摘要
目的探讨MRI在超声发现胎儿侧脑室扩张中的进一步应用价值。方法分析2010年2月-2013年5月期间，35例妊娠25—37周孕妇产前超声检查发现胎儿侧脑室扩张，在3d内行脑部MRI的胎儿为研究对象，出生后12例婴儿行脑部MRI检查。结果在35例中，MRI诊断侧脑室扩张33例，占超声诊断94．3％。10—11．9mm组12例36．4％，颅内未见结构畸形；12—15mm组13例39．4％，合并颅内结构畸形2例；〉15mm组8例24．2％，合并颅内结构畸形4例及侧脑室内出血2例。孤立性侧脑室扩张25例，合并脑水肿6例24％。结论产前超声诊断孤立性侧脑室扩张的胎儿，有必要进一步MRI检查，以帮助排除颅内结构畸形或脑积水。
Objective Exploring the further application value of MRI in fetal lateral ventricle enlargement found by ultrasound. Methods 35 pregnant women were analysed from February 2010 to May 2013,whose fetuses were exarnined with Brain MRI in three days after prenatal ultrasound examination founding fetal lateral ventricle enlargement. 12 fetuses were checked by Brain MRI after birth. Results In 35 cases, MRI diagnosed 33 cases, which accounted for 94.3% of ultrasound dignosis. The group of 10-11.9 mm had 12 cases ,without intraeranial deformity.13 cases between 12-15 ram, with two intracranial deformity. 8 cases were greater than 15 ram, with four intracranial deformity and two lateral ventricle hemorrhage. 25 cases were isolated lateral ventricle enlargement,complicating with six encephaledema. Conclusion It＇s necessary for the fetuses,who diagnosed isolated lateral ventricle enlargement by prenatal ultrasound,to have further MRI examination so that excluding intracranial deformity or hydrocephalus.
