婴幼儿惊厥与额叶脑回发育迟缓的CT观察随访

CT follow-up for infantile contusions and frontal lobe gyrus stunt

目的讨论婴幼儿早期惊厥与额叶脑回发育落后的关系及CT表现。方法对临床150例惊厥患儿出院后随访,选择有完整追踪资料的69例经头颅CT检查诊断为额叶脑回发育迟缓患儿,定期评价至3岁龄。结果额叶发育迟缓及惊厥发作人次均以6、9个月两个年龄段最多,1～、2～和3～岁3个年龄段随着脑回的发育,惊厥随之减少。所有病例头围与正常同龄儿比较均在正常低限;各种病因导致的脑额叶发育迟缓的恢复时间有区别,低体重儿恢复快,而肠道感染合并中毒性脑病恢复较慢。结论CT可早期直观提示婴儿、幼儿早期额叶脑回发育迟缓情况,为临床早期确诊婴幼儿良性惊厥提供新的诊断信息。

Objective To discuss the CT features of infantile convusions and frontal lobe gyrus stunt. Methods There 150 convusion infants were followed up after they left hospital,in which 69 cases with complete data were selected for the study. Results The number of convusion and frontal parietal lobe stunt infants was mainly concentrated in the age group of 6 - 9 months. With the growing of gyrus, the incidence of person-times of convusions decreased in the age group of 1 - 3 years. The head circumferences of all cases were at the lower level than normal children of the same age. The convalescences of frontal lobe stunt led by diversified pathogeny were different. Low body weight infants recovered more quickly than those with intestinal-infection and poisoned encephalopathy. Conclusion CT scanning can discover the frontal lobe gyrus stunt at early stage of infants and provide accurate information for clinical diagnosis.
