History of retinoblastoma, esthesioneuroblastoma, and relapsed osteosarcoma, here for chemotherapy. Brain: There are postoperative findings related to craniofacial resection with frontal mesh cranioplasty. There is a heterogeneously enhancing lobulated sinonasal mass that extends into the right pterygopalatine fossa and medial right masticator space. The tumor also appears to bulge slightly into the anterior cranial fossa with associated mild dural thickening and enhancement. Overall, the mass measures up to approximately 6.5 cm. Although the tumor has not significantly changed in size, the signal characteristics of the tumor have evolved. There are retained secretions within the maxillary and sphenoid sinuses, likely attributable to obstruction by the mass. There are minimal nonspecific punctate foci of cerebral white matter T2 hyperintensity. There is no evidence of acute infarction or intracranial hemorrhage. The ventricles are normal in size and configuration. There is new fluid within the right mastoid and middle ear cavities.Orbits: There are postoperative findings related to right enucleation with an orbital prosthesis in position. The tumor once again bulges slightly into the medial and inferior extraconal portions of the right orbit. The left orbit appears to be intact.
1. Postoperative findings in the craniofacial region without significant change in size of the sinonasal mass that extends into the right pterygopalatine fossa, medial right masticator space, and right orbit, where there has been enucleation. The tumor also appears to bulge slightly into the anterior cranial fossa with associated mild dural thickening and enhancement, which may be reactive in nature.2. New fluid within the right mastoid and middle ear cavities may represent otomastoiditis.
