title: MR imaging of the sacral plexus: abnormal findings.
abstract: 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.
