摘要
目的探讨足月儿与早产儿局灶性脑白质损伤的常规MRI、DWI影像学特征。方法回顾性分析自2013-11～2014-08间在我院新生儿科经MRI检查诊断为新生儿局灶性脑白质损伤（punctate white matter lesions,PWML）的新生儿,并分析其常规MRI、DWI影像表现及临床特点。结果足月儿有22例发生簇状损伤,早产儿有9例发生簇状损伤,组间比较有显著性差异（P〈0.05）;早产儿有5例发生线状损伤,足月儿则未发生线状损伤,组间比较有显著性差异（P〈0.05）。簇状、线状损伤患儿监测到的胼胝体压部高信号明显多于点状损伤（P〈0.05）。结论局灶性脑白质损伤可见于早产及足月儿,线状损伤以早产儿多见,簇状损伤常见于足月儿;点状损伤病灶分布较广,多位于脑室周围,以侧脑室体后部较常见;簇、线状损伤主要累及脑室周围白质及胼胝体压部。
Objective To investigate the routine MRI and DWI imaging features of PWML in neonates. Methods The routine MRI and DWI images and clinical data of infants with PWML were analyzed retrospectively form Nov. 2013 to Aug. 2014. Results Clustered damage occurred in 22 cases of full- term children,there were clustered damage occurring in 9 preterm children,and there was significant difference（ P〈0. 05） between the two groups; there was linear injury occurring in 5 preterm children,linear damage did not occur in the term children,and there were more significant differences（ P〈0. 05） between the two groups. Tufted and linear damage monitoring corpus callosum had higher signal significantly than punctate injury（ P〈0. 05）. Conclusion Focal PWML in premature and full- term children can be found,linear damage is common in preterm children,and tufted injury is common in full- term children; punctate damage lesions widely distribute,and more in the periventricular to lateral body; cluster and linear damage mainly involve PWML and corpus callosum.
