Newly diagnosed base of tongue cancer status post excisional biopsy and left neck lymph node. There is an enhancing mass in the left tongue base, which measures up to 22 mm. The tumor abuts the left styloglossus muscle, but does not invade the pterygoid musculature. The tumor does not extend across the midline. There is an enlarged left level 2A lymph node, which measures 12 x 26 mm in axial cross-section. There appears to be associated infiltration of the left sternocleidomastoid muscle. Other cervical lymph nodes are not particularly enlarged. The thyroid and salivary glands are unremarkable. There is a disc-osteophyte complex at C5-6, which mildly indents the spinal cord. There is a subcutaneous cystic lesion in the posterior left neck, which measures up to 15 mm, with surrounding inflammatory changes. There is fluid within the right maxillary sinus. The orbits and imaged intracranial structures are unremarkable.
1. A left tongue base mass that measures up to 22 mm is compatible with squamous cell carcinoma, although superimposed biopsy effects can confound the extent of disease.2. An enlarged left level 2A lymph node likely represents metastatic disease, perhaps with extracapsular extension. 3. Findings suggestive of acute right maxillary sinusitis.4. Inflamed inclusion or sebaceous cyst in the left posterior neck.
