Non-typhoidal <i>Salmonella</i> (NTS) species show a tropism for the diseased aorta in elderly, atherosclerotic patients, causing explosive growth poorly captured by conventional surveillance. Management is complex when the visceral/paravisceral aorta is involved, making open surgical repair (OSR) risky and requiring tailored endovascular aortic repair (EVAR). This review synthesises evidence on <i>Salmonella</i>-associated MAAs and introduces hyper-rapid progression (HRP) as an early imaging biomarker.</p><p><strong>Conclusions: </strong>Salmonella MAAs represent a high-velocity phenotype. We define HRP as progression from aortitis to saccular pseudoaneurysm (≥ 5 mm) within 7 days or rapid enlargement (≥ 5 mm or > 50%) within 72 hours despite antibiotics. HRP serves as a \"red flag\" for urgent mechanical stabilisation. While OSR is the gold standard, in anatomically complex or high-risk patients, complex EVAR with parallel grafts and an optimized radial sealing strategy (ORSS) offers a life-saving alternative. Prospective validation of HRP and its integration into imaging algorithms are needed to improve survival in this devastating condition.</p>","PeriodicalId":21034,"journal":{"name":"Radiology and Oncology","volume":"60 1","pages":"22-31"},"PeriodicalIF":2.2,"publicationDate":"2026-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13012376/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147514402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
