Anterior neck mass with abnormal CT scan finding of possible lymphatic malformation. There is a multiloculated fluid signal mass with mild diffuse peripheral enhancement in the anterior right neck that insinuates along the facial planes anterior to the sternocleidomastoid muscle and into the submandibular and deep parotid spaces measuring up to approximately 8 cm in length. There is no evidence of significant cervical lymphadenopathy based on size criteria. The left salivary glands are unremarkable. There is a punctate cystic nodule in the right thyroid gland. The osseous structures are intact. The imaged intracranial structures and orbits are unremarkable. The imaged portions of the lungs are clear.
A cystic mass in the anterior right neck that insinuates along the facial planes anterior to the sternocleidomastoid muscle and into the submandibular and parotid spaces measuring up to approximately 8 cm in length likely represents a macrocystic lymphatic malformation.
