T2N2b p16 positive left tonsil squamous cell carcinoma. There is an enhancing mass within the left tonsillar fossa that measures up to 37 mm. There is no extension of tumor into the parapharyngeal space, masticator space, tongue base, or soft palate. There is left level 2B lymphadenopathy with corresponding hypermetabolism on PET, including a lymph node that measures 25 x 30 mm in axial section and another that measures 12 x 20 mm in axial section. There is no significant lymphoadenopathy in the right neck by size criteria. The imaged portions of the thyroid and major salivary glands are unremarkable. The nasopharynx appears to be intact. There is mild multilevel degenerative cervical spondylosis and subcentimeter neural foraminal perineural cysts. There is mild mucosal thickening in the left maxillary sinus. The imaged intracranial structures are unremarkable.
1. An enhancing mass within the left tonsillar fossa that measures up to 37 mm is compatible with squamous cell carcinoma. 2. Left level 2B lymphadenopathy with corresponding hypermetabolism on PET is compatible with metastatic disease.
