RESUMO
OBJECTIVE: To examine the surgical results of unilateral lumbar discectomy in patients with bilateral leg pain and discuss short- and long-term outcomes within the limits of lumbar decompression. METHODS: We analyzed 60 patients with unilateral disc herniation who underwent unilateral lumbar discectomy and hemipartial laminectomy between 2014 and 2017. Group 1 (30 patients) had bilateral leg pain and unilateral lumbar disc herniation. Pain lateralization was determined radiologically. Group 2 (30 patients) had unilateral leg pain and unilateral lumbar disc herniation. Pain scores were preoperatively evaluated with visual analog scale (VAS) for both legs and Oswestry Disability Index (ODI) for overall life quality. In both groups, surgery was performed on the ipsilateral side of the herniated disc. Scores were repeated on postoperative day 1 and 1, 3, 6, 12, and 24 months later. VAS score differences for pain lateralization and disc levels were compared in group 1. ODI score differences were compared between both groups. Results were statistically analyzed. RESULTS: VAS score differences were statistically significant at all follow-up time points in patients with ipsilateral and contralateral pain. VAS score differences between L4-L5 and L5-S1 level discopathies were statistically insignificant for all time points in both groups. All postoperative ODI score decreases for all time points were statistically significant (P < 0.001) for both groups, whereas the differences between groups 1 and 2 were statistically insignificant. CONCLUSIONS: Conventional lumbar disc surgery alone is sufficient for the ipsilateral side of radiologically demonstrated disc herniation in patients with bilateral leg pain.

BACKGROUND: Involvement of spine in patients with hydatid disease (HD) is less than 1% and primary intra-spinal extradural HD is extremely rare. Although this disease is introduced as benign pathology according to its clinical presentation and biological behavior, intraoperative rupture of the cyst may aggravate the patients' outcome in the long-term especially in pediatric patient population. CASE PRESENTATION: We report a 9-year-old girl who presented a progressive neurological deterioration due to an enlargement of a ventrally located extradural hydatid cyst within the thoracic spinal canal. Total removal of the cyst was achieved by preserving the capsule integrity for preventing potential seeding. Our preoperative initial diagnosis based on the radiological findings was confirmed as cyst hydatid histopathologically. CONCLUSION: Cyst hydatid should be considered in the differential diagnosis of the presence of homogenous cystic lesions with regular shape inside the spinal canal especially in patients from endemic region. To our knowledge, this pediatric patient is the first case of cyst hydatid located ventral side of the spinal cord extradurally located inside the spinal canal showing no extension.
