Patients with symptoms of sacral plexopathy, radiculopathy, or sciatica may have disease originating in the neural elements, sacrum, bony pelvis, pelvic soft tissues, or gluteal region. As illustrated in our companion article, the sacral plexus and surrounding structures can be visualized in detail with MR imaging. This pictorial essay illustrates the MR findings in a number of abnormalities affecting the sacral plexus. Multiplanar MR examination is particularly helpful in defining neural levels of involvement by disease in this region.
出现骶丛神经病变、神经根病或坐骨神经痛症状的患者，其疾病可能源于神经组织、骶骨、骨盆、盆腔软组织或臀区。正如我们的配套文章中所阐述的，骶丛及其周围结构可通过磁共振成像（MR）进行详细可视化。这篇图文并茂的文章展示了影响骶丛的多种异常情况的MR表现。多平面MR检查对于明确该区域疾病累及的神经层面特别有帮助。
