目的:探讨急性CO中毒患者的头颅CT表现特征及其诊断。材料与方法:22例急性CO中毒患者,其中,男性15例,女性7例,年龄为6～68岁,男女之比为2.14:1,时间为CO中毒后12小时至3年内均进行CT平扫,其中8例进行复查,4例进行增强扫描。结果:急性CO中毒头颅CT表现分为四种类型:1)CT表现正常者;2)单纯苍白球区低密度灶;3)单纯双侧侧脑室旁白质广泛低密度灶;4)脑组织内多发低密度灶。结论:急性CO中毒的患者及时行头颅CT平扫检查对于尽早发现病灶和及时治疗以及估计预后有重要实用价值。
Objective: To investigate craniocerebral CT features and diagnosis in patients with acute CO poisoning. MATERIALS AND METHODS: Twenty-two patients with acute CO poisoning were enrolled. Among them, 15 were male and 7 were female. The age ranged from 6 to 68 years old. The ratio of male to female was 2.14: 1. CT was performed within 12 hours to 3 years after CO poisoning Sweep, of which 8 cases were reviewed, 4 cases were enhanced scan. Results: There were four types of head CT manifestations of acute CO poisoning: 1) normal CT; 2) simple globus pallidus with low density lesions; 3) simple bilateral periventricular white matter mass with low density lesions; 4) Multiple low-density stove. Conclusion: Acute CO poisoning in patients with timely head CT scan for the early detection of lesions and timely treatment and prognosis of important practical value.
