Chronic perineal pain is an often encountered problem that is difficult to evaluate. Based on a series of 17 patients in whom urological, gynecological, and anorectal pathology was excluded, the authors compared magnetic resonance imaging (MRI) with computed tomographic (CT) scan with myelography in the investigation of chronic perineal pain. After a clinical neurological examination, patients underwent radiodiagnostic imaging of both techniques. Thirteen patients (76%) had one or more sacral meningeal cysts (MC) on MRI scan, whereas CT scan with myelography of the lumbar and sacral region revealed 7 patients (41%) with sacral MC. Sacral MC may be the etiology of chronic perineal pain in many instances, and MRI scan appears to be superior to CT scan with myelography in demonstrating sacral MC. Ten patients with sacral MC were operated on with moderate to excellent results 6 months after operation. Early postoperative results are encouraging, but further follow-up and larger series are required.
慢性会阴部疼痛是一个常见但难以评估的问题。基于一系列17例排除了泌尿外科、妇科和肛肠病理问题的患者，作者在慢性会阴部疼痛的研究中，将磁共振成像（MRI）与计算机断层扫描（CT）脊髓造影进行了比较。经过临床神经学检查后，患者接受了这两种技术的放射诊断成像。MRI扫描显示13例患者（76%）有一个或多个骶部脑脊膜囊肿（MC），而腰骶部CT脊髓造影显示7例患者（41%）有骶部MC。在许多情况下，骶部MC可能是慢性会阴部疼痛的病因，并且在显示骶部MC方面，MRI扫描似乎优于CT脊髓造影。10例有骶部MC的患者接受了手术，术后6个月效果为中度至良好。术后早期结果令人鼓舞，但需要进一步随访和更大规模的系列研究。
