  • Hemiplegia cruciata (HC) manifests as paralysis of the ipsilateral arm and contralateral leg. Herein, we report a 64-year-old man with weakness of the right leg and of the left arm after multiple sclerosis (MS). His brain and spine magnetic resonance imaging show a lower medulla lesion, which is extended to posterior part of C1 spine through cervicomedullary junction. HC usually results from stroke or trauma, but it is rare as presenting symptom of MS.
