Physical examination was remarkable for only scleral icterus. Laboratory evaluation revealed elevated aminotransferases, alkaline phosphatase and bilirubin. Imaging demonstrated two masses in the right lobe of his liver, which were ultimately drained and cultures demonstrated <jats:italic>Actinomyces<\/jats:italic> and <jats:italic>Eikenella<\/jats:italic>. He continued to have fever on broad-spectrum antibiotics until catheter drainage of the abscesses was performed. He was eventually discharged in improved condition on amoxicillin-clavulanate. His aminotransferases, alkaline phosphatase and bilirubin continued to improve and he remained afebrile and asymptomatic. A repeat CT 2\u2005months after discharge demonstrated resolution of the abscesses. <jats:italic>Actinomyces<\/jats:italic> and <jats:italic>Eikenella<\/jats:italic> are rare causes of liver abscesses and treatment requires drainage and an extended course of antibiotics. The polymicrobial character typical of liver abscesses makes antibiotic therapy challenging when cultures reveal rare organisms such as <jats:italic>Actinomyces<\/jats:italic> and <jats:italic>Eikenella<\/jats:italic>.<\/jats:p>","DOI":"10.1136\/bcr-2013-009613","type":"journal-article","created":{"date-parts":[[2013,7,18]],"date-time":"2013-07-18T01:41:21Z","timestamp":1374111681000},"page":"bcr2013009613","source":"Crossref","is-referenced-by-count":9,"title":["<i>Actinomyces naeslundii<\/i> and <i>Eikenella corrodens<\/i> as rare causes of liver abscesses"],"prefix":"10.1136","volume":"2013","author":[{"given":"Nathan Thomas","family":"Jaqua","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam J","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Terry T","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jay","family":"Jahanmir","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Tripler Army Medical Center, Honolulu, Hawaii, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,7,17]]},"reference":[{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.1","first-page":"267","article-title":"Acute diverticulitis\u2014an unusual cause of liver abcesses in a young man: a case report","volume":"2013","author":"Al Hajjar","year":"2012","journal-title":"Chirurgia (Bucur)"},{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.2","first-page":"xxiv","article-title":"Pyogenic liver abscess after colonoscopy in a patient with ulcerative colitis","volume":"2013","author":"Wells","year":"2005","journal-title":"Clin Gastroenterol Hepatol"},{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.3","doi-asserted-by":"crossref","first-page":"750","DOI":"10.3346\/jkms.2007.22.4.750","article-title":"Combined hepatic and splenic abscesses in a patient with ulcerative colitis","volume":"2013","author":"Ji","year":"2007","journal-title":"J Korean Med Sci"},{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.4","first-page":"208","article-title":"Acute abdomen due to eosinophilic colitis with liver abscess","volume":"2013","author":"Kandaswamy","year":"2006","journal-title":"Indian J Gastroenterol"},{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.5","doi-asserted-by":"crossref","first-page":"228","DOI":"10.1016\/j.jfma.2012.03.001","article-title":"Hepatosplenic actinomycosis in an immunocompetent patient","volume":"2013","author":"Wang","year":"2012","journal-title":"J Formos Med Assoc"},{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.6","first-page":"104","article-title":"Solitary actinomycotic abscesses of liver: report of two cases","volume":"2013","author":"Chen","year":"2006","journal-title":"Int J Clin Pract"},{"key":"2025082805202344000_2013.jul17_1.bcr2013009613.7","doi-asserted-by":"crossref","first-page":"319","DOI":"10.1016\/S0046-8177(73)80097-8","article-title":"Human actinomycosis.
