Forearm involvement, especially in the supinator, is exceptionally uncommon and may cause nerve compression when near neurovascular structures. We report a rare case of a 47-year-old woman presenting with a gradually enlarging, painless mass in the dorsal aspect of the proximal left forearm and associated wrist drop. Imaging revealed a well-circumscribed, mucinous lesion within the supinator muscle. Histopathological evaluation confirmed the diagnosis of an IMM. The tumor was surgically excised, with intraoperative findings revealing compression of the posterior interosseous nerve. Postoperatively, the patient demonstrated progressive improvement in wrist extension without evidence of recurrence. This case highlights a rare presentation of IMM causing posterior interosseous nerve compression and wrist drop. Marginal excision is often curative given its benign nature. IMM should be considered in painless, slow-growing masses with motor deficits.<\/jats:p>","DOI":"10.1093\/jscr\/rjaf1017","type":"journal-article","created":{"date-parts":[[2025,12,5]],"date-time":"2025-12-05T13:44:17Z","timestamp":1764942257000},"source":"Crossref","is-referenced-by-count":1,"title":["Intramuscular myxoma of the supinator muscle causing posterior interosseous nerve palsy: a case report and review of literature"],"prefix":"10.1093","volume":"2025","author":[{"given":"Motaz","family":"AlAqeel","sequence":"first","affiliation":[{"name":"Department of Orthopedic Surgery, College of Medicine, King Saud University , PO Box 2925, Riyadh 11461 ,","place":["Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-8804-3743","authenticated-orcid":false,"given":"Mishari","family":"Alanezi","sequence":"additional","affiliation":[{"name":"College of Medicine, King Saud University , PO Box 2925, Riyadh 11461 ,","place":["Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nouf","family":"Alabdulkarim","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery, College of Medicine, King Saud University , PO Box 2925, Riyadh 11461 ,","place":["Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fahad","family":"Almehrij","sequence":"additional","affiliation":[{"name":"Orthopedic Department, Operation Program of Medical Cities, Ministry of Interior , PO Box 2925, Riyadh 11461 ,","place":["Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Norah","family":"Alromaih","sequence":"additional","affiliation":[{"name":"Orthopaedic Surgery Resident, King Saud Medical City , PO Box 2925, Riyadh 11461 ,","place":["Saudi Arabia"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2025,12,22]]},"reference":[{"key":"2025122210411800500_ref1","doi-asserted-by":"publisher","first-page":"1073","DOI":"10.1177\/000313480407001208","article-title":"Intramuscular myxomas: a clinicopathologic study with emphasis on surgical management","volume":"70","author":"Charron","year":"2004","journal-title":"Am Surg"},{"key":"2025122210411800500_ref2","doi-asserted-by":"publisher","first-page":"7","DOI":"10.1016\/j.ijcard.2011.12.052","article-title":"Cardiac myxoma the great imitators: comprehensive histopathological and molecular approach","volume":"164","author":"Go\u0161ev","year":"2013","journal-title":"Int J Cardiol"},{"key":"2025122210411800500_ref3","doi-asserted-by":"publisher","DOI":"10.1177\/2050313X231200120","article-title":"Intramuscular myxoma of the thigh: a case report","volume":"11","author":"Jabbar","year":"2023","journal-title":"SAGE Open Med Case Rep"},{"key":"2025122210411800500_ref4","doi-asserted-by":"publisher","first-page":"191","DOI":"10.1097\/00003086-200210000-00028","article-title":"Intramuscular myxoma: a clinicopathologic study of 17 patients","volume":"403","author":"Silver","year":"2002","journal-title":"Clin Orthop Relat Res"},{"key":"2025122210411800500_ref5","doi-asserted-by":"publisher","first-page":"892","DOI":"10.1007\/s43465-021-00367-9","article-title":"Surgical treatment of intramuscular myxoma","volume":"55","author":"Sukpanichyingyong","year":"2021","journal-title":"Indian J Orthop"},{"key":"2025122210411800500_ref6","doi-asserted-by":"publisher","first-page":"260","DOI":"10.3171\/spi.2001.95.2.0260","article-title":"Intramuscular myxoma causing lumbar radiculopathy.
