Abstract
Background: The lumbosacral plexus consists of the ventral rami from the L2 to S3 nerve roots, with some additions from the L1 and S4 nerve roots as well. The standard treatment for spinal cord compression is urgent surgically decompressive laminectomy over the affected level with resection as much as possible of the exposed tumor to relieve the cord compression. We aim to correlate the impact of preoperative clinical picture, duration of symptoms, and the pathological nature of the lumbo-sacral spine tumors on the outcome of comparative study different modalities of management. Patients and Methods: During the period between 2015 and 2017, thirty cases were studied and surgically managed in Al-Azhar University Hospital, Damietta. Cases were selected for surgery if they were diagnosed as having a symptomatizing lumbosacral lesion. Results: Thirty patients were included in the current study; the commonest lesion in this study was ependymoma eight patients (27%), astrocytoma six patients (20%), and meningioma five patients (17%). Nerve sheath tumor comprised five cases (17%) with the hemangioblastomas three cases (10%), epidermoid one case (3%), and ependymoma of the filum terminale two cases (6%). The mean age of the included patients was 38.96 ± 15.42. The mean duration of lesions was 13.66 ± 10.93. They were 15 male patients (50%), and 15 female patients (50%), with male: female ratio 1:1. The mean duration of symptoms ranged for 1:60 months. The most common presenting manifestations were sensory followed by motor and sphinctric disturbance. Complications occurred in 8 patients (23%), and the most common was postoperative CSF leak. 19 out of 30 cases were surgically totally resected (63%), while 11 cases (37%) were grossly totally resected. Conclusions: Ependymoma and meningioma have more favorable outcome compared to other spinal tumors. Accurate and rapid diagnosis prior to surgery also associated with good outcome.

Summary
The lumbosacral plexus consists of the ventral rami from the L2 to S3 nerve roots, with some additions from the L1 and S4 nerve roots as well [1] It contains around 200000 axons and gives rise to six sensory nerves to the thigh and leg and six major sensorimotor nerves innervating about 43 muscles [2].
