In rare cases, these anaerobic gram-negative bacilli have been reported to cause pyogenic liver abscesses (PLAs). We describe a patient who developed a periodontal abscess during the COVID-19 pandemic and was unable to access the restricted General Dental Services at this time. She subsequently developed a <jats:italic>F. nucleatum<\/jats:italic> bacteraemia and liver abscess. The non-specific signs and symptoms experienced meant the patient self-isolated due to suspected COVID-19 infection and presentation to hospital was delayed. We also include the results of a literature search of other cases of PLAs attributed to <jats:italic>F. nucleatum<\/jats:italic>. PLAs often develop insidiously. They require percutaneous drainage and prolonged antimicrobial therapy. Clinicians should be aware of this rare complication of a dentoalveolar infection in a patient who is systemically unwell.<\/jats:p>","DOI":"10.1136\/bcr-2020-240080","type":"journal-article","created":{"date-parts":[[2021,1,26]],"date-time":"2021-01-26T12:42:41Z","timestamp":1611664961000},"page":"e240080","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["<i>Fusobacterium nucleatum<\/i> causing a pyogenic liver abscess: a rare complication of periodontal disease that occurred during the COVID-19 pandemic"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0895-2244","authenticated-orcid":false,"given":"Laurence","family":"Collins","sequence":"first","affiliation":[{"name":"Hepatobiliary Surgery, Mater Infirmorum Hospital, Belfast, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom","family":"Diamond","sequence":"additional","affiliation":[{"name":"Hepatobiliary Surgery, Mater Hospital, Belfast, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,1,26]]},"reference":[{"key":"2025082710441217000_14.1.e240080.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mib.2014.11.013"},{"key":"2025082710441217000_14.1.e240080.2","doi-asserted-by":"crossref","DOI":"10.1186\/s12879-017-2548-9","article-title":"Fusobacterial liver abscess: a case report and review of the literature","volume":"17","author":"Jayasimhan","year":"2017","journal-title":"BMC Infect Dis"},{"key":"2025082710441217000_14.1.e240080.3","doi-asserted-by":"crossref","DOI":"10.4103\/1947-2714.179961","article-title":"Fusobacterium nucleatum: atypical organism of pyogenic liver abscess might be related to sigmoid diverticulitis","volume":"8","author":"Wijarnpreecha","year":"2016","journal-title":"N Am J Med Sci"},{"key":"2025082710441217000_14.1.e240080.4","doi-asserted-by":"crossref","first-page":"241","DOI":"10.14740\/gr1006w","article-title":"Denture-Associated oral microbiome and periodontal disease causing an anaerobic pyogenic liver abscess in an immunocompetent patient: a case report and review of the literature","volume":"11","author":"Hammami","year":"2018","journal-title":"Gastroenterology Res"},{"key":"2025082710441217000_14.1.e240080.5","unstructured":"Scottish Dental Clinical Effectiveness Programme .
