Newly diagnosed base of tongue cancer. There appears to be an ill-defined lesion in the left tongue base that measures up to approximately 10 to 15 mm, although precise measurement is limited by the il-defined nature of the lesion. There does not appear to be extension into the oral tongue, glossotonsillar sulcus, masticator space, or parapharyngeal space. There is no evidence of significant cervical lymphadenopathy. The thyroid and major salivary glands are unremarkable. The osseous structures are grossly intact. The imaged intracranial structures are unremarkable.
An ill-defined lesion in the left tongue base is compatible with invasive squamous cell carcinoma. No evidence of significant lymphadenopathy in the neck.
