Eethesioneuroblastoma; received 2 cycles of chemotherapy; assess for response to therapy. Face: There is a right sinonasal mass that extends from medial maxillary sinus, through the infundibulum into the middle meatus and anterior ethmoid air cells. The tumor measures up to approximately 30 mm in craniocaudal extent, 30 mm in the anteroposterior dimension, and 20 mm transversely, which is similar to the size of the tumor in August 2015. There are obstructed secretions and mucosal thickening in the right maxillary sinus, frontoethmoid, frontal sinuses. There is apparent dehiscence of the posterior wall of the right nasolacrimal duct, which appears narrowed, but no evidence of intracranial or intraorbital extension of the tumor. There appears to be a mildly asymmetrically prominent right level 2B lymph node. There is leftward nasal septal deviation. There is a subcentimeter probable nasopharyngeal retention cyst.Brain: There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is a prominent perivascular space in the right basal ganglia. The brain parenchyma otherwise appears unremarkable. There is no 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. The orbits, skull, and scalp soft tissues are grossly unremarkable.
1. A right sinonasal mass measuring up to 30 mm that involves the right maxillary, middle meatus, and ethmoid sinuses is compatible with residual esthesioneuroblastoma without evidence of intraorbital or intracranial extension. 2. A mildly asymmetrically prominent right level 2B lymph node is nonspecific.3. No evidence of intracranial hemorrhage, mass, or acute infarct.
