目的探讨小儿外伤性脑梗塞的CT诊断价值及表现特征。方法回顾性分析30例小儿外伤性脑梗塞的临床表现和CT资料。结果基底节区梗塞25例(83.3%),呈圆形或椭圆形小片状低密度影,边缘清楚或模糊,其中24例伴基底节区钙化,脑叶梗塞5例(17.7%),呈大片扇形低密度影,边界清楚。结论CT检查对外伤性脑梗塞的诊断有重要价值,动态观察不仅可以发现迟发性梗塞灶,而且可以观察其变化过程。
Objective To investigate the diagnostic value and characteristics of CT in pediatric traumatic cerebral infarction. Methods Retrospective analysis of 30 cases of pediatric traumatic cerebral infarction clinical manifestations and CT data. Results The basal ganglia infarction was found in 25 cases (83.3%) with circular or oval platelet - shaped low density with clear or fuzzy margins. There were 24 cases with basal ganglia calcification and cerebral infarction in 5 cases (17.7%). Large fan-shaped low-density shadow, clear boundary. Conclusion CT examination has important value in the diagnosis of traumatic cerebral infarction. Dynamic observation can not only find the delayed infarction, but also observe the change process.
