Abstract
We encountered two cases of epithelialmyoepithelial carcinoma (EMC), a rare low-grade malignant tumor of the parotid gland. These two EMCs showed similar imaging findings: gradual contrast enhancement on dynamic magnetic resonance imaging (MRI), intense 18F-fluorodeoxyglucose (FDG) uptake in the solid tumor portion, and little enhancement and little FDG uptake in the hemorrhagic necrotic tumor portion. When a parotid gland tumor shows gradual MRI contrast enhancement and focally intense FDG uptake, EMC should be included in the differential diagnosis.
