Left tonsil cancer treated with induction chemotherapy: the recent CT was limited by dental artifact. Need to reevaluate oropharyngeal area for response. There is marked decrease in size of the left tonsil mass compared with the pre-induction CT. Indeed, the treated tumor now measures up to approximately 10 mm. There is no significant lymphadenopathy in the neck. The thyroid and major salivary glands are unremarkable. There is a left cerebellomedullary angle arachnoid cyst that measures up to 18 mm, with mild mass effect upon adjacent structures. There is mild bilateral maxillary sinus mucosal thickening. The orbits are unremarkable. There is a right apical lobe patchy consolidation and left apex tree-in-bud nodularity.
1. Marked decrease in size of the left tonsil mass compared with the pre-induction CT. Indeed, the treated tumor now measures up to approximately 10 mm. 2. No significant lymphadenopathy in the neck.3. A left cerebellomedullary angle arachnoid cyst measures up to 18 mm, with mild mass effect upon adjacent structures. 4. Right apical lobe patchy consolidation and left apex tree-in-bud nodularity may be related to sarcoidosis. Please refer to the recent chest CT report for additional details.
