We report a case of an 80\u2010year\u2010old male with a 15\u2010year history of asymptomatic BD that gradually increased in size and eventually developed into an abscess. Chest computed tomography revealed a cystic lesion adjacent to the left main bronchus with internal fluid and surrounding inflammation. Endobronchial ultrasound\u2010guided transbronchial needle aspiration (EBUS\u2010TBNA) enabled safe aspiration and identification of alpha\u2010hemolytic <jats:italic>Streptococcus<\/jats:italic> despite the absence of a visible bronchial opening. The infection was successfully managed with antibiotics alone, thereby avoiding surgical intervention. This case highlights the potential for long\u2010term asymptomatic BD to develop infection and demonstrates the diagnostic utility of EBUS\u2010TBNA for lesions adjacent to vital structures. However, further studies are needed to clarify infection risk factors and optimal management strategies for BD.<\/jats:p>","DOI":"10.1002\/rcr2.70251","type":"journal-article","created":{"date-parts":[[2025,6,23]],"date-time":"2025-06-23T06:45:33Z","timestamp":1750661133000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Case of Bronchial Diverticulum With Progressive Enlargement and Abscess Formation Successfully Managed by Endobronchial Ultrasound\u2010Guided Transbronchial Needle Aspiration and Antibiotic Therapy"],"prefix":"10.1002","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3261-5483","authenticated-orcid":false,"given":"Hikaru","family":"Aoki","sequence":"first","affiliation":[{"name":"Department of Thoracic Surgery Ashikaga Red Cross Hospital  Ashikaga Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masaki","family":"Aikawa","sequence":"additional","affiliation":[{"name":"Department of Medicine Ashikaga Red Cross Hospital  Ashikaga Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshitomo","family":"Kushima","sequence":"additional","affiliation":[{"name":"Department of Medicine Ashikaga Red Cross Hospital  Ashikaga Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiro","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Department of Medicine Ashikaga Red Cross Hospital  Ashikaga Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshiyuki","family":"Shima","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery Ashikaga Red Cross Hospital  Ashikaga Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoju","family":"Kameyama","sequence":"additional","affiliation":[{"name":"Department of Medicine Ashikaga Red Cross Hospital  Ashikaga Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2025,6,22]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1093\/jscr\/rjaf223"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00330\u2010009\u20101526\u2010z"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1186\/s40792\u2010016\u20100282\u2010y"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijscr.2016.04.051"}],"container-title":["Respirology Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/rcr2.70251","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,6,26]],"date-time":"2025-06-26T15:59:14Z","timestamp":1750953554000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/rcr2.70251"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,6]]},"references-count":4,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2025,6]]}},"alternative-id":["10.1002\/rcr2.70251"],"URL":"https:\/\/doi.org\/10.1002\/rcr2.70251","archive":["Portico"],"relation":{},"ISSN":["2051-3380","2051-3380"],"issn-type":[{"type":"print","value":"2051-3380"},{"type":"electronic","value":"2051-3380"}],"subject":[],"published":{"date-parts":[[2025,6]]},"assertion":[{"value":"2025-06-04","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-06-07","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-06-22","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70251"}}
