Info

Fat density lesion (average density of -120 HU) in the right upper neck just below the parotid gland, along the posterolateral aspect of the submandibular gland. No calcifications, solid component or enhancement is seen in it. No compression effects are seen on the adjacent structures. Gross morphology of the parotid and submandibular salivary glands is within normal limits. Multiple small sub centimeter lymph nodes, likely reactive in nature, are seen on both sides of the neck.
