Afr. j. radiol."],"abstract":"<jats:p>Pulmonary underdevelopment is a rare congenital disease which manifests as persistent hemithorax opacification at chest radiography. We present three patients with different types of pulmonary underdevelopment, their imaging features and associated anomalies. Case 1 is a premature neonate with persistent respiratory distress. Further imaging confirmed right pulmonary hypoplasia, associated with a patent foramen ovale, patent ductus arteriosus and vertebral anomalies. Case 2 is a 6-year-old child with corrected anorectal malformation, and recurrent pneumonia. Further imaging confirmed left pulmonary aplasia, associated with an aberrant right subclavian artery and vertebral anomaly. Case 3 is a full term neonate who developed excessive drooling of saliva and respiratory distress. Further imaging confirmed right pulmonary agenesis, associated with an atrial septal defect, patent ductus arteriosus and tracheo-oesophageal fistula. Pulmonary underdevelopment is classified into three types: hypoplasia, aplasia and agenesis. The majority of them have associated anomalies. This condition should be considered a differential diagnosis in paediatric patients with an opaque hemithorax on chest radiography.<\/jats:p>","DOI":"10.4102\/sajr.v25i1.2164","type":"journal-article","created":{"date-parts":[[2021,9,1]],"date-time":"2021-09-01T03:13:26Z","timestamp":1630466006000},"source":"Crossref","is-referenced-by-count":1,"title":["Unilateral opaque chest radiograph in paediatrics: A case series"],"prefix":"10.4102","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9331-5831","authenticated-orcid":false,"given":"Tengku A.","family":"Raja Mamat","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1976-9568","authenticated-orcid":false,"given":"Khairil A.","family":"Sayuti","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4165-2625","authenticated-orcid":false,"given":"Chandran","family":"Nadarajan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0919-4609","authenticated-orcid":false,"given":"Mohd R.","family":"Mohd Zain","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2580","published-online":{"date-parts":[[2021,8,31]]},"container-title":["South African Journal of Radiology"],"original-title":[],"link":[{"URL":"https:\/\/sajr.org.za\/index.php\/sajr\/article\/viewFile\/2164\/2986","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/sajr.org.za\/index.php\/sajr\/article\/viewFile\/2164\/2987","content-type":"application\/epub+zip","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/sajr.org.za\/index.php\/sajr\/article\/viewFile\/2164\/2988","content-type":"text\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/sajr.org.za\/index.php\/sajr\/article\/viewFile\/2164\/2989","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/sajr.org.za\/index.php\/sajr\/article\/viewFile\/2164\/2989","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,9,1]],"date-time":"2021-09-01T03:13:26Z","timestamp":1630466006000},"score":1,"resource":{"primary":{"URL":"https:\/\/sajr.org.za\/index.php\/sajr\/article\/view\/2164"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,8,31]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2021,1,15]]}},"URL":"https:\/\/doi.org\/10.4102\/sajr.v25i1.2164","relation":{},"ISSN":["2078-6778","1027-202X"],"issn-type":[{"type":"electronic","value":"2078-6778"},{"type":"print","value":"1027-202X"}],"subject":[],"published":{"date-parts":[[2021,8,31]]}}}
