Pleomorphic adenoma MRI

Introduction

Overview

Overview

MRI is the imaging modality of choice for pleomorphic adenoma. The findings on T1-weighted images are homogeneous intensity while on T2 it shows marked hyperintensity which reflects abundant myxochondroid stroma. On Gd-T1 it shows heterogeneous enhancement.
