摘要
目的探讨小儿外部性脑积水的CT表现及临床诊断,提高CT对诊断外部性脑积水重要性的认识。方法回顾性分析近年来本院经CT检查确诊为外部性脑积水的29例患儿,10例因伴有脊膜膨出行侧卧位扫描,19例在半坐位2 h后先行仰卧位扫描,完成之后立即俯卧,分别于半小时及1 h后行侧俯卧位及俯卧位扫描。结果 29例均有双侧额顶区蛛网膜下腔增宽,16例伴双侧颞叶蛛网膜下腔增宽,27例半球间隙增宽,18例鞍上池增大,3例侧脑室前角轻度扩大,22例双侧额顶部脑沟增宽增深,19例显示随着体位和时间的改变,外部性脑积水的位置发生明显变化。结论螺旋CT任意多方向容积重建可清晰显示小儿脑组织大体解剖结构,对婴幼儿外部性脑积水有较高的诊断价值。
Objective To explore CT performance and clinical diagnosis of external hydrocephalus in children, so as to improve recognition of importance about CT for diagnosis of external hydrocephalus. Methods 29 cases of children with external hydrocephalus diagnosed by spiral CT were retrospectively analyzed, 10 cases combined with meningocele were examined in lateral position CT scan, the 19 patients were examined in supine position CT scan firstly having been done in the semi-sitting position 2 hours latterly, and then tune turn to prone and prone position CT scan separately in half an hour and one hour latterly. Results 29 cases had subarachnoid space broaden in frontal and parietal lobe of both sides, 16 cases combined with subarachnoid space broaden in temporal lobe of both sides, 27 case combined with longitudinal fissure broaden, 18 cases combined with suprasellar cistern enlarged, 3 cases had anterior horn of lateral ventricle slightly enlarged, 22 cases combined with groove widened and deepened in frontal and parietal lobe of both sides, 19 cases showed the external hydrocephalus locations changed obviously associated with body position. Conclusion Anatomical structure of brain tissue may be shown clearly by spiral CT scan volume reconstructed with multiple angles and multiple position wantonly, which can provide diagnosis accurately in external hydrocephalus of childhood.
