ABSTRACT

Objective To summarize the experiences of the diagnosis and treatment of the intraspinal tumors. Methods One hundredand twenty-three cases of the intraspinal tumors were analyzed retrospectively. Results The intraspinal tumors in those patients included meningiomas/neurofibroma in 32 cases (19.5%), neurinoma in 32 cases (26.0%), ependymoma in 8 cases (6.5%), astrocytoma in 13 cases (10.6%), lipoma in 10 cases (8.1%), metastatic tumors and hemangioma each in 5 cases (4.1%), arachnoid cyst in 9 cases (7.3%), and others in 17 cases (13.8%). The extramedullary subdural, epidural and intramedullary tumors accounted for 56.9%, 21.1% and 22.8%. According to the locations, 30.1% tumors located at cervical region, 37.4% at thoracic region, 19.5% at lumbar region and 13.0% at sacral segments. The total removal rates of tumors were 69.1% (the total removal rates of extramedullary tumors were 70.1%, and the removal rates of intramedullary tumors were 60.7%).The improvement rates of different degree of movement, sense and sphincter function were 75.2%, 73.8% and 77.8%. Conclusion Most of the intraspinal tumors are benign, and the surgical outcome is satisfied. The keys of therapeutic efficacy were MRI and microsurgical techniques application. The spinal stability reconstruction is in the extreme need if spinal stability is breached in surgery.
