The patient had previously tried different modalities of treatments, including massage, acupuncture, ultrasound, alternative Bowen therapy and nonsteroidal anti-inflammatory drugs (NSAIDs), all of which only provided temporary relief. On presentation to a tertiary hospital, careful and comprehensive history taking found that the sciatica pattern of pain always coincided with menstruation. An MRI identified a thickened left sciatic nerve, with surgery confirming sciatic nerve endometriosis. The case highlights the importance of comprehensive history taking in accurately diagnosing a rare aetiology of sciatica with subsequent prompt surgical intervention to avoid severe disability as well as follow-up treatment to prevent recurrence.<\/jats:p>","DOI":"10.1136\/bcr-2021-244584","type":"journal-article","created":{"date-parts":[[2021,8,25]],"date-time":"2021-08-25T13:10:39Z","timestamp":1629897039000},"page":"e244584","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Endometriosis of the sciatic nerve masquerading as lumbar spondylosis in a 40-year-old Chinese woman"],"prefix":"10.1136","volume":"14","author":[{"given":"Ankith","family":"Nair","sequence":"first","affiliation":[{"name":"Curtin Medical School, Faculty of Health Sciences, Curtin University, Perth, Western Australia, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian Tao","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Microsurgery and Plastic Surgery, The First Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6649-1111","authenticated-orcid":false,"given":"Dan","family":"Xu","sequence":"additional","affiliation":[{"name":"Curtin Medical School, Faculty of Health Sciences, Curtin University, Perth, Western Australia, Australia"},{"name":"Medical Education & General Practice, The First Affiliated Hospital, Sun Yat-sen University, Guangzhou, China"},{"name":"Curtin School of Population Health, Faculty of Health Sciences, Curtin University, Perth, Western Australia, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qing-Tang","family":"Zhu","sequence":"additional","affiliation":[{"name":"Department of Microsurgery and Plastic Surgery, The First Affiliated Hospital, Sun Yat-Sen University, Guangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,8,25]]},"reference":[{"key":"2025082723455501000_14.8.e244584.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2012.06.029"},{"key":"2025082723455501000_14.8.e244584.2","doi-asserted-by":"crossref","first-page":"822","DOI":"10.1016\/j.jmig.2017.02.027","article-title":"Five-year follow-up after laparoscopic large nerve resection for deep infiltrating sciatic nerve endometriosis","volume":"24","author":"Possover","year":"2017","journal-title":"J Minim Invasive Gynecol"},{"key":"2025082723455501000_14.8.e244584.3","doi-asserted-by":"crossref","first-page":"81","DOI":"10.4103\/GMIT.GMIT_24_18","article-title":"Endometriosis involving the sciatic nerve: a case report of isolated endometriosis of the sciatic nerve and review of the literature","volume":"7","author":"Saar","year":"2018","journal-title":"Gynecol Minim Invasive Ther"},{"key":"2025082723455501000_14.8.e244584.4","doi-asserted-by":"crossref","unstructured":"Schenken R .
