  History:Patient is a 55-year-old female with history of alcoholism found unresponsive with pulseless electrical activity(PEA). 病史：患者女，55岁，饮酒史，无脉电活动（PEA） Findings :Hypodensity in the deep nuclei of the basal ganglia suggestive of edema.Loss of gray white matter differentiation. 影像表现：基底节深部低密度区，提示水肿。灰白质交界不清。 Diagnosis : Anoxic brain injury 诊断：缺氧性脑损伤。 Discussion: Bilateral symmetrical hypodense lesions of the basal ganglia in adults are compatible with a profound hypoxia, metabolic insult or exposure to toxins. This is presumably since the more metabolically active areas in the brain are preferentially injured. These include the basal ganglia, thalamus, hippocampus, cerebellar hemispheres, brainstem nuclei, and cerebral gray matter. 讨论：成人基底节区双侧对称性低密度病变，较符合脑缺氧史、代谢障碍史或毒物暴露史。这可能是因为大脑较为活跃的新陈代谢区域更容易受伤。包括基底节、丘脑、海马、小脑半球、脑干和脑灰质。 Notes: 1. nuclei [ˈnukliˌaɪ, ˈnju-] n. 核，核心 2. basal ganglia [ˈbesəl ˈɡæŋɡliə] 基底节 3. anoxic [æ'nɒksɪk] adj.缺氧的 4. hypoxia [haɪˈpɑ:ksiə] n. 组织缺氧 5. metabolic [ˌmetə'bɒlɪk] adj.新陈代谢的; 变化的 6. thalamus ['θæləməs] n. 丘脑，室 7. hippocampus [ˌhɪpə'kæmpəs] n. 海马回 8. cerebellar [serə'belə] adj. 小脑的 来源：每天朗读一段医学影像学英语文章 圈主 深圳市人民医院放射科副主任医师杨敏洁 |
