脑先天性感染的CT诊断价值探讨(附6例分析)

Significance of CT in the diagnosis of congenital brain infection(analysis of 6 cases)

目的探讨先天性脑感染(TORCH)的CT表现及诊断价值。方法分析6例经母子两代血清学检查证实的先天性TORCH感染新生儿、婴幼儿脑CT表现。其中先天性脑弓形虫病3例,先天性脑弓形虫巨细胞病毒联合感染1例,先天性风疹病毒感染1例,先天性巨细胞病毒感染1例。结果脑发育不良,脑室扩张,室管膜下区及脑白质钙化斑等是先天性脑TORCH感染的一组CT表现。结论婴幼儿期不明原因的脑内钙化应注意脑先天性感染的可能,血清学检查具有诊断意义。

Objective To investigate the brain CT manifestations in congenital TORCH infection.Methods Analysis of 6 cases of congenital TORCH infection of the neonates and infants demonstrated by serum examination was performed.There were congenital toxoplasmosis 3 cases,congenital toxoplasmosis and cytomegalo-virus infection 1 case,congenital rubella virus infection 1 case,congenital cytomegalovirus infection 1 cases.Results Cerebral hypoplasia,ventricular dilatation,subependymal and parenchymal calcifications,et al,were demonstrated by CT with congenital TORCH infection.Conclusion Typical brain CT manifestations together with clinical signs may suggest congenital TORCH infection,Brain calcifications of unknown cause in infant is suggestive of congenital TORCH infection,while serological test can be diagnostic.
