Abstract：
BACKGROUND: Posterior mediastinal leiomyosarcoma is an extremely rare malignant mesenchymal tumor with no special clinical symptoms, which is easily confused with some common tumors in the posterior mediastinum, affecting the accuracy of the first diagnosis by clinicians and delaying the treatment of patients.
METHODS: We report a 59-year-old woman with a space-occupying lesion in the posterior mediastinum. The patient was mistakenly diagnosed with lumbar muscle or vertebral body lesions due to chest and back pain and underwent conservative treatment, but her symptoms did not improve significantly and she gradually developed pain in both lower limbs. Chest computed tomography (CT) scan indicated the left lower lung paraspinal space and underwent standard single-aperture video-assisted thoracoscopic surgery (VATS), which was pathologically confirmed as posterior mediastinal leiomyosarcoma.
CONCLUSIONS: Complete surgical resection of posterior mediastinal leiomyosarcoma can achieve good clinical results.

摘要：
背景：后纵隔平滑肌肉瘤是一种极其罕见的恶性间质瘤，无特殊临床症状，很容易与后纵隔的一些常见肿瘤混淆，影响临床医生首次诊断的准确性，延误患者的治疗。
方法：我们报告了一名59岁女性，后纵隔占位病变。患者因胸背部疼痛误诊为腰肌及椎体病变，行保守治疗，但是她的症状没有明显改善，并且逐渐出现双下肢疼痛。胸部计算机断层扫描（CT）扫描显示左下肺椎旁间隙，并接受了标准的单孔径电视胸腔镜手术（VATS），经病理证实为后纵隔平滑肌肉瘤。
结论：完全手术切除后纵隔平滑肌肉瘤可取得良好的临床效果。
