The features of images and the treatment of sacral nerve root cysts—68 cases report

Objective: To study the clinical and imaginal features of sacral nerve root cysts and try to improve the clinic diagnosis and treatment.Methods: The clinical manifestation and medical imagines of 68 cases with sacral nerve root cysts were analised MRI 35 cases, CT scan 16, myelography 29, and X-ray films 68.Results: Low back pain and sacral nerve symptoms were the main clinical characteristics; MR showed low signals on T₁ weighted images and high signals on T₂ weighted images, similar to CSF. CT scan and X-ray films illustrated sacral vertebral erosions. Myelogram demonstrated contrast layering in the sacral Perineural cysts Decompress and cysts resection were performed fifteen cases. Conclusion: MRI, myelogram are very important in the differential diagnosis of sacral nerve root cysts and may avoid the miss diagnosis due to the limits of CT scans. Surgical operation may be needed if conservative treatment is not avail.
