Left salivary duct carcinoma ex pleomorphic adenoma status post chemotherapy and left deep lobe parotidectomy and neck dissection with pathology showing metastatic carcinoma in 4/19 lymph nodes. There are post-treatment findings in the neck, including left deep lobe parotidectomy and neck dissection. There is diffuse edema in the remaining portions of the left parotid gland, likely related to treatment effects, but no measurable tumor in the parotidectomy bed. The left submandibular gland also appears to be mildly edematous. The right-sided salivary glands are unremarkable. There is no residual significant cervical lymphadenopathy, including in the supraclavicular regions. The thyroid gland is unremarkable. The osseous structures are intact. There is mild ethmoid and left maxillary sinus mucosal thickening. The imaged intracranial structures are unremarkable.
Post-treatment findings in the neck without evidence of measurable residual left parotid tumor or significant cervical lymphadenopathy.
