The authors searched on PubMed and Scopus databases for published articles with the Mesh term \u201cspinal angiolipoma\u201d and pertinent associations. Language restriction to English papers was applied. The authors also reported three emblematic cases of patients who underwent surgical resection of spindle-shaped (type IA) and dumbbell-shaped (type II) SAs between 2014 and 2020.<\/jats:p><jats:p>\n          Results\u2003Of the 256 retrieved articles, 33 were included in the meta-analysis. These 33 studies, together with our 3 reported cases, included a total of 60 patients, 36 females (60%) and 24 males (40%), with a mean age of 53.12\u2009\u00b1\u200912.82 years (range: 12\u201377 years).<\/jats:p><jats:p>T5 was the most represented level (22 patients). Usually, the localization of SA was extradural, with 53 patients suffering from spindle-shaped type IA SA (88.3%) and 7 patients from dumbbell-shaped type II SA (11.6%). Almost all patients underwent laminectomy (78.3%) and presented a full recovery of motor deficits (85%). Gross total removal (GTR) was performed in 93.3% of patients. The mean follow-up was of 22.71\u2009\u00b1\u200921.45 months (range: 2\u201380 months). There was no documented recurrence at follow-up magnetic resonance imaging in any of the patients.<\/jats:p><jats:p>\n          Conclusions\u2003SAs are rare, benign tumors with a great vascular component that presents a favorable outcome. GTR is the gold standard treatment and usually an adjuvant therapy is not required. Even infiltrative lesions, which are more complex, can be treated successfully with a good prognosis. Dumbbell-shaped SAs must be differentiated from schwannomas and meningiomas, and require different surgical techniques, given the profuse bleeding associated with the attempt of debulking. En block resection is the key to treat these common benign tumors with acceptable blood loss.<\/jats:p>","DOI":"10.1055\/s-0041-1739217","type":"journal-article","created":{"date-parts":[[2021,12,20]],"date-time":"2021-12-20T23:37:32Z","timestamp":1640043452000},"page":"161-172","source":"Crossref","is-referenced-by-count":9,"title":["Thoracic Spinal Angiolipomas: A Systematic Review"],"prefix":"10.1055","volume":"83","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1573-431X","authenticated-orcid":false,"given":"Giuseppe Emmanuele","family":"Umana","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Cannizzaro Hospital, Catania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Massimiliano","family":"Visocchi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Policlinico Universitario Agostino Gemelli, Roma, Lazio, Italy"},{"name":"Catholic University of the Sacred Heart Rome Campus, Roma, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Roca","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Head and Neck Surgery, Poliambulanza Foundation Hospitals, Brescia, Lombardia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maurizio","family":"Passanisi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Azienda Ospedaliera Cannizzaro, Catania, Sicilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marco","family":"Fricia","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Cannizzaro Hospital, Catania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria Grazia","family":"Tranchina","sequence":"additional","affiliation":[{"name":"Department of Pathological Anatomy, Cannizzaro Hospital, Catania, Sicilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Santino Ottavio","family":"Tomasi","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Paracelsus Medical Private University, Salzburg, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni Federico","family":"Nicoletti","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Specialist Hospital Garibaldi, Catania, Sicilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Salvatore","family":"Cicero","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Cannizzaro Hospital, Catania, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9465-2506","authenticated-orcid":false,"given":"Gianluca","family":"Scalia","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, National Specialist Hospital Garibaldi, Catania, Sicilia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2021,12,20]]},"reference":[{"issue":"01","key":"ref1","doi-asserted-by":"crossref","first-page":"84","DOI":"10.1046\/j.1440-1673.2001.01001.x","article-title":"Spinal angiolipoma: report of three cases and review of MRI features","volume":"46","author":"A Garg","year":"2002","journal-title":"Australas Radiol"},{"issue":"02","key":"ref2","first-page":"93","article-title":"Infiltrating extradural spinal angiolipoma","volume":"18","author":"M Kujas","year":"1999","journal-title":"Clin Neuropathol"},{"issue":"04","key":"ref3","first-page":"253","article-title":"Spinal epidural angiolipoma","volume":"28","author":"S FA Amlashi","year":"2001","journal-title":"J Neuroradiol"},{"issue":"01","key":"ref4","doi-asserted-by":"crossref","first-page":"82","DOI":"10.1017\/S0317167100052628","article-title":"Spinal angiolipoma","volume":"28","author":"D R Fourney","year":"2001","journal-title":"Can J Neurol Sci"},{"issue":"05","key":"ref5","first-page":"1008","article-title":"MR imaging of an infiltrating spinal epidural angiolipoma","volume":"24","author":"N H Leu","year":"2003","journal-title":"AJNR Am J Neuroradiol"},{"issue":"03","key":"ref6","doi-asserted-by":"crossref","first-page":"720","DOI":"10.1002\/1097-0142(197409)34:3<720::AID-CNCR2820340331>3.0.CO;2-K","article-title":"Two entities in angiolipoma.
