Overview
On ultrasound, characteristic findings of mucoepidermoid carcinoma include: a well-circumscribed hypoechoic lesion with a partial or completely cystic appearance, in contrast to the relatively hyperechoeic normal parotid gland.
Ultrasound
- Ultrasound findings associated with mucoepidermoid carcinoma include:[1]
New technologies, including high-resolution probes and harmonic imaging, can delineate location, homogeneity or heterogeneity, shape, vascularity, and margins of salivary tumors in the periauricular, buccal, and submandibular area.
Ultrasonography may be able to reveal the type of tumor, [5] and new ultrasonographic contrast mediums can now demonstrate the vascularity of the tumor before surgery.[2]
A study by Rong et al identified differences between the ultrasonographic characteristics of Warthin tumors and those of pleomorphic adenomas, including with regard to shape, vascularity, and the prevalence of cystic areas.[3]
