ABSTRACT

Spinal meningiomas are a rare pathology in the pediatric population, its incidence in different series ranges from 1 to 5%, being its most frequent location the thoracic spine, this tumor is associated with genetic diseases as well as sporadic genetic alterations, its intradural extramedullary appearance is the most frequent but not the only one. Extramedullary intradural tumors present with symptoms of spinal cord compression, ranging from referred pain to a spinal cord syndrome depending on the level and degree of involvement. MRI is the study of choice to determine the location and extent of these lesions. Treatment by laminectomy and resection is the usual procedure for occupational lesions found posterior to the spinal canal. We present the case of a 15-year-old male patient with thoracic spinal meningioma presenting dorsal pain and alteration in the posterior cords manifesting gait disturbance. Magnetic resonance imaging showed a lesion that enhanced on contrast medium application at T2-T3 level and was classified as an extramedullary intradural lesion. A posterior approach was performed on the T2-T3 levels, laminectomy of T2-T3 and total microsurgical resection of the lesion. The histology report was conclusive for grade 1 meningioma. The gait disturbance improved in the immediate postoperative period and his neurological function was complete at follow-up. In this report, the authors report a case of spinal meningioma and provide a comprehensive review of the literature on this disease.
