The authors present the case of a previously healthy male adolescent, with complaints of fatigue and chest pain, who was diagnosed with <jats:italic>Enterococcus faecalis<\/jats:italic>-associated acute primary lung abscess.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Case presentation<\/jats:title>\n                <jats:p>A previously healthy 17-year old boy was admitted to the pediatric ward due to a one-week history of fatigue, inspiratory left side chest pain, dry cough and nasal obstruction. On admission at the emergency department, he was afebrile, with no signs of respiratory distress, but with diminished breath sounds on the left side. A chest x-ray showed a round opacity on the posterior basal segment of the left lower lobe; he was discharged with oral amoxicillin 1000\u2009mg three times a day with the diagnosis of community-acquired pneumonia. Due to the worsening of the productive cough with purulent stinking sputum he was re-evaluated after 4 days. Laboratory studies showed a leukocyte count of 15200\/uL and a c-reactive protein of 172\u2009mg\/l. The chest computed tomography scan was suggestive of a consolidation of the left lower lobe base and a central abscess. An intravenous course of ceftriaxone and clindamycin was initiated, with a favourable clinical evolution. The bronchofibroscopy performed on day four after his admission revealed the presence of a tracheal bronchus and numerous purulent secretions. Culture examination of bronchoalveolar lavage fluid samples was positive (&gt;\u200910^5) for <jats:italic>Enterococcus faecalis<\/jats:italic>. No complications were registered during his stay in the pediatric ward. He was discharged after a 14-day course of intravenous ceftriaxone and clindamycin, with the recommendation to complete a four-week course of oral amoxicillin\/clavulanic acid. On his reevaluation 4 weeks after his discharge, he was asymptomatic.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>This case report highlights the importance of considering <jats:italic>Enterococcus faecalis<\/jats:italic> as an etiologic agent in cases of non-resolving or complicated cases of pneumonia, such as lung abscesses, even in young patients with no comorbidities or risk factors.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1186\/s12887-020-2003-8","type":"journal-article","created":{"date-parts":[[2020,3,2]],"date-time":"2020-03-02T17:13:04Z","timestamp":1583169184000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Enterococcus faecalis-associated lung abscess in a male adolescent- a case report"],"prefix":"10.1186","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8310-2525","authenticated-orcid":false,"given":"Ana Raquel","family":"Mendes","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ant\u00f3nio","family":"Costa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helena","family":"Ferreira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristina","family":"Ferreira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2020,3,2]]},"reference":[{"key":"2003_CR1","doi-asserted-by":"publisher","first-page":"j686","DOI":"10.1136\/bmj.j686","volume":"356","author":"IJ Ha","year":"2017","unstructured":"Ha IJ, Battersby AC, Eastham K, McKean M.
