Previous right tonsil cancer. Biopsy in July 2016 yielded fibrosis and chronic inflammation, negative for carcinoma. There are postoperative findings in the right tongue base region. There appears to be a somewhat ill-defined persistent area of enhancement in the right tonsillar sulcus and posterior tongue region, which measures up to 20 mm. There is a small retropharyngeal effusion. There is no significant cervical lymphadenopathy based on size criteria. The thyroid and major salivary glands are unremarkable. There is mild multilevel degenerative spondylosis. The imaged intracranial structures and orbits are unremarkable. There is a small amount of fluid in the right mastoid air cells.
Postoperative findings with a persistent area of enhancement in the right tonsillar sulcus and posterior tongue region, which may represent recurrent tumor and/or treatment effects. Otherwise, no evidence of significant cervical lymphadenopathy based on size criteria.
