Case Presentation: This case report describes a 28-year-old primigravida who developed unilateral Horner\u2019s syndrome approximately one hour after lumbar epidural analgesia placement for labour pain relief. Upon examination the patient presented with left-sided ptosis, anisocoria, and unexpected sensory blockade extending to the T3\u2013T4 level, accompanied by localised numbness in the left breast and transient upper limb paraesthesia. The pathophysiology of Horner\u2019s syndrome involves cephalad spread of local anaesthetic toward the superior cervical sympathetic chain, disrupting sympathetic innervation to the ocular and facial areas. Primary and secondary damage to the sympathetic pathways in the central nervous offer a wide differential diagnosis. The management was conservative, including reduction in epidural bolus infusion rates and careful monitoring. The patient experienced complete resolution of all symptoms within five hours and delivered vaginally without complications. Conclusions: This case demonstrates the characteristically benign and self-limited nature of this complication, emphasising the importance of clinical awareness, proper reassurance of patients, and avoidance of unnecessary diagnostic testing.<\/jats:p>","DOI":"10.3390\/reports9030289","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T12:27:46Z","timestamp":1787920066000},"page":"289","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Case Report of Horner\u2019s Syndrome in Labour Neuroaxial Analgesia: Diagnosis, Management and Follow-Up"],"prefix":"10.3390","volume":"9","author":[{"given":"Yong-Shun","family":"Thoo","sequence":"first","affiliation":[{"name":"Emergency Department, Vaud University Hospital (CHUV), 1005 Lausanne, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana","family":"Fernandes","sequence":"additional","affiliation":[{"name":"Service of Anaesthesiology and Reanimation, Geneva University Hospital (HUG), 1205 Geneva, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Joe","family":"Dib","sequence":"additional","affiliation":[{"name":"Service of Anaesthesiology and Reanimation, Fribourg Hospital, 1708 Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corinne","family":"Grandjean","sequence":"additional","affiliation":[{"name":"Service of Anaesthesiology and Reanimation, Fribourg Hospital, 1708 Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-9773-1243","authenticated-orcid":false,"given":"Ouanes Amine","family":"Ben Saad","sequence":"additional","affiliation":[{"name":"Service of Anaesthesiology and Reanimation, Fribourg Hospital, 1708 Fribourg, Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,8,28]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1473","DOI":"10.1212\/WNL.51.5.1473","article-title":"Transient Horner\u2019s syndrome after lumbar epidural anesthesia","volume":"51","author":"Biousse","year":"1998","journal-title":"Neurology"},{"key":"ref_2","first-page":"583","article-title":"The incidence of Homer\u2019s syndrome during lumbar extradural for elective Caesarean section and provision of analgesia during labour","volume":"38","author":"Clayton","year":"1983","journal-title":"Anaesthesia"},{"key":"ref_3","first-page":"e48666","article-title":"Horner\u2019s Syndrome Following Dural Puncture Epidural Analgesia for Labor","volume":"15","author":"Mirkarimi","year":"2023","journal-title":"Cureus"},{"key":"ref_4","unstructured":"Khan, Z., and Bollu, P.C.
