The authors present a case of a 42-year-old female admitted for disabling complex and atypical bilateral facial spasms associated with painful masticatory and motor ocular dystonic movements, difficult to fit in the definition of any known cranio-facial dyskinesias. MRI showed a left PICA loop invaginated into the brainstem, considered responsible of an hyperactive disorder of the brainstem nuclei neighboring the conflict. After microvascular decompression, the patient made a full recovery with complete disappearance of the paroxystic phenomena. Such a type of image should be searched for, in an intra-axial brainstem location, in the absence of conflict in the cistern at root entry/exit zone (REZ).
作者报告了一例42岁女性患者，因严重的复杂性非典型双侧面部痉挛入院，伴有疼痛性咀嚼和动眼性肌张力障碍运动，难以纳入任何已知颅面运动障碍的定义范畴。磁共振成像（MRI）显示左侧小脑后下动脉襻陷入脑干，被认为是导致邻近冲突部位的脑干核团功能亢进紊乱的原因。微血管减压术后，患者完全康复，阵发性症状完全消失。在脑池神经根出入区（REZ）无冲突的情况下，对于轴内脑干部位，应查找这种类型的影像表现。
