Despite its commensal nature, underlying risk factors and medical conditions might lead to various anatomic site infections caused by this opportunistic pathogen. Although SC infections have mostly been associated with bacteremia, some case reports of abscess and empyema formation have been documented. Herein, we report a case of a middle-aged female patient who initially presented with radiculopathy symptoms. Subsequent neurologic imaging revealed a pyogenic abscess along paravertebral muscles, which was found to be caused by SC. The patient was successfully treated with abscess drainage from the lumbar zone and antibiotics, and the symptoms of radiculopathy have completely resolved.<\/jats:p>","DOI":"10.3390\/diagnostics12112686","type":"journal-article","created":{"date-parts":[[2022,11,4]],"date-time":"2022-11-04T03:28:10Z","timestamp":1667532490000},"page":"2686","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Aggressive Pyogenic Spondylitis Caused by S. constellatus: A Case Report"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7555-1155","authenticated-orcid":false,"given":"Nenad","family":"Koruga","sequence":"first","affiliation":[{"name":"Department of Neurosurgery, University Hospital Center Osijek, 31000 Osijek, Croatia"},{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4120-5737","authenticated-orcid":false,"given":"Alen","family":"Ron\u010devi\u0107","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, University Hospital Center Osijek, 31000 Osijek, Croatia"},{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anamarija","family":"Soldo Koruga","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Department of Neurology, University Hospital Center Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dario","family":"Sabadi","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Department of Infectious Diseases, University Hospital Center Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7348-6895","authenticated-orcid":false,"given":"Domagoj","family":"Drenjan\u010devi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Department of Infectious Diseases, University Hospital Center Osijek, 31000 Osijek, Croatia"},{"name":"Department of Microbiology, Parasitology and Clinical Laboratory Diagnostics, Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana","family":"Prica","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tatjana","family":"Rotim","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Department of Diagnostic and Interventional Radiology, University Hospital Center Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tajana","family":"Turk","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Department of Diagnostic and Interventional Radiology, University Hospital Center Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0279-0651","authenticated-orcid":false,"given":"Domagoj","family":"Kreti\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Josip Juraj Strossmayer University of Osijek, 31000 Osijek, Croatia"},{"name":"Department of Diagnostic and Interventional Radiology, University Hospital Center Osijek, 31000 Osijek, Croatia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,4]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Jorgensen, J.H., Carroll, K.C., Funke, G., Pfaller, M.A., Landry, M.L., Richter, S.S., Warnock, D.W., Carroll, K.C., Funke, G., and Bernard, K.A.
