闭唇型脑裂畸形的MR诊断

摘要

目的:探讨闭唇型脑裂畸形的MR诊断价值.方法:回顾性分析15例闭唇型脑裂畸形的MR表现.结果:15例闭唇型脑裂畸形中13例为双侧脑裂畸形,位于额叶11例,顶叶2例.2例为单侧脑裂畸形,分别位于额叶、顶叶区域.T1WI呈条状低信号影,T2 WI呈条状高信号裂隙,裂隙边缘见脑回状灰质信号,增强扫描脑实质内未见异常强化灶.11例侧脑室轻度扩大,裂隙连接侧脑室体部,体部边缘见三角形及尖角状突出,2例侧脑室边缘见团块状突起.结论:闭唇型脑裂畸形的MR表现具有特征性,MR在闭唇型脑裂畸形诊断中具有重要价值.%Objective:To investigate the value of MR in the diagnosis of schizencephaly. Methods: MR manifestations of 15 patients with schizencephaly were analyzed retrospectively. Results:The plain CT manifestations of foreign body in the esophagus were appeared as high density shadows in short or long strip · The thickening of the esophageal wall was shown in 6 cases, foreign body was penetrated outside of the esophageal wall in 5 cases, air around esophagus and in mediastinum, extensive air in mediastinum, and left lower lobe atelectasis in one case. Conclusion: MR manifestations of schizencephaly has some features, and MR has an important value in the diagnosis of schizencephaly.
