Physical examination and MRI examination showed findings compatible with pyogenic sacroiliitis and an abscess in the left iliopsoas muscle. The patient's clinical and radiological findings improved markedly with empirical antibiotic treatment. Although immune system disorders associated with PKU have been reported previously, to our knowledge, a direct link between PKU and rheumatological diseases has not yet been demonstrated. This case suggests that further research is needed to understand the potential effects of PKU on the immune system and susceptibility to infections.<\/jats:p>","DOI":"10.1111\/1756-185x.70049","type":"journal-article","created":{"date-parts":[[2025,1,10]],"date-time":"2025-01-10T07:46:48Z","timestamp":1736495208000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Concurrent
