It is formed by the ventral rami of the lumbar and sacral spine which then combine into larger nerves serving the pelvis and lower extremities. It can be a source of severe disability and morbidity for patients when afflicted with pathology. Patients may experience motor weakness, sensory loss, and\/or debilitating pain. Primary neurologic processes can affect the lumbosacral plexus in both genetic and acquired conditions and typically affect the plexus and nerves symmetrically. Additionally, its unique relationship to the pelvic musculature and viscera render it vulnerable to trauma, infection, and malignancy. Such conditions are typically proceeded by a known history of trauma or established pelvic malignancy or infection. Magnetic resonance imaging is an invaluable tool for evaluation of the lumbosacral plexus due to its anatomic detail and sensitivity to pathologic changes. It can identify the cause for disability, indicate prognosis for improvement, and be a tool for delivery of interventions. Knowledge of proper MR protocols and imaging features is key for appropriate and timely diagnosis. Here we discuss the relevant anatomy of the lumbosacral plexus, appropriate imaging techniques for its evaluation, and discuss the variety of pathologies that may afflict it.<\/jats:p>","DOI":"10.1111\/jon.12253","type":"journal-article","created":{"date-parts":[[2015,5,1]],"date-time":"2015-05-01T17:24:56Z","timestamp":1430501096000},"page":"691-703","source":"Crossref","is-referenced-by-count":39,"title":["MR Imaging of the Lumbosacral Plexus: A Review of Techniques and Pathologies"],"prefix":"10.1111","volume":"25","author":[{"given":"Ethan A.","family":"Neufeld","sequence":"first","affiliation":[{"name":"University of California Davis Medical Center Department of Radiology  4860 Y Street Suite 3100 Sacramento CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter Yi","family":"Shen","sequence":"additional","affiliation":[{"name":"University of California Davis Medical Center Department of Radiology  4860 Y Street Suite 3100 Sacramento CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna E.","family":"Nidecker","sequence":"additional","affiliation":[{"name":"University of California Davis Medical Center Department of Radiology  4860 Y Street Suite 3100 Sacramento CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gabriel","family":"Runner","sequence":"additional","affiliation":[{"name":"University of California Davis Medical Center Department of Radiology  4860 Y Street Suite 3100 Sacramento CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cyrus","family":"Bateni","sequence":"additional","affiliation":[{"name":"University of California Davis Medical Center Department of Radiology  4860 Y Street Suite 3100 Sacramento CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gary","family":"Tse","sequence":"additional","affiliation":[{"name":"University of California Davis Medical Center Department of Radiology  4860 Y Street Suite 3100 Sacramento CA 95817"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cynthia","family":"Chin","sequence":"additional","affiliation":[{"name":"University of California San Francisco Medical Center, Department of Radiology  505 Parnassus Avenue, M\u2010391 San Francisco CA 94143\u20100628"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2015,5]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1510\/icvts.2007.151993"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.304095135"},{"key":"e_1_2_14_4_1","first-page":"1011","article-title":"Imaging of the peripheral nervous system: evaluation of peripheral neuropathy and plexopathy","volume":"19","author":"Maravilla KR","year":"1998","journal-title":"AJNR"},{"key":"e_1_2_14_5_1","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1177\/000313481007600303","article-title":"Surgical anatomy of the retroperitoneal spaces, Part IV: retroperitoneal nerves","volume":"76","author":"Mirilas P","year":"2010","journal-title":"Am Surg"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.6.3.2825251"},{"key":"e_1_2_14_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00256-011-1183-6"},{"key":"e_1_2_14_8_1","first-page":"203","article-title":"Obturator neuropathy.
