They mostly occur in the thoracic region and occasionally are thoracolumbar in location. Typically, patients may be asymptomatic or exhibit pain with\/without a neurological deficit.<\/jats:p>\n <\/jats:sec>\n \n Case Description:<\/jats:title>\n A 44-year-old female presented with a 5-year history of chronic low back pain and intermittent dysesthesia but had no neurological deficits. The magnetic resonance revealed an extradural cyst at D12-L1, isointense to cerebrospinal fluid (CSF) and displacing the dural sac ventrally. The patient underwent a D12-L1 hemilaminectomy for excision of a thin-walled cyst; there were adhesions to the conus, and we encountered no CSF leakage. Postoperatively, pain rapidly improved, and the patient remains asymptomatic.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n A 44-year-old female presented with pain attributed to a T12-L1 dorsal extradural cyst that was successfully removed through a hemilaminectomy, resulting in full resolution of her pain complaints.<\/jats:p>\n <\/jats:sec>","DOI":"10.25259\/sni_1311_2025","type":"journal-article","created":{"date-parts":[[2026,2,6]],"date-time":"2026-02-06T07:29:36Z","timestamp":1770362976000},"page":"67","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Spinal extradural arachnoid cyst in the dorsolumbar region: A case report and literature review"],"prefix":"10.25259","volume":"17","author":[{"given":"Juan Pedro","family":"Murillo Gutierrez","sequence":"first","affiliation":[{"name":"Neurosurgery Service, Hospital Regional Honorio Delgado Espinoza, Arequipa, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Albert Gabriel","family":"Turpo-Peqque\u00f1a","sequence":"additional","affiliation":[{"name":"Department of Human Medicine, Faculty of Human Medicine, Universidad Catolica de Santa Maria, Arequipa, Peru"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10894","published-online":{"date-parts":[[2026,2,6]]},"reference":[{"key":"10.25259\/SNI_1311_2025\/ref-1","doi-asserted-by":"crossref","first-page":"736","DOI":"10.21037\/jss-20-590","article-title":"Extradural arachnoid cyst with bony erosion: A rare case report","volume":"6","author":"Bowman","year":"2020","journal-title":"J Spine Surg"},{"key":"10.25259\/SNI_1311_2025\/ref-2","doi-asserted-by":"crossref","first-page":"93","DOI":"10.1016\/S0025-6196(26)01413-8","article-title":"Idiopathic (\u201ccongenital\u201d) spinal arachnoid diverticula.
