PURPOSE
To determine whether meningocele manqué can be detected by neuroimaging techniques in dysraphic patients.
METHODS
We reviewed the records and imaging studies of 16 patients with surgically proved meningocele manqué seen at our institution between 1989 and 1990. Both CT and MR imaging techniques were used. CT of the spine was performed immediately following contrast myelography.
RESULTS
Nine of 16 patients (CT, four; and MR, five) showed evidence of meningocele manqué which corresponded to intraoperative findings. Fourteen of 16 patients were found to have diastematomyelia, eight with medium septum and six without a septum. Associated findings included syrinx (six), lipoma (five), dermoid cyst (one), and neuroenteric cyst (one). After completing this review, we were able to prospectively diagnose dorsal bands in two new patients; these bands were confirmed at surgery.
CONCLUSION
Dorsal bands can be detected in dysraphic patients with CT or MR using operative findings as a road map.
目的
确定在脊柱裂患者中，神经影像学技术能否检测出隐性脊膜膨出。
方法
我们回顾了1989年至1990年间在我院接受手术证实为隐性脊膜膨出的16例患者的病历和影像学检查。同时使用了CT和MR成像技术。在脊髓造影后立即进行脊柱CT检查。
结果
16例患者中有9例（CT检查发现4例，MR检查发现5例）显示有隐性脊膜膨出的证据，与术中发现相符。16例患者中有14例发现有脊髓纵裂，其中8例有中等间隔，6例无间隔。相关发现包括脊髓空洞症（6例）、脂肪瘤（5例）、皮样囊肿（1例）和神经肠囊肿（1例）。完成本回顾性研究后，我们能够前瞻性地诊断出2例新患者的背侧束带；这些束带在手术中得到证实。
结论
以手术结果为路线图，使用CT或MR可在脊柱裂患者中检测出背侧束带。
