"Bump" in the right side of her oral cavity possibly due to a venous mass. MRI: There is an asymmetrically prominent right anterior jugular vein that courses lateral to the submandibular gland. The right internal jugular vein appears diminutive throughout the expected course of the vessel. Otherwise, the oral cavity contents are unremarkable and there is no evidence of measurable mass lesions or significant cervical lymphadenopathy. The thyroid and major salivary glands are unremarkable. The osseous structures are unremarkable. The imaged intracranial structures are unremarkable. MRA: There is no evidence of significant steno-occlusive lesions of the major cervical arteries.
An asymmetrically prominent right anterior jugular vein that courses lateral to the submandibular gland represents an anatomic variant rather than a malformation and may be compensating for a diminutive right internal jugular vein. Otherwise, no evidence of tumors or significant lymphadenopathy in the neck.
