The rostral interstitial nucleus of the medial longitudinal fasciculus (riMLF) and the interstitial nucleus of Cajal (iC) are involved in the generation of vertical and torsional saccades and gaze holding. Midbrain lesions involving either riMLF or iC produce a tonic torsional ocular deviation to the contralesional side. Lesions of the iC are associated with an ipsilesional torsional nystagmus (TN). For the first time, we describe a patient with a unilateral midbrain lesion showing a contralesionally beating torsional nystagmus. This nystagmus was probably caused by a lesion involving the riMLF.
内侧纵束嘴侧间质核（riMLF）和 Cajal 间质核（iC）参与垂直和扭转性扫视以及凝视的维持。累及 riMLF 或 iC 的中脑病变会导致向对侧的强直性扭转性眼偏斜。iC 病变与同侧扭转性眼球震颤（TN）相关。我们首次描述了一名患有单侧中脑病变的患者，其出现对侧跳动性扭转性眼球震颤。这种眼球震颤可能是由累及 riMLF 的病变引起的。
