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 tumour 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.
