Right parotid mass, possible lipoma. History of completion thyroidectomy with neck dissection and mediastinal mass excision for metastatic medullary thyroid cancer. The patient also had a right buccal space tumor excised from right parotidectomy approach in 2012. There are postoperative findings related to partial right parotidectomy. There is a well-defined ovoid fat signal structure that contains vessels anterior to the right parotid gland. The lesions measures 31 x 15 mm in the axial cross-section, which appears to be similar in size compared to prior exams, accounting for differences in positioning. The remaining portions of the salivary glands are otherwise unremarkable. There is no measurable buccal mucosa tumor. There are postoperative findings related to thyroidectomy, without evidence of recurrent tumor in the thyroidectomy bed. There are postoperative findings related to neck dissection, without evidence of significant cervical lymphadenopathy. There is multilevel degenerative cervical spondylosis. There are partially imaged postoperative changes related to mediastinal mass resection.
1. Postoperative findings related to partial right parotidectomy with what likely represents a lipoma anterior to the remaining portions of the right parotid gland.2. Postoperative findings related to thyroidectomy, without evidence of recurrent tumor in the thyroidectomy bed.
