Given the limited extent of this patient\u2019s osteoarthritis and the absence of infectious signs or symptoms, both of which are typically related to gas collections at the hip, it was difficult to determine the aetiology of the patient\u2019s gas collection, whether it was related to her pain, and how best to manage her symptoms. Even in the setting of her MRI findings, which showed the gas collection lifting the iliopsoas tendon off the bone, the gas-containing bursa ultimately appeared to be a minor component of the patient\u2019s pain and definitive treatment of her underlying joint disease with a total hip arthroplasty allowed for successful pain management. Our case report demonstrates an unusual presentation of iliopsoas bursitis with a surprising response to medical, interventional and surgical management.<\/jats:p>","DOI":"10.1136\/bcr-2019-233045","type":"journal-article","created":{"date-parts":[[2020,2,10]],"date-time":"2020-02-10T04:39:23Z","timestamp":1581309563000},"page":"e233045","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Gas-containing iliopsoas bursitis in the setting of degenerative osteoarthritis"],"prefix":"10.1136","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7862-8282","authenticated-orcid":false,"given":"Lauren","family":"Raymond","sequence":"first","affiliation":[{"name":"Anesthesiology and Perioperative Medicine, Oregon Health & Science University, Portland, Oregon, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandy","family":"Christiansen","sequence":"additional","affiliation":[{"name":"Anesthesiology and Perioperative Medicine, Oregon Health & Science University, Portland, Oregon, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2020,2,9]]},"reference":[{"key":"2025082723213203000_13.2.e233045.1","doi-asserted-by":"publisher","DOI":"10.1007\/s003300101041"},{"key":"2025082723213203000_13.2.e233045.2","first-page":"15","article-title":"An atypical case of noninfected iliopsoas bursitis - MRI findings","volume":"3","author":"Skiadas","year":"2009","journal-title":"J Radiol Case Rep"},{"key":"2025082723213203000_13.2.e233045.3","doi-asserted-by":"crossref","first-page":"173","DOI":"10.1097\/00003086-196609000-00023","article-title":"Pathogenesis and treatment of ganglion","volume":"48","author":"Soren","year":"1966","journal-title":"Clin Orthop Relat Res"},{"key":"2025082723213203000_13.2.e233045.4","doi-asserted-by":"crossref","first-page":"395","DOI":"10.1016\/S0033-8389(22)00475-4","article-title":"Ganglia and cysts around joints","volume":"34","author":"Steiner","year":"1996","journal-title":"Radiol Clin North Am"},{"key":"2025082723213203000_13.2.e233045.5","doi-asserted-by":"publisher","DOI":"10.5312\/wjo.v6.i9.688"},{"key":"2025082723213203000_13.2.e233045.6","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.139.2.7220878"},{"key":"2025082723213203000_13.2.e233045.7","doi-asserted-by":"publisher","DOI":"10.1097\/00004728-198208000-00002"},{"key":"2025082723213203000_13.2.e233045.8","doi-asserted-by":"crossref","unstructured":"Mehdi A , Amenta P , Harrop J .
