Hydropneumothorax is the abnormal collection of air and serous fluid within the pleural cavity. Here, we report a case of a 34-year-old male who presented to the emergency department with cough and breathlessness. We did bedside point-of-care ultrasound-assisted clinical evaluation as the patient was vitally unstable, which showed \u201chydro point\u201d and \u201cdefective barcode sign,\u201d which suggested hydropneumothorax. We present these clinical evaluation details, imaging\/sonographic findings, and patient management in this case report.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.4103\/2452-2473.342809","type":"journal-article","created":{"date-parts":[[2022,4,11]],"date-time":"2022-04-11T05:47:36Z","timestamp":1649656056000},"page":"108-110","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":2,"title":["Defective barcode sign \u2013 A newer sonographic sign in hydropneumothorax"],"prefix":"10.4103","volume":"22","author":[{"given":"Sasikumar","family":"Mahalingam","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gunaseelan","family":"Rajendran","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anuusha","family":"Sadasivam","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manu","family":"Ayyan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vivekanandan Muthu","family":"Pillai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"R1-8-20240909","doi-asserted-by":"crossref","first-page":"278","DOI":"10.4103\/0970-2113.180804","article-title":"Clinical profile, etiology, and management of hydropneumothorax: An Indian experience","volume":"33","author":"Kasargod","year":"2016","journal-title":"Lung India"},{"key":"R2-8-20240909","doi-asserted-by":"crossref","first-page":"280","DOI":"10.1097\/RUQ.0000000000000212","article-title":"Sonographic findings of hydropneumothorax","volume":"32","author":"Nations","year":"2016","journal-title":"Ultrasound Q"},{"key":"R3-8-20240909","doi-asserted-by":"crossref","first-page":"931","DOI":"10.1378\/chest.101.4.931","article-title":"Ultrasonographic approach to diagnosing hydropneumothorax","volume":"101","author":"Targhetta","year":"1992","journal-title":"Chest"},{"key":"R4-8-20240909","doi-asserted-by":"crossref","first-page":"10","DOI":"10.1186\/2036-7902-5-10","article-title":"Unusual new signs of pneumothorax at lung ultrasound","volume":"5","author":"Volpicelli","year":"2013","journal-title":"Crit Ultrasound J"},{"key":"R5-8-20240909","doi-asserted-by":"crossref","first-page":"246","DOI":"10.1002\/ajum.12278","article-title":"\u2019Hydro point\u2019 \u2013 The forgotten and unspoken entity in hydropneumothorax","volume":"24","author":"Mahalingam","year":"2021","journal-title":"Australas J Ultrasound Med"}],"container-title":["Turkish Journal of Emergency Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ovid.com\/10.4103\/2452-2473.342809","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,8,19]],"date-time":"2026-08-19T19:13:09Z","timestamp":1787166789000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ovid.com\/10.4103\/2452-2473.342809"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4]]},"references-count":5,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022]]}},"URL":"https:\/\/doi.org\/10.4103\/2452-2473.342809","relation":{},"ISSN":["2452-2473"],"issn-type":[{"value":"2452-2473","type":"print"}],"subject":[],"published":{"date-parts":[[2022,4]]}}}
