The full spectrum of causative agents and the underlying pathogenesis remain poorly understood. A 4-year-old spayed indoor cat presented with a one-week history of fever and anorexia. Laboratory tests revealed marked neutrophilia, eosinophilia, and an elevated feline serum amyloid A level. Computed tomography identified cyst-like masses in the medial iliac and hepatic lymph nodes. Cytological analysis showed infiltration by neutrophils and macrophages without neoplastic cells. Gram-positive cocci were observed, and\n                    <jats:italic>Staphylococcus aureus<\/jats:italic>\n                    was isolated from the abscesses. Based on antimicrobial susceptibility testing, amoxicillin was selected as the treatment. Administration of amoxicillin led to clinical improvement and normalization of hematological abnormalities. Antibiotic therapy was continued for approximately 6\u2009months, after which no recurrence was observed. The cat remained in good health at 689\u2009days after the initial presentation. This is the first reported case of multiple intra-abdominal LAs caused by\n                    <jats:italic>S. aureus<\/jats:italic>\n                    in a cat. The case highlights the pathogenic potential of this commensal bacterium and underscores the importance of long-term, susceptibility-guided antibiotic therapy in achieving complete resolution.\n                  <\/jats:p>","DOI":"10.3389\/fvets.2025.1654990","type":"journal-article","created":{"date-parts":[[2025,11,17]],"date-time":"2025-11-17T14:49:16Z","timestamp":1763390956000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Case Report: Multiple intra-abdominal lymph node abscesses due to Staphylococcus aureus in a cat"],"prefix":"10.3389","volume":"12","author":[{"given":"Kei","family":"Tamura","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kazuya","family":"Kushida","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoko","family":"Iwanaga","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryuji","family":"Fukushima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keitaro","family":"Ohmori","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2025,11,17]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"20551169231208896","DOI":"10.1177\/20551169231208896","article-title":"Bacterial pericarditis associated with a hepatic abscess in a cat","volume":"9","author":"White","year":"2023","journal-title":"JFMS Open Rep"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"484","DOI":"10.1177\/1098612X15613388","article-title":"Renal abscesses in cats: six cases","volume":"19","author":"Faucher","year":"2017","journal-title":"J Feline Med Surg"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"1146","DOI":"10.1292\/jvms.17\u20130026","article-title":"Pancreatic abscess in a cat due to Staphylococcus aureus infection","volume":"79","author":"Nemoto","year":"2017","journal-title":"J Vet Med Sci"},{"key":"ref4","doi-asserted-by":"publisher","first-page":"1611","DOI":"10.1002\/vms3.840","article-title":"Mesenteric lymph node abscesses due to Escherichia coli in a cat","volume":"8","author":"Sakai","year":"2022","journal-title":"Vet Med Sci"},{"key":"ref5","doi-asserted-by":"publisher","first-page":"1753","DOI":"10.1111\/jvim.15539","article-title":"Listerial mesenteric lymphadenitis in 3 cats","volume":"33","author":"Fluen","year":"2019","journal-title":"J Vet Intern Med"},{"key":"ref6","doi-asserted-by":"publisher","first-page":"690","DOI":"10.1111\/jsap.12551","article-title":"Retrospective characterisation and outcome of canine idiopathic mesenteric purulent lymphadenitis and lymph node abscesses at a teaching hospital from 2005 to 2015","volume":"57","author":"Schmitz","year":"2016","journal-title":"J Small Anim Pract"},{"key":"ref7","doi-asserted-by":"publisher","first-page":"25","DOI":"10.2147\/VMRR.S238305","article-title":"Salmonella mesenteric lymphadenitis causing septic peritonitis in two dogs","volume":"11","author":"Binagia","year":"2020","journal-title":"Vet Med"},{"key":"ref8","doi-asserted-by":"publisher","first-page":"523","DOI":"10.2460\/javma.2005.226.523","article-title":"What is your diagnosis?
