PRIMARY LIPOSARCOMA OF THE LUMBAR SPINE: CASE REPORT.

We report a rare case of primary bone liposarcoma of the lumbar spine, for which only one case has been reported. A female patient, 60 years of age, with lumbar pain and left sciatalgy for six months. In the imaging exams, a destructive tumor was found in the L4 vertebral body, and magnetic resonance imaging (MRI) revealed a tumoral lesion with T1 hiposignal and T2 hypersignal. Histological diagnosis was difficult, and immunohistochemistry confirmed the diagnosis. Surgical treatment was performed with wide ressection, spinal cord decompression, and anterior and posterior fusion of L3 to L5 complemented by radiotherapy and chemotherapy. After three years, a computed tomography (CT) scan evidenced an expansive injury in the lung. Despite its rarity, liposarcoma should be considered in the differential diagnosis of sciatica and primary tumors of the spine.

[Effectiveness of methylprednisolone in the acute phase of spinal cord injuries--a systematic review of randomized controlled trials]. / Efetividade da metilprednisolona na fase aguda do trauma raquimedular--revisão sistemática dos ensaios clínicos randomizados.

UNLABELLED: Steroid therapy has been tested as a protector in spinal cord injury. Multicenter studies evaluating the methylprednisolone (MP) in post traumatic neurological recovery have shown promising results according to NASCIS. A large number of critical studies related to the NASCIS results have been published. OBJECTIVE: To review literature related to use of methylprednisolone compared with placebo. METHODS: This analysis added the average improvement achieved in groups of patients who used MP and placebo (PL) to the average scores of groups at baseline, before treatment, resulting in the final neurological outcome for both groups. RESULTS: The motor score of the MP group was only 2.5 points higher than the PL in a one year follow-up. In neurologically intact patients, the total score is 70 points. Improvement in sensitive scores was also discrete (1.1 and 1.7 points for the pinprick and light touch respectively). A high rate of complications was observed in a group of patients about 60 years old who used MP. CONCLUSION: Differences in the clinical magnitude of benefit obtained (not confirmed by other studies) with the use of MP or PL are not significant, in comparison with the potential for complications when using methylprednisolone.
