RESUMO
Results of 63 surgically treated intradural spinal tumors between the period of October 2003 and December 2014 at Bangabandhu Sheikh Mujib Medical University (BSMMU) and in our private settings, Dhaka, were analyzed retrospectively. There were 33 males, 30 females with an average age of 52.4 years (13-70 years) and followed up for at least a year. The preoperative symptom with duration, tumors location and intradural space occupancy and the histopathological diagnosis were analyzed. Pain was evaluated by the visual analogue scale (VAS) and the neurologic function was assessed by Nurick's grade. The tumors were located as, thoracic (n=32, 50.79%), lumbar (n=16, 25.39%), cervical (n=05, 07.93%), and junctional (n=10, 15.87%, CervicoThoracic-01, Thoracolumbar-09). The histopathological diagnosis included schwannoma (n=30, 47.7%), meningiomas (n=14, 22.3%), neurofibroma, arachnoid cyst and myxopapillary ependymoma (n=03, 04.76%) each and paraganglioma (n=01, 01.59%). Among the intramedullary tumors, ependymoma (n=03, 04.76%), astrocytoma and epidermoid cyst (n=02, 03.17%), haemangioblastoma, paraganglioma and cavernous haemangioma (n=01, 01.59%) each. The VAS score was reduced in all cases from 8.0±1.2 to 1.2±0.8 (p<0.003) and the Nurick's grade was improved in all cases from 3.0±1.3 to 1.0±0.0 (p<0.005). The preoperative neurological deficit improved within 8 postoperative weeks in most cases and within 1 postoperative year in all cases. Complications included cerebrospinal fluid leakage, parasthesia and further neurological deterioration (Astrocytoma) (n=02, 03.17%) and dependant bedsore and recurrence (Ependymoma) (n=01, 01.59%). Aggressive surgical excision potentially minimizes neurologic morbidity and improved outcome except intramedullary tumors where initial treatment consists of maximum safe surgical resection or biopsy.
