The involved structures within the DLP were the ICP in four patients and the VN in the remaining 14. The unilateral ICP lesions were associated with consistent abnormalities in vestibular and ocular motor tests, including ipsilesional nystagmus without gaze\u2010evoked nystagmus (GEN), and normal head impulse tests (HITs) and caloric response. In contrast, lesions of the VN were associated with a broader range of eye\u2010movement abnormalities, including ipsi\u2010 or contralesional nystagmus with GEN, positive HITs, normal or abnormal caloric responses, and fixation nystagmus. Initial diffusion\u2010weighted magnetic resonance imaging (within 48\u2009h) was falsely negative in 41% (<jats:italic>n<\/jats:italic>\u2009=\u20097) of the DLP infarction cases.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This study demonstrates that unilateral DLP lesions frequently present with isolated AVS and diverse ocular motor abnormalities.
