• Myoepithelioma
• Image findings
• Magnetic resonance imaging
• Computed tomography

A case of myoepithelioma presumed to have arisen from an accessory parotid gland is reported. Preoperative fine-needle aspiration cytological findings suggested a malignant tumor, possibly an adenoid cystic carcinoma, while histopathological findings acquired during surgical resection revealed a myoepithelioma. The tumor was located adjacent to the Stensen duct, suggesting an accessory parotid gland origin. The diagnostic potential of magnetic resonance imaging and contrast-enhanced computed tomography in diagnosing this disease is discussed.
