Unilateral PA is often associated with other congenital anomalies, whereas bilateral PA is fatal. Prenatal diagnosis is rare and is diagnosed more frequently in the postnatal period than in the prenatal period. Is a challenge that may be difficult as it shares similar features with other more common pathologies. Ultrasound plays a crucial role in early diagnosis and management. Ultrasonographic findings for a correct prenatal diagnosis include mediastinum displacement with the absence of parenchymal or cystic tissue, decreased thoracic volume, an elevated diaphragm, cardiac axis deviation, and a hemithoracic cavity largely occupied by the heart. Cases of right PA have a worse prognosis compared to left PA, probably due to higher frequency of cardiac and great vessel abnormalities. A rare case of early prenatal ultrasound diagnosis of unilateral fetal PA, at 18 weeks of gestation, is reported.<\/jats:p>","DOI":"10.4103\/jmu.jmu_24_23","type":"journal-article","created":{"date-parts":[[2023,11,8]],"date-time":"2023-11-08T05:00:25Z","timestamp":1699419625000},"page":"259-261","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Prenatal Ultrasound Diagnosis of Unilateral Pulmonary Agenesis"],"prefix":"10.4103","volume":"32","author":[{"given":"Eduardo","family":"Reyna-Villasmil","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Obstetrics and Gynecology Service, Hospital Central \u201cDr. Urquinaona\u201d, Maracaibo, Venezuela"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liliana","family":"Brice\u00f1o-Sanabria","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Bayview Surgery Center, Sarasota, Florida, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juan Carlos","family":"Brice\u00f1o-Sanabria","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Hospital San Juan De Dios, R\u00edonegro, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos","family":"Brice\u00f1o-P\u00e9rez","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Zulia, Maracaibo, Venezuela"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2023,11,3]]},"reference":[{"key":"R1-20240830","doi-asserted-by":"crossref","first-page":"335","DOI":"10.1097\/OGX.0000000000000070","article-title":"Isolated unilateral pulmonary agenesis and other fetal thoracic anomalies","volume":"69","author":"Russell","year":"2014","journal-title":"Obstet Gynecol Surv"},{"key":"R2-20240830","doi-asserted-by":"crossref","first-page":"2017","DOI":"10.7863\/jum.2012.31.12.2017","article-title":"Prenatal diagnosis of isolated right lung agenesis using ultrasound alone: Case study and systematic review of the literature","volume":"31","author":"Meller","year":"2012","journal-title":"J Ultrasound Med"},{"key":"R4-20240830","doi-asserted-by":"crossref","first-page":"157","DOI":"10.1007\/s10396-012-0410-7","article-title":"Usefulness of ultrasonography and MRI for diagnosis of fetal pulmonary agenesis: Case report and review of the literature","volume":"40","author":"Ito","year":"2013","journal-title":"J Med Ultrason (2001)"},{"key":"R5-20240830","first-page":"103","article-title":"Agenesis of the lung","volume":"87","author":"Brunner","year":"1963","journal-title":"Am Rev Respir Dis"},{"key":"R6-20240830","first-page":"38","article-title":"Pulmonary agenesis: A case report with review of literature","author":"Khurram","year":"2013","journal-title":"Qatar Med J 2013"},{"key":"R7-20240830","doi-asserted-by":"crossref","first-page":"175","DOI":"10.1542\/peds.42.1.175","article-title":"Agenesis of the lung.
