However, a rare form of HCED, ocular ipsipulsion, is caused by a lateral medullary lesion. The presumed mechanism involves disruption of decussating olivocerebellar fibers, leading to an imbalance in vestibular nuclei activity.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Purpose:<\/jats:bold>\n                    To report a case of isolated ocular ipsipulsion as a diagnostic clue to central vertigo.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Research Design:<\/jats:bold>\n                    Case report.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Study Sample:<\/jats:bold>\n                    An 82-year-old man with a right lateral medullary infarction.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Data Collection:<\/jats:bold>\n                    Neurological examination and brain magnetic resonance imaging (MRI) were performed.
