This patient presented with a 2-day history of hemisensory loss, hyper-reflexia and retro-orbital headache, 7\u2005days following a dental extraction for apical peridonitis. Neuroimaging showed a large left parietal abscess with surrounding empyema. The patient underwent craniotomy and drainage of the abscess. <jats:italic>A. meyeri<\/jats:italic> was cultured. Actinomycosis is a rare cause of cerebral abscess. The <jats:italic>A. meyeri<\/jats:italic> subtype is particularly rare, accounting for less than 1% of specimens. This case describes an unusually brief course of the disease, which is usually insidious. Parietal lobe involvement is unusual as cerebral abscesses usually have a predilection for the frontal and temporal regions of the brain. Although there are no randomised trials to guide therapy, current consensus is to use a prolonged course of intravenous antibiotics, followed by 6\u201312\u2005months of oral therapy.<\/jats:p>","DOI":"10.1136\/bcr-2014-207548","type":"journal-article","created":{"date-parts":[[2015,4,13]],"date-time":"2015-04-13T04:01:04Z","timestamp":1428897664000},"page":"bcr2014207548","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":15,"title":["<i>Actinomyces meyeri<\/i> brain abscess following dental extraction"],"prefix":"10.1136","volume":"2015","author":[{"given":"U","family":"Clancy","sequence":"first","affiliation":[{"name":"Cork University Hospital, Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Ronayne","sequence":"additional","affiliation":[{"name":"Cork University Hospital, Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M B","family":"Prentice","sequence":"additional","affiliation":[{"name":"Cork University Hospital, Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"Jackson","sequence":"additional","affiliation":[{"name":"Cork University Hospital\/Mercy University Hospital, Cork, Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,4,13]]},"reference":[{"key":"2025082803554975000_2015.apr13_1.bcr2014207548.1","doi-asserted-by":"publisher","DOI":"10.1016\/S1079-2104(98)90280-3"},{"key":"2025082803554975000_2015.apr13_1.bcr2014207548.2","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1978.00790120031005"},{"key":"2025082803554975000_2015.apr13_1.bcr2014207548.3","unstructured":"Crislip M .
