57-year-old female with history of mobile nodule on right jaw line present for at least six years, nonpainful. Grayscale and color ultrasound at the area of the patient's palpable complaint demonstrates a solid mass within the right parotid gland measuring 2.5 x 2.1 cm in maximum diameter with lobulated margins and increased through transmission which is slightly hypoechoic compared to the surrounding gland. Additionally, there is a smaller adjacent lesion along its inferior aspect measuring 1.3 x 0.8 cm, which may represent an exophytic component of the adjacent larger lesion versus a small separate satellite lesion. The remainder of the gland as well as the contralateral parotid are unremarkable.
Solid mass in the right parotid gland as described above, which is nonspecific by ultrasound. Differential considerations include pleomorphic adenoma as well as other neoplasms. CT or MRI may be considered for further evaluation as warranted clinically.
