Overview

On MRI, characteristic findings of mucoepidermoid carcinoma will depend on the stage. Common findings include: low signal cystic spaces in T1, and high signal in cystic areas on T2.[1]


MRI

  • MRI findings associated with mucoepidermoid carcinoma, include:[1]
  • T1: low to intermediate signal; low signal cystic spaces
  • T2: intermediate to high signal; cystic areas will be high signal
  • T1 C+ (Gd): heterogeneous enhancement of solid components
  • High grade tumours on the other hand have lower signal on T2 and poorly defined margins and infrequent cystic areas:
  • T1: low to intermediate signal
  • T2: intermediate to low sign
