Abstract
Background: Meningioma is a common tumor that ac-counts for 25-46% of spinal neoplasms. It is generally benign, and slow growing. Spinal meningiomas occur after the fourth decade of life Mostly, they are located in the intradural compartment, generally respecting the pial layer of the spinal cord. The most frequent site of spinal meningiomasis in the thoracic region Clinical findings variate from mild to significant neurologic dysfunction; the most frequent clinical findings are back pain,sensori-motor deficit and sphincter dysfunction. The goal of surgical treatment must be total resection, if possible and usually not difficult.
Objective: This study was made to present the incidence, clinical presentation, localization, techniques, used in the management of spinal meningioma. And to evaluate the func-tional outcome of surgically treated cases.
Patients and Methods: This is a retrospective study of Sixteen patients with spinal meningiomas who had undergone microsurgical resection were treated between 2012 and 2015 in our department. Clinical presentation, diagnosis, histological examination, microsurgical resection, functional outcome were evaluated, defining potential prognosis factors associated with these lesions.
Results: Tumors site was intradural,extramedullary the most common site was the thoracic region, posterolateral and antero-lateral. Surgical resection was complete in 14 patients (87.5%) and incomplete in 2 patients (12.5%) At the last follow-up the neurological state was improved or unchanged in 15 patients (93.75%) and worse in one patients (6.25%).
Conclusion: Magnetic resonance imaging is the best imaging technique for diagnosis. Total tumor resection im-proved the surgical results of spinal meningiomas.
