目的探讨成人脊髓栓系综合征(ATCS)的磁共振诊断价值。方法回顾性分析32例经手术、病理证实的ATCS患者的磁共振影像资料。结果 32例ATCS患者,男性19例,女性13例;年龄19～47岁,平均年龄41.2岁。腰骶部、臀部或会阴区不同程度的疼痛为典型临床症状,同时伴有神经功能障碍。磁共振显示脊髓圆锥低位22例,终丝增粗17例;存在脊髓纵裂4例,椎管内脂肪瘤14例,皮样囊肿7例,脊髓脊膜膨出2例和脂肪脊髓脊膜膨出1例。全部病例均显示椎管和终池扩大,长T1长T2信号脑脊液聚集。结论磁共振成像是诊断ATCS的有效方法,可为外科手术提供充分的参考依据。
Objective To investigate the diagnostic value of magnetic resonance imaging in adult tethered cord syndrome (ATCS). Methods The MRI data of 32 patients with ATCS confirmed by surgery and pathology were retrospectively analyzed. Results 32 cases of ATCS patients, 19 males and 13 females; aged 19 to 47 years, mean age 41.2 years. Lumbosacral, buttocks or perineal area of varying degrees of pain as a typical clinical symptoms, accompanied by neurological dysfunction. Magnetic resonance imaging showed low conus spinal cord in 22 cases, terminal filament thickening in 17 cases; presence of spinal cord in 4 cases, 14 cases of intra-oral lipoma, dermoid cysts in 7 cases, 2 cases of spinal meningitis and spinal dural meningitis In 1 case. All cases showed an enlargement of the spinal canal and the terminal pool, accumulation of long T1 long T2 signals in CSF. Conclusion Magnetic resonance imaging is an effective method for the diagnosis of ATCS. It can provide sufficient reference for surgery.
