RESUMO
The Brown-Sequard syndrome involves a hemisection of the spinal cord. Usually occurs as a result of penetrating trauma, with an incidence of 2-4% in traumatic injuries of the spinal cord, being more common in men. We report the case of a male patient, 40 years of age; attended the "University Hospital School," located in the city of Tegucigalpa, Honduras, for referring pain in the interscapular thoracic spine, mild episode that improves with the use of common analgesics. Four days before admission to the emergency area, the pain intensifies, becomes continuous, disabling, no improvement even with use of oral analgesics and even with intravenous medication. Brown Sequard syndrome is not diagnosed by a herniation, the rule states detect spinal trauma, but determining other etiologies have added clinical importance to avoid misdiagnosis.
