We report prenatal and neonatal neuroimaging findings in a case of oral-facial-digital syndrome type VI (OFDS VI). Prenatal MR imaging at 29 weeks' gestation showed hypoplastic cerebellar vermis and hemispheres, the molar tooth sign, and a hypothalamic hamartoma. Neonatal MR imaging confirmed these findings. The neonate developed breathing abnormalities and exhibited frontal bossing, multiple bucco-alveolar frenula, and postaxial hexadactyly of both hands. If the molar tooth sign and a hypothalamic hamartoma are present, prenatal diagnosis of OFDS VI is possible.
我们报告了一例Ⅵ型口面指综合征(OFDS VI)的产前和新生儿神经影像学检查结果。妊娠29周时的产前磁共振成像显示小脑蚓部和半球发育不全、磨牙征以及下丘脑错构瘤。新生儿磁共振成像证实了这些发现。该新生儿出现呼吸异常,并表现出前额突出、多个颊牙槽系带以及双手轴后多指畸形。如果存在磨牙征和下丘脑错构瘤,则有可能在产前诊断OFDS VI。
