Thyroid cancer, enlargement of left submandibular gland. Benign salivary gland tissue (ductal and acinar cell groups) in a background ofblood- possible chronic sialadenitis There is a well-defined enhancing mass along the posterior aspect of the left submandibular gland that measures up to 11 mm. The right submandibular gland is unremarkable. There is fatty replacement of the right parotid gland. The left parotid gland is unremarkable. There are postoperative findings related to thyroidectomy. There appears to be an enhancing nodular lesion in the right tracheoesophageal groove that measures up to 12 mm. There is also a mildly prominent left level 4 lymph node that measures up to 10 mm. The rest of the cervical lymph nodes appear unremarkable. The osseous structures are grossly intact. The orbits and imaged intracranial structures are grossly unremarkable.
1. A well-defined enhancing mass along the posterior aspect of the left submandibular gland that measures up to 11 mm may represent a salivary gland neoplasm or focal chronic sialoadenitis, such as a Kuttner tumor, as suggested by the prior FNA.2. A nodular lesion in the right thyroidectomy bed region that measures up to 12 mm is nonspecific, but may represent tumor. 3. A mildly prominent left level 4 lymph node that measures up to 10 mm is also nonspecific.
