History of left parotid surgery for resection of an oncocytoma. History of papillary thyroid cancer, colon cancer, and left submandibular gland pleomorphic adenoma, as well. There is a slightly irregularly-marginated, enhancing, nodular lesion in the deep lobe of the left parotid gland, just posteromedial to the retromandibular vein, which measures up to 9 mm. There is a nonspecific prominent right retropharyngeal lymph node that measures 5 mm in short axis. There is no evidence of other mass lesions of lymphadenopathy elsewhere in the neck. The right parotid gland and bilateral submandibular glands are unremarkable. There has been total thyroidectomy. The pharyngeal and laryngeal structures are unremarkable. The orbits and imaged portions of the intracranial structures are unremarkable. There is a small posterior disc-osteophyte complex at C5-C6, which abuts the spinal cord.
A subcentimeter nodular lesion in the deep lobe of the left parotid gland may represent recurrent oncocytoma.
