Giant "invasive" schwannomas of the spine occur occasionally, most frequently in the lumbar region. We present the case of a 46-year-old woman with giant "invasive" schwannoma of the lumbar spine, with a 12-year history of illness. The tu-mour originated in the vertebral canal and passed through the paraspinal muscles and retroperitoneal area to the abdominal cavity. The part of the tumour which was in the abdominal cavity was removed by means of laparotomy during the first operation. In the second one, the remaining part of the tumour was removed completely from the vertebral canal and retroperitoneal area through posterior-lateral access. The spine was stabilized with metal implants. Histological examination revealed cellular schwannoma. During the follow-up the pain resolved while paresis of the right quadriceps muscle of the thigh was still present. Cellular schwannoma is a benign form of schwannoma, but it may cause a local recurrence if not removed completely.
脊柱巨大“侵袭性”神经鞘瘤偶有发生，最常发生于腰椎。我们报告 1 例 46 岁女性患者，12 年前出现腰椎巨大“侵袭性”神经鞘瘤，肿瘤起源于椎管，穿过椎旁肌肉和腹膜后区进入腹腔。第一次手术采用剖腹术切除了腹腔内的肿瘤部分。第二次手术通过后路外侧入路从椎管和腹膜后区完全切除了剩余的肿瘤部分。脊柱用金属植入物固定。组织学检查显示为细胞性 schwannoma。随访时，疼痛缓解，但大腿股四头肌的瘫痪仍然存在。细胞性 schwannoma 是 schwannoma 的良性形式，但如果不能完全切除，可能会局部复发。
