ABSTRACT: Intramedullary tumors are rare among primary tumors of the central nervous system. They most often affect young adults, with no gender predominance. Spinal schwannomas account for approximately 30% of all spinal tumors. The most common location is in the thoracic region, and they are most often intradural. The patient was a 16-year-old adolescent with no known medical or surgical history, who was admitted for lumbodorsalgia. Examination revealed paraplegia and sphincter disorders. MRI of the thoracolumbar spine revealed an intramedullary tumor extending from D1 to D5. The patient underwent tumor resection followed by functional motor and sphincter rehabilitation, with an unfavorable clinical outcome apart from a slight recovery of sensitivity. Immunohistochemical analysis of the surgical specimen confirmed the diagnosis of schwannoma. The discovery of an intramedullary schwannoma is not unusual. The diagnosis was confirmed by histology, and treatment was surgical.
