Esthesioneuroblastoma status pot resection with SIADH prior resection, now with low sodium again. Face: There are post-operative findings related to right medial maxillectomy and right anterior and posterior ethmoidectomy. There is no significant change in the enhancement within the right frontoethmoid treatment bed with small areas of low T2 signal. There is persistent mucosal thickening in the right maxillary sinus. There is no evidence of measurable tumor in the treatment bed. There is leftward nasal septal deviation. There are findings related to right dacryocystorhinostomy, but the orbits are otherwise grossly intact. There is a subcentimeter Thornwaldt or nasopharyngeal retention cyst.Brain: There is no evidence of intracranial extension of tumor. There is an unchanged prominent perivascular space in the right basal ganglia. The brain parenchyma otherwise appears unremarkable and there is no evidence of acute infection or abnormal intracranial enhancement. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact.
1. FINdings related to right sinonasal surgery with a persistent small area in the right superior anterior ethmoid surgical bed that has some features that resemble the original tumor, but is otherwise nonspecific. Perhaps PET would be useful for further evaluation.2. No evidence of intracranial tumor.
