A rare case of giant invasive intraosseous schwannoma in lumbar vertebra with no neurologic deficit is reported. This tumor had vertebral body, left paravertebral tissue and lamina invasion and thus classified as type V giant invasive schwannoma according to Sridhar's classification of benign nerve sheath tumor. Because intraosseous portion was significantly larger than extraosseous portion, this tumor was mentioned as intraosseous schwannoma. Tumor was successfully resected using corpectomy, mesh cage insertion and posterior fixation. Pathological diagnosis was benign schwannoma.
