It is often associated with dyspnoea. In severe cases, bronchial stenosis results in airflow obstruction, impaired secretion clearance, and can lead to respiratory failure. We present an unusual observation of platypnoea\u2013orthodeoxia syndrome in a young woman with acute atelectasis due to post\u2010tuberculosis bronchial stricture. Imaging revealed complete middle and right lower lobe atelectasis with a partially aerated right upper lobe. In the sitting posture, there was positional worsening of dyspnoea associated with an increase in the alveolar\u2010arterial oxygen gradient and shunt fraction. The likely mechanism was due to gravitational difference in ventilation\u2013perfusion matching. The platypnoea\u2013orthodeoxia syndrome was reversible following balloon dilatation of the bronchial stenosis and expansion of the collapsed lung.<\/jats:p>","DOI":"10.1002\/rcr2.303","type":"journal-article","created":{"date-parts":[[2018,2,7]],"date-time":"2018-02-07T14:02:43Z","timestamp":1518012163000},"source":"Crossref","is-referenced-by-count":2,"title":["Reversible platypnoea\u2013orthodeoxia syndrome in post\u2010tuberculosis bronchial stenosis"],"prefix":"10.1002","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2566-9854","authenticated-orcid":false,"given":"Geak Poh","family":"Tan","sequence":"first","affiliation":[{"name":"Department of Respiratory and Critical Care Medicine Tan Tock Seng Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John Arputhan","family":"Abisheganaden","sequence":"additional","affiliation":[{"name":"Department of Respiratory and Critical Care Medicine Tan Tock Seng Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Soon Keng","family":"Goh","sequence":"additional","affiliation":[{"name":"Department of Respiratory and Critical Care Medicine Tan Tock Seng Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7000-8708","authenticated-orcid":false,"given":"Akash","family":"Verma","sequence":"additional","affiliation":[{"name":"Department of Respiratory and Critical Care Medicine Tan Tock Seng Hospital  Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,2,7]]},"reference":[{"issue":"1","key":"e_1_2_4_2_1","doi-asserted-by":"crossref","first-page":"E71","DOI":"10.21037\/jtd.2017.01.49","article-title":"Tracheobronchial tuberculosis: a clinical review","volume":"9","author":"Siow WT","year":"2017","journal-title":"J.
