History of recurrent squamous cell carcinoma of the right face involving the parotid gland. There are postoperative findings related to right parotidectomy with flap reconstruction. There is tumor along the right trigeminal nerve in the parapharyngeal space. The tumor measures up to approximately 30 mm in length and 7 mm in width. The tumor extends towards the foramen ovale, but there is no definite intracranial extension. There are denervation changes in the right masticator muscles. There are bilateral lens implants. There is no evidence of significant cervical lymphadenopathy. There is a chronic left basal ganglia infarct.
Postoperative findings related to right parotidectomy with flap reconstruction with evidence of perineural tumor spread along the right trigeminal nerve into foramen ovale and associated right masseter muscle denervation. However, characterization is limited due to the lack of intravenous contrast.
