Treated nasopharyngeal carcinoma with headaches. There is encephalomalacia and susceptibility effect in the left cerebellar hemisphere. There is no evidence of intracranial hemorrhage, mass, or acute infarct. The ventricles are unchanged in size. There are post-treatment findings in the left nasopharyngeal region with soft tissue deficiency involving the pharyngeal mucosal and left parapharyngeal spaces, where there is diffuse enhancement of the residual soft tissues, but no discernible tumor. There is persistent diffuse T2 hyperintensity and enhancement in the central skull base. There are postoperative findings related to left mastoidectomy with fluid in the remaining mastoid air cells. There also a small amount of fluid signal within the right mastoid air cells. There is moderate mucosal thickening involving most of the paranasal sinuses, with possible secretions in the right maxillary sinus. There are bilateral subcentimeter lacrimal gland cysts. The orbits are grossly unremarkable.
1. Chronic infarct in the left cerebellar hemisphere, but no evidence of acute infarction or intracranial tumor.2. Post-treatment findings in the left nasopharyngeal region with no definite evidence of gross tumor.3. Findings related to prior central skull base osteomyelitis and osteoradionecrosis.4. Postoperative findings related to left mastoidectomy with nonspecific fluid in the remaining mastoid air cells.5. Findings suggestive of acute sinusitis.6. Bilateral subcentimeter lacrimal gland cysts.
