A rare case of giant sacral perineurial cyst, causing sciatic pain, explored by myelography and computerized tomography, is reported. The cyst, associated with large erosion of the sacrum, was poorly visualized on the myelography, because of its large size, whereas it was better defined on CT scan. Sacral perineurial cysts are usually small and asymptomatic and rarely cause radicular symptoms. The radiological diagnosis and the treatment of these nerve root cysts are briefly discussed.
报告了一例罕见的巨大骶部神经束膜囊肿，该囊肿导致坐骨神经痛，通过脊髓造影和计算机断层扫描进行了检查。该囊肿伴有骶骨的大面积侵蚀，由于其尺寸较大，在脊髓造影上显示不佳，而在CT扫描上则显示得更清晰。骶部神经束膜囊肿通常较小且无症状，很少引起神经根症状。本文简要讨论了这些神经根囊肿的放射学诊断和治疗。
