Coexistence of rhombencephalosynapsis and Dandy-Walker malformation has previously been documented in a fetus by autopsy. In addition, there are three cases in the imaging literature suggesting this combination. This paper reports an 8-month-old girl with clear MR imaging evidence of association of these two anomalies. The vermis was absent, and there was fusion of the cerebellar hemispheres, characteristic for rhombencephalosynapsis. The fourth ventricle showed cystic dilatation associated with an enlarged posterior fossa, characteristic for Dandy-Walker malformation. These findings suggest that rhombencephalosynapsis and Dandy-Walker malformation can coexist.
尸检曾证实一名胎儿存在菱脑融合与丹迪-沃克畸形并存的情况。此外，影像学文献中有三例病例提示了这种联合情况。本文报告了一名8个月大的女童，其磁共振成像（MR）有明确证据显示这两种异常并存。小脑蚓部缺如，小脑半球融合，这是菱脑融合的特征。第四脑室呈囊性扩张，伴有后颅窝增大，这是丹迪-沃克畸形的特征。这些发现表明菱脑融合与丹迪-沃克畸形可以并存。
