Ultrasound

The ultrasound images demonstrate a well-circumscribed ovoid homogeneously hypoechoic cystic lesion with internal debris and posterior acoustic enhancement. This cystic lesion is separated from the adjacent submandibular gland (SMG).

The previously described cystic lesion appears lobulated of slightly high signal on TWI, high signal on T2WI with thick enhancing wall on postcontrast sequences, and restricted diffusion on DWI/ADC.

Small enlarged lymph nodes are noted.
