History of right base of tongue squamous cell carcinoma with likelihood of recurrence. There is an infiltrative enhancing mass centered in the right lateral tongue base, which measures up to approximately 25 mm. The tumor also appears to invade a portion of the oral tongue and extends to the glossotonsillar sulcus. Diffuse edema and enhancement in the adjacent right lateral oropharyngeal and retropharyngeal walls is otherwise likely treatment related and the pterygoid musculature appears to be intact. There is no evidence of significant lymphadenopathy. The thyroid and major salivary glands are unremarkable. There is a deficient inferior right internal jugular vein flow void. There is mild multilevel degenerative spondylosis. The imaged portions of the intracranial structures and orbits are unremarkable.
1. A tumor measuring up to 25 mm centered within the right tongue base likely represent recurrent squamous cell carcinoma in the setting of treatment effects. 2. No evidence of cervical lymph node metastases.
