摘要
目的:研究新生儿蛛网膜下腔出血的CT表现,提示新征象。材料和方法:对110例新生儿蛛网膜下腔出血(SAH)的CT平扫资料,分析不同的出血和积血部位形成的不同CT图像特征。并与60例成人SAH的CT表现加以对照。结果:发现三个特殊CT征象:(1)矢状窦旁征(Δ征)87例(79.0%)-血液积聚于矢状窦及窦汇旁。(2)天幕缘征(Y征)55例(50.0%)-血液积聚于小脑天幕缘上下。(3)边缘模糊征91例(82.7%)-血液积聚于纵裂池内,深入至大脑半球内侧面脑沟内。结论:蛛网膜下腔出血由于出血部位不同可形成不同的CT表现。作者提出三个新征象:矢状窦旁征,天幕缘征,边缘模糊征。对新生儿蛛网膜下腔出血的诊断有重要价值。
Purpose: A study of CT manifestation of SAH(Subarachoid Space Hemorrhage) in new born was undertaken with new signs suggested. Materials and Methods: The plain CT scans of 110 cases of SAH in new born were analysed resulting in different CT image charateristic due to various kinds and positions of the hemorrhage. Furthermore a comparision with those of the 60 adult SAH cases was also included. Results: The discovery of 3 specific CT findings. (1) parasagittal sinus sign (△Sign) 87 cases (79.0%)-blood accumulated in sagittal sinus and parasinusoid space. (2) tenting border sign (Y Sign), 55 cases (50.0%)-blood accumulated along the superier and inferior parts of the cerebellar tenting border. (3) border blurring sign, 91 cases (80.7%)-blood accumulation within the longitudinal fissure cietern deepering into the internal sulci of the cerebral hemispheres.Conclusion: There were different kinds of CT manifestations of SAH according to the sites of the hemorrhages. The authors presented 3 new specific signs. parasagittal sinus sign, tenting border sign and border blurring sign. All of them posscessed the important value in diagnosing SAH of the new born.
