Distal to the atresia, a mucocele can form with consecutive hyperinflation of the peripheral lung parenchyma. We describe an asymptomatic patient with a well-demarcated segmental emphysematous area within the right lower lobe revealed by computed tomography (CT). Here, the right lateral basal segmental bronchus (B9) is proximally interrupted while the distal, mucus-filled bronchus forms a bronchocele. The down-stream segmental parenchyma is hyperinflated. 3D reconstruction of the tracheobronchial tree reveals a normal architecture of the tracheobronchial tree except for the characteristic discontinuation of the right ninth bronchus. Asymptomatic patients with BA do not require treatment, however, follow-up CT is recommended to assess stability of the segmental hyperinflation.<\/jats:p>","DOI":"10.3390\/diagnostics16131966","type":"journal-article","created":{"date-parts":[[2026,6,25]],"date-time":"2026-06-25T01:03:56Z","timestamp":1782349436000},"page":"1966","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bronchial Atresia of the Right Ninth Bronchus with Segmental Hyperinflation in an Asymptomatic Adult\u2014A Case"],"prefix":"10.3390","volume":"16","author":[{"given":"Wolfgang","family":"Jungraithmayr","sequence":"first","affiliation":[{"name":"Division of Thoracic Surgery, Rostock University Medical Center, Schillingallee 35, 18057 Rostock, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Birte","family":"Ohm","sequence":"additional","affiliation":[{"name":"Department of Thoracic Surgery, Medical Faculty, RWTH Aachen University, 52074 Aachen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jakob","family":"Neubauer","sequence":"additional","affiliation":[{"name":"Department of Diagnostic and Interventional Radiology, Medical Center\u2014University of Freiburg, Faculty of Medicine, University of Freiburg, 79106 Freiburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1136\/thx.26.1.68","article-title":"Bronchial atresia with corresponding segmental pulmonary emphysema","volume":"26","author":"Lacquet","year":"1971","journal-title":"Thorax"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"681","DOI":"10.1259\/0007-1285-65-776-681","article-title":"The radiological imaging of bronchial atresia","volume":"65","author":"Kinsella","year":"1992","journal-title":"Br.
