor. On Gd-T1 imaging it shows heterogeneous enhancement.
