ABSTRACT
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.

The discovery of the pyramidal syndrome and tract is briefly reviewed with emphasis on a few key historical aspects. The pursuit of the relationship between the lateralized deficits resulting from contralateral head trauma begins in the fourth century BC with the Hippocratic School and continues until the present day.
Os autores fazem uma breve nota histórica da síndrome piramidal e do feixe piramidal no homem. Os achados de deficiências motoras decorrentes de traumatismo craniano começam a partir do século IV AC com o pai da medicina Hipócrates (460-377) e vão até os dias atuais.

Cruciate paralysis, an unusual clinical entity, is "frequently undiagnosed or misunderstood", and can simulate the acute cervical central-cord injury syndrome. This rare injury pattern is characterized by weakness of upper extremities with little or no compromise of lower limb function following trauma to the superior cervical cord. The pattern of injury and clinical findings support selective damage to the corticospinal tract or upper motor neurons subserving upper limb function with the pyramidal decussation. Authors experience a case of curciate paralysis due to type 2 odontoid fracture and atlas dislocation.
