Magnetic resonance imaging revealed joint effusion and myositis in surrounding muscles. Joint aspiration confirmed Methicillin-resistant Staphylococcus aureus septic arthritis. Despite intravenous antibiotics, a growing intramuscular abscess in the gastrocnemius was detected on serial ultrasound. Surgical drainage was performed. The patient was treated with IV vancomycin for 2 weeks, followed by oral linezolid, and recovered fully.\n\nConclusion: Pyomyositis should be considered in septic arthritis with atypical presentations. Serial imaging and inflammatory markers are essential for guiding treatment.\n\nKeywords: Methicillin-resistant Staphylococcus aureus, septic arthritis, pyomyositis, gastrocnemius, vancomycin, C-reactive protein, immunocompetent, knee joint.<\/jats:p>","DOI":"10.13107\/jocr.2026.v16.i07.7696","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T05:34:30Z","timestamp":1783661670000},"page":"378-382","source":"Crossref","is-referenced-by-count":0,"title":["Atypical Presentation of MRSA Septic Arthritis with Concurrent Pyomyositis of the Calf Muscles in an Immunocompetent Adult"],"prefix":"10.13107","volume":"16","author":[{"given":"Sameer","family":"Tyagi","sequence":"first","affiliation":[{"name":"Department of Orthopedics, Holy Family Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dylan","family":"Goveas","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Holy Family Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanah","family":"Merchant","sequence":"additional","affiliation":[{"name":"Infectious Disease Unit, Holy Family Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russell","family":"Pinto","sequence":"additional","affiliation":[{"name":"Department of General Surgery, Holy Family Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gurmeet","family":"Sawhney","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Holy Family Hospital, Mumbai, Maharashtra, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"5271","published-online":{"date-parts":[[2026]]},"container-title":["Journal of Orthopaedic Case Reports"],"original-title":[],"deposited":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T05:34:31Z","timestamp":1783661671000},"score":1,"resource":{"primary":{"URL":"https:\/\/jocr.co.in\/wp\/2026\/07\/atypical-presentation-of-mrsa-septic-arthritis-with-concurrent-pyomyositis-of-the-calf-muscles-in-an-immunocompetent-adult\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":0,"journal-issue":{"issue":"7","published-online":{"date-parts":[[2026]]},"published-print":{"date-parts":[[2026]]}},"URL":"https:\/\/doi.org\/10.13107\/jocr.2026.v16.i07.7696","relation":{},"ISSN":["2321-3817"],"issn-type":[{"value":"2321-3817","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]}}}
