 BRAIN: There is interval decrease in size of the infiltrative enhancing mass centered within the nasopharynx and skull base. The tumor is ill-defined and measures approximately 4 cm, previously approximately 7 cm. There is also nonspecific confluent enhancement extending laterally into the bilateral masticator spaces and pterygopalatine fossae. In addition, there is diffuse enhancement within the clivus and sinonasal walls. There is persistent, but decreased involvement of the cavernous sinuses with encasement of the carotid arteries. The abnormal enhancement along the planum sphenoidale and within the sella is also markedly reduced and perhaps resolved. There is no evidence of brain parenchymal involvement. There has been interval decrease in size of the left level 2A and bilateral retropharyngeal lymph nodes. There is mild mucosal thickening throughout the paranasal sinuses and fluid within the bilateral mastoid air cells. There are unchanged nonspecific patchy foci of T2 hyperintensity throughout the supratentorial white matter and pons that may represent chronic small vessel disease or post-treatment effects. There is no evidence of acute infarct. The ventricles and basal cisterns are unchanged in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. ORBITS: Intraorbital extension of the tumor has subsided bilaterally.
Post-treatment findings with interval decrease in size of the infiltrative nasopharyngeal carcinoma and associated lymphadenopathy. Please refer to the concurrent neck CT for additional details.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
