<prompt> Please answer with one of the option in the bracket. Write reasoning in between . Write answer in between .Q:A 65-year-old man is brought to the emergency department because of a fall that occurred while he was taking a shower earlier that morning. His wife heard him fall and entered the bathroom to find all four of his extremities twitching. The episode lasted approximately 30 seconds. He was unsure of what had happened and was unable to answer simple questions on awakening. He has regained orientation since that time. He has hypertension and hyperlipidemia. Current medications include metoprolol and atorvastatin. His temperature is 37.1C 98.8F, pulse is 72min, respirations are 19min, and blood pressures is 13080 mm Hg. Pulse oximetry on room air shows an oxygen saturation of 98. Cranial nerve examination shows no abnormalities. He has 55 strength in all extremities. Examination shows full muscle strength. Sensation to pinprick, light touch, and vibration is normal and symmetrical. A noncontrast head CT is performed and shows a slightly hyperdense mass. Follow-up MRI shows a homogeneous, well-circumscribed 4-cm mass with compression of the adjacent white matter, and a hyperintense rim around the mass on T2 weighted imaging. Which of the following is the most likely diagnosis?? A: Glioblastoma multiforme, B: Oligodendroglioma, C: Schwannoma, D: Hemangioblastoma, E: Meningioma,  <response>: Based on the information provided in the question stem, this appears to be a case involving a 65-year-old man who experienced a transient episode of extremity twitching and confusion after a fall in the shower. His medical history is significant for hypertension and hyperlipidemia. Initial workup showed normal vital signs, cranial nerves, strength, and sensation. A head CT showed a hyperdense mass, and subsequent MRI showed a well-circumscribed, homogeneous mass with compression of adjacent white matter and a hyperintense rim around the mass on T2 imaging. The description of the imaging findings narrows down the differential diagnosis. The MRI findings of a homogeneous, well-circumscribed mass with a hyperintense rim on T2 imaging are classic for meningioma. Glioblastoma multiforme would appear heterogeneous and invasive on imaging. Oligodendroglioma and schwannoma would not cause the hyperintense rim. Hemangioblastoma is a less likely possibility given the patients age.E: Meningioma
