Recurrent T2N2B squamous cell carcinoma of the base of the tongue, previously treated with concurrent cisplatin/RT and now receiving chemotherapy. There is an ill-defined ulcerative lesion centered in the left tongue base with extension into the glossotonsillar sulcus that measures up to 40 mm in length and 10 mm in thickness. There is diffuse edema within the supraglottic suprahyoid soft tissues of the upper aerodigestive tract, overlying skin, as well as the left submandibular gland. There is denervation change involving the left hemitongue. There is no evidence of significant cervical lymphadenopathy based on size criteria. There are multilevel posterior cervical disc-osteophyte complexes that narrow the spinal canal. The imaged intracranial structures and orbits are unremarkable. There is minimal scattered paranasal sinus mucosal thickening.
1. Extensive treatment effects in the upper aerodigestive tract region with an ill-defined ulcerative lesion centered in the left tongue base with extension into the glossotonsillar sulcus, which likely represents treated tumor. 2. No residual significant lymphadenopathy in the neck.
