摘要
目的 :探讨胼胝体发育不全的MRI特征性表现。材料和方法 :回顾性分析 14例胼胝体发育不全的MRI表现 ,并从组织胚胎学、形态学及病理的角度加以分析解释。结果 :本组胼胝体发育不全分为 3型 :完全缺如 2例 ,其中 1例可见双侧Probst束 ;部分缺如 10例 ;胼胝体完整性存在的但呈整体性或部分性变小 2例。 7例伴有其他先天性脑部畸形 ,包括脂肪瘤、灰质异位、脑裂畸形、多小脑回以及透明隔缺如等。结论 :MRI是诊断胼胝体发育不全及其合并的其他脑部畸形最理想的诊断手段。
Purpose: To investigate the MRI features of dysplasia of corpus callosum. Materials and Methods: MRI findings of 14 cases with dysplasia of corpus callosum were retrospectively analyzed and discussed based on the embryological, morphological and pathological changes. Results: Three types of corpus callosal dysgenesis were recognized: total defect (n=2, bilateral Probst's bundles were identified in one case). partial defect (n=10); intact corpus callosum with total or partial hypoplasia (n=2). The associated congenital anomalies were also observed in 7 of 14 cases, including lipoma, gray matter heterotopia, schizencephaly, polymicrogyria, and deficient septum pellucidum. Conclusion: MR imaging is an ideal method of choice for diagnosing the dysplasia of corpus callosum and other associated congenital cerebral anomalies.
