摘要
目的研究产前超声检查在胎儿胼胝体发育不全（ACC）中的诊断价值。方法回顾性总结10例胎儿ACC的超声表现以及相关的胎儿中枢神经系统（CNS）和神经系统外畸形特点。结果10例ACC病例均有特殊的颅内声像图表现，产前诊断7例完全缺失，3例部分发育不全，其中ACC合并CNS外畸形6例，合并CNS内其他畸形8例，同时合并CNS内、外畸形5例。结论超声产前诊断ACC具有重要的临床价值，应重视颅内一系列间接征象并熟悉常见伴发畸形，以提高检出率。
Objective To assess the value of prenatal sonographic diagnosis on fetal agenesis of corpus callosum（ACC）. Methods A retrospective study was on prenatal sonographic findings of 10 cases with ACC malformation and their abnormalities in central nervous system （CNS） or extra-CNS. Results The special sonographic findings established the diagnosis of ACC malformation in all 10 cases, with 7cases diagnosed absence agenesis. Among all patients with ACC,6 cases were accompanied with abnormalities in extra-CNS,8 in CNS and 5 in both. Conclusions Prenatal ultrasonography plays a vital role in accurate diagnosis on fetal ACC. Attentions should be paid to the indirect encephalic features and complicated abnormalities so as to make accurate and prompt diagnosis.
