Only a few cases have been reported in children until now and none were reported involving ribs. A female adolescent patient presented with swelling on the left upper back over the scapular region for the past 4\u2009years without any neurological deficit. MRI revealed a hyperintense lesion on the left paravertebral region extending from D5 to D12 and into the intercostal space, causing it to widen. The patient underwent surgical excision. The lipomatous mass was seen entering in to the intercostal space, causing it to widen. However, the pleura was not breached. In this report, we have performed a literature review compiling all cases of parosteal lipoma affecting the ribs.<\/jats:p>","DOI":"10.1136\/bcr-2023-257794","type":"journal-article","created":{"date-parts":[[2023,10,29]],"date-time":"2023-10-29T21:15:44Z","timestamp":1698614144000},"page":"e257794","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Parosteal
