Neck mass. There is a rather ill-defined lesion in the right submental subcutaneous tissues that measures up to approximately 2 cm beneath the skin marker. The lesion demonstrates diffuse enhancement and contains areas of low T1 and T2 signal. There is no evidence of measurable mass lesions or significant cervical lymphadenopathy based on size criteria. The thyroid and major salivary glands are unremarkable. The osseous structures are unremarkable. The imaged intracranial structures, paranasal sinuses, and orbits are unremarkable.
Differential considerations for the lesion in the right submental subcutaneous tissues that measures up to approximately 2 cm include vascular malformations, fibromatosis, or neoplasm. An ultrasound of the lesion with Doppler may be useful for further evaluation.
