MR imaging depicted vertically oriented folia instead of the normal horizontal folial pattern, hypoplastic cerebellar vermis, fusion of the inferior posterior cerebellum, and probable polymicrogyria in the superior cerebellar hemispheres in a child with hypotonia, nystagmus, ataxia, and psychomotor retardation. We propose that this newly discovered cerebellar malformation be added to the list of malformations associated with aplasia or hypoplasia of the cerebellar vermis, such as Dandy-Walker malformation, Joubert syndrome, tectocerebellar dysraphia, and rhombencephalosynapsis.
磁共振成像显示，一名患有肌张力减退、眼球震颤、共济失调和精神运动发育迟缓的儿童，其小脑叶呈垂直方向排列，而非正常的水平叶状模式，小脑蚓部发育不全，小脑后下部融合，小脑上半球可能存在多小脑回。我们建议将这种新发现的小脑畸形添加到与小脑蚓部发育不全或发育不良相关的畸形列表中，如丹迪-沃克畸形、儒贝尔综合征、顶盖小脑发育不全和菱形脑联合畸形。
