History of poorly differentiated sinonasal carcinoma SNUC treated with CRT. There are postoperative findings related to sinonasal tumor excisional biopsy with resection of the left ostiomeatal complex and left middle and superior turbinates. There is no evidence of measurable sinonasal region tumor. There is persistent mucosal thickening and secretions that occupy the left sphenoid sinus. There is also persistent moderate mucosal thickening in the left maxillary sinus and mild mucosal thickening within the right maxillary, right sphenoid, left frontal, and right ethmoid sinuses. The parotid glands are unremarkable. There is encephalomalacia in the inferior right cerebellar hemisphere. There are also scattered nonspecific foci of T2 hyperintensity in the cerebral white matter. There are bilateral lens implants. There is multilevel degenerative cervical spondylosis.
1. Post-treatment findings in the sinonasal region with persistent diffuse mucosal inflammatory changes, but no evidence of measurable tumor recurrence. 2. Chronic right inferior cerebellar infarct.
