Congenital lobar emphysema (CLE) is caused by airway defects resulting in air trapping and hyperinflation of the affected lobe. Case reports of families affected with CLE imply a genetic etiology. However, the genetic contributions have not been well-described. We present a case of CLE in a monozygotic twin brother with respiratory distress diagnosed with right upper lobe (RUL) CLE and treated with a lobectomy. His asymptomatic twin brother was screened prophylactically, found to have RUL CLE and subsequently underwent a lobectomy. Our report provides further evidence supporting the genetic predisposition and potential benefit of early screening for CLE in comparable scenarios.
先天性大叶性肺气肿（CLE）由气道缺陷引起，导致患叶气体潴留和过度充气。CLE患者家族的病例报告提示其存在遗传病因。然而，遗传因素的作用尚未得到充分描述。我们报告一例患有呼吸窘迫的单卵双胞胎兄弟，诊断为右上叶（RUL）CLE并接受了肺叶切除术。对其无症状的双胞胎兄弟进行了预防性筛查，发现患有RUL CLE，随后也接受了肺叶切除术。我们的报告提供了进一步的证据，支持在类似情况下CLE的遗传易感性以及早期筛查的潜在益处。
