The sacrum is a rare site for SABC, and sacral lesions typically carry higher morbidity rates. Here, a 19-year-old female with a large primary multisegmental sacral SABC was successfully managed with 2-staged endovascular embolization.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>A 19-year-old female presented with progressive worsening of axial lumbosacral pain, and a left L5\/S1 radiculopathy. The lumbosacral computed tomography and magnetic resonance studies showed a large (10 cm [AP] \u00d7 11 cm [Tr] \u00d7 12 cm [CC]) heterogeneous, osteolytic lesion containing multiple fluid-fluid levels. The biopsy confirmed the diagnosis of a primary SABC. She was treated with a 2-staged endovascular embolization that resolved her pain. This was followed by radiographic confirmation of occlusion of the SABC.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st3\">\n<jats:title>Conclusion: <\/jats:title>\n<jats:p>A 19-year-old female presented with an atypical SABC that was successfully managed with 2-staged endovascular embolization.<\/jats:p>\n<\/jats:sec>","DOI":"10.25259\/sni_685_2023","type":"journal-article","created":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T06:04:45Z","timestamp":1697781885000},"page":"373","update-policy":"https:\/\/doi.org\/10.25259\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Giant sacral aneurysmal bone cyst treated with endovascular embolization"],"prefix":"10.25259","volume":"14","author":[{"given":"Samuel Sequeira","family":"Lemos","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, Hospital Santa Maria, Centro Hospitalar Lisboa Norte, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diogo","family":"Belo","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Hospital Santa Maria, Centro Hospitalar Lisboa Norte, Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Filipe Veloso","family":"Gomes","sequence":"additional","affiliation":[{"name":"Radiology Unit, Centro Hospitalar Lisboa Central, Lisboa, Portugal."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"10894","published-online":{"date-parts":[[2023,10,20]]},"reference":[{"key":"10.25259\/SNI_685_2023\/ref-1","first-page":"74","article-title":"Aneurysmal bone cysts of the sacrum: A report of ten cases and review of the literature","volume":"29","author":"Brastianos","year":"2009","journal-title":"Iowa Orthop J"},{"key":"10.25259\/SNI_685_2023\/ref-2","doi-asserted-by":"crossref","first-page":"523","DOI":"10.1007\/BF00195235","article-title":"Selective arterial embolization in the treatment of aneurysmal bone cyst and angioma of bone","volume":"21","author":"De Cristofaro","year":"1992","journal-title":"Skeletal Radiol"},{"key":"10.25259\/SNI_685_2023\/ref-3","doi-asserted-by":"crossref","first-page":"234","DOI":"10.3171\/2013.11.SPINE13412","article-title":"Serial endovascular embolization as stand-alone treatment of a sacral aneurysmal bone cyst","volume":"20","author":"Doss","year":"2014","journal-title":"J Neurosurg Spine"},{"key":"10.25259\/SNI_685_2023\/ref-4","doi-asserted-by":"crossref","first-page":"9","DOI":"10.1097\/00003086-198603000-00003","article-title":"A system of staging musculoskeletal neoplasms","volume":"204","author":"Enneking","year":"1986","journal-title":"Clin Orthop Relat Res"},{"key":"10.25259\/SNI_685_2023\/ref-5","first-page":"35","article-title":"Huge aneurysmal bone cyst of the sacrum","volume":"1","author":"Han","year":"2009","journal-title":"Korean J Spine"},{"key":"10.25259\/SNI_685_2023\/ref-6","first-page":"53","article-title":"Selective arterial embolisation of aneurysmal bone cysts of the sacrum: A promising alternative to surgery","volume":"188","author":"Henrichs","year":"2016","journal-title":"Fortschr R\u00f6ntgenstr"},{"key":"10.25259\/SNI_685_2023\/ref-7","doi-asserted-by":"crossref","first-page":"286","DOI":"10.1097\/01202412-199810000-00006","article-title":"Aneurysmal bone cyst of the spine","volume":"7","author":"Kleuver","year":"1998","journal-title":"J Pediatr Orthop B"},{"key":"10.25259\/SNI_685_2023\/ref-8","doi-asserted-by":"crossref","first-page":"1674","DOI":"10.2106\/00004623-200111000-00009","article-title":"Treatment of aneurysmal bone cysts of the pelvis and sacrum","volume":"83","author":"Papagelopoulos","year":"2001","journal-title":"J Bone Joint Surg Am"},{"key":"10.25259\/SNI_685_2023\/ref-9","doi-asserted-by":"crossref","first-page":"139","DOI":"10.1016\/j.trsl.2014.03.005","article-title":"Targeting receptor-activator of nuclear kappaB ligand in aneurysmal bone cysts: Verification of target and therapeutic response","volume":"164","author":"Pelle","year":"2014","journal-title":"Transl Res"},{"key":"10.25259\/SNI_685_2023\/ref-10","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1007\/s00402-003-0496-x","article-title":"Aneurysmal bone cysts of the sacrum.
