Open head wounds and neurosurgical interventions are uncommon aetiologies. Ectopic tissue found in the cerebral cortex is usually ascribed almost entirely from carcinomas. Here, we describe a 57-year-old gentleman who, 22 years after a fireworks related traumatic injury to the left orbit, presented with headaches and altered behaviour. Imaging revealed an abscess immediately superior to the orbit, whose bacterial aetiology was identified to be <jats:italic>Pseudomonas aeruginosa,<\/jats:italic> encapsulated by ciliated respiratory epithelium. This represents a case in which tissue was displaced during the initial trauma or craniofacial reconstructive surgery from the frontal sinus.<\/jats:p>","DOI":"10.1136\/bcr-2020-238836","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T11:41:09Z","timestamp":1610710869000},"page":"e238836","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Ciliated respiratory epithelium encapsulating <i>Pseudomonas<\/i> brain abscess due to prior trauma"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7702-9034","authenticated-orcid":false,"given":"Nihar Kanta","family":"Jena","sequence":"first","affiliation":[{"name":"Internal Medicine, Saint Joseph Mercy Oakland Hospital, Pontiac, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Justin","family":"Khine","sequence":"additional","affiliation":[{"name":"Internal Medicine, Saint Joseph Mercy Oakland Hospital, Pontiac, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nadia","family":"Khosrodad","sequence":"additional","affiliation":[{"name":"Internal Medicine, Saint Joseph Mercy Oakland Hospital, Pontiac, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Geetha","family":"Krishnamoorthy","sequence":"additional","affiliation":[{"name":"Internal Medicine, Saint Joseph Mercy Oakland Hospital, Pontiac, Michigan, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,1,15]]},"reference":[{"key":"2025082701171513000_14.1.e238836.1","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.0000000000000172"},{"key":"2025082701171513000_14.1.e238836.2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra1301635"},{"key":"2025082701171513000_14.1.e238836.3","doi-asserted-by":"publisher","DOI":"10.1086\/515541"},{"key":"2025082701171513000_14.1.e238836.4","doi-asserted-by":"crossref","first-page":"477","DOI":"10.3171\/jns.2000.93.3.0477","article-title":"Brain abscess related to metal fragments 47 years after head injury.
