We report a case of a woman in her 80s without substantial medical history who presented with a headache, weakness and personality changes, and was found to have a pyogenic brain abscess requiring emergent neurosurgical evacuation. The abscess grew oral flora, suspected to have reached the brain via an incidentally discovered PAVM. With drainage and antibiotics, the patient achieved a full recovery and the PAVM was embolised. To our knowledge, this is the oldest presentation of a PAVM-associated brain abscess in the published literature. Older patients may present without the typical signs and symptoms of a given illness, which complicates accurate diagnosis and treatment. Primary care physicians can help facilitate timely care and positive clinical outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2022-252794","type":"journal-article","created":{"date-parts":[[2022,11,16]],"date-time":"2022-11-16T09:55:28Z","timestamp":1668592528000},"page":"e252794","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Pyogenic brain abscess associated with an incidental pulmonary arteriovenous malformation"],"prefix":"10.1136","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8065-229X","authenticated-orcid":false,"given":"Kara Morgan","family":"Ryan","sequence":"first","affiliation":[{"name":"Internal Medicine, Weill Cornell Medicine, New York, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eugenia","family":"Siegler","sequence":"additional","affiliation":[{"name":"Geriatrics, Weill Cornell Medical College, New York, New York, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2022,11,16]]},"reference":[{"key":"2025082700013063000_15.11.e252794.1","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.158.2.9711041"},{"key":"2025082700013063000_15.11.e252794.2","doi-asserted-by":"crossref","DOI":"10.3389\/fmicb.2020.00826","article-title":"From Normal Flora to Brain Abscesses: A Review of Streptococcus intermedius","volume":"11","author":"Issa","year":"2020","journal-title":"Front Microbiol"},{"key":"2025082700013063000_15.11.e252794.3","doi-asserted-by":"publisher","DOI":"10.1159\/000487057"},{"key":"2025082700013063000_15.11.e252794.4","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.169.3.3186989"},{"key":"2025082700013063000_15.11.e252794.5","doi-asserted-by":"crossref","first-page":"595","DOI":"10.1093\/cid\/cix373","article-title":"Cerebral abscess associated with odontogenic bacteremias, hypoxemia, and iron loading in immunocompetent patients with right-to-left shunting through pulmonary arteriovenous malformations","volume":"65","author":"Boother","year":"2017","journal-title":"Clin Infect Dis"},{"key":"2025082700013063000_15.11.e252794.6","doi-asserted-by":"crossref","unstructured":"Jubelt B .
