History of HTN, HLD, SLE, DVT with positive lupus anticoagulant with right submandibular region swelling. There is persistent asymmetric enlargement of the right submandibular gland, perhaps with a nodular area inferiorly, but no significant ductal dilatation. There are also enlarged right submandibular lymph nodes, but the left cervical lymph nodes do not appear to be particularly enlarged. The left submandibular and bilateral parotid glands are unremarkable. The thyroid gland is unremarkable. The osseous structures appear to be intact. The orbits, paranasal sinuses, and upper aerodigestive tract are unremarkable. There is diffuse cerebral volume loss and scattered areas of cerebral white matter T2 hyperintensity.
Persistent asymmetric enlargement of the right submandibular gland and enlarged right submandibular lymph nodes. Differential considerations include an autoimmune process versus neoplasm.
