[{'content': 'A 62-year-old man with a history of poorly controlled hypertension and diabetes presents with sudden onset of weakness. His blood pressure is 200/115 mm Hg, and his pulse is 80 per minute. An X-ray film of the chest demonstrates cardiomegaly and pulmonary edema. A CT scan of the brain reveals intra-parenchymal hemorrhage. The patient becomes unresponsive and eventually expires. Which of the following was the most likely site for cerebral hemorrhage in this patient? \nSelect and explain. \nA. Basal ganglia/thalamic area, B. Frontal lobe cortex (cortical layers IV through VI), C. Medulla, D. Midbrain', 'role': 'user'}, {'content': 'Answer: A \nExplanation: Cerebral hemorrhage causes stroke (apoplexy). Cerebral hemorrhages that occur without trauma are referred to as "spontaneous," although most are related to preexisting vascular lesions (Charcot-Bouchard aneurysms) or are the consequence of long-standing hypertension. Hypertensive intracerebral hemorrhage occurs at preferential sites, which in order of frequency are the basal ganglia-thalamus (65%), pons (15%), and cerebellum (8%). Necrosis of pyramidal neurons of Sommer\'s sector in the hippocampus (choice E) occurs as a consequence of global anoxia.Diagnosis: Cerebral hemorrhage', 'role': 'assistant'}]
