摘　　要：目的探讨Joubert综合征的CT和MRI表现。方法回顾性分析10例Joubert综合征患儿临床、CT和MRI资料,10例均行CT平扫,其中4例同时行MR平扫。结果Joubert综合征的典型影像学表现包括小脑半球间“中线裂”、“蝙蝠翼”状和“三角形”第4脑室,以及中脑水平的“磨牙征”。10例行CT检查者,均可见“中线裂”;其中9例显示“蝙蝠翼”状和“三角形”第4脑室,8例显示“磨牙征”。4例行MR检查者均显示上述征象。结论Joubert综合征的CT和MRI表现具有特征性,结合临床可提供明确诊断。Objective To study imaging features of Joubert syndrome on CT and MRI. Methods Ten cases with clinically diagnosed Joubert syndrome were retrospectively studied. Routine CT examinations were performed in all ten cases and MRI in four cases. Results He typical imaging features of Joubert syndrome included “midline cleft” between cerebellar hemispheres, “bat-wing” and “triangular-shaped” fourth ventricle, and “molar tooth sign”. On CT images, all cases had “midline cleft”, “bat-wing” and “triangular-shaped” fourth ventricle was present in nine cases, and “molar tooth sign” in eight cases, On MRI, “midline cleft”, “bat-wing” and “triangular-shaped” fourth ventricle , and “molar tooth sign” were present in all four cases. Conclusion There are typical imaging features of Joubert syndrome, CT and MRI play an important role for the diagnosis.
