Abstract
Congenital lung malformations (CLMs) are rare developmental anomalies of the lung, including congenital pulmonary airway malformations (CPAM), bronchopulmonary sequestration, congenital lobar overinflation, bronchogenic cyst and isolated congenital bronchial atresia. CLMs occur in 4 out of 10,000 live births. Postnatal presentation ranges from an asymptomatic infant to respiratory failure. CLMs are typically diagnosed with antenatal ultrasonography and confirmed by chest CT angiography in the first few months of life. Although surgical treatment is the gold standard for symptomatic CLMs, a consensus on asymptomatic cases has not been reached. Resection, either thoracoscopically or through thoracotomy, minimizes the risk of local morbidity, including recurrent infections and pneumothorax, and avoids the risk of malignancies that have been associated with CPAM, bronchopulmonary sequestration and bronchogenic cyst. However, some surgeons suggest expectant management as the incidence of adverse outcomes, including malignancy, remains unknown. In either case, a planned follow-up and a proper transition to adult care are needed. The biological mechanisms through which some CLMs may trigger malignant transformation are under investigation. KRAS has already been confirmed to be somatically mutated in CPAM and other genetic susceptibilities linked to tumour development have been explored. By summarizing current progress in CLM diagnosis, management and molecular understanding we hope to highlight open questions that require urgent attention.

Abstract
Background Covid-19 pandemic is a major health calamity causing global crisis involving every aspect of the society. CT chest has become an essential diagnostic investigation and as a prognostic tool for assessment for COVID-19 bronchopneumonia. This case report is about an incidental unexpected finding in a young female, who underwent CT chest screening with suspicion of COVID-19 bronchopneumonia. Case presentation A 29-year-old female came with the complaints of sore throat, myalgia, and fever for the past 3 days. She was referred to our department for plain screening CT chest to rule out COVID 19 infection. She was an active sports person since childhood. CT chest revealed a large well-defined bullous cystic lesion of size 16 × 9.5 × 9.5 cm in the left lung lower lobe with partial sparing of its superior, anterior, and posterior basal segments. Imaging diagnosis of large bullous cystic lesion with emphysematous changes was made. No features of COVID 19 bronchopneumonia. Thoracoscopy-guided lobectomy was done, and tissue was sent to histopathological examination. Final diagnosis was large type 1 congenital cystic adenomatoid malformation with mucinous metaplasia. Our case is unique in the sense that large adult CCAM with mucinous metaplasia of the epithelium is a rare presentation. Further it was diagnosed as a part of COVID 19 screening. Conclusion CCAM presentation in adult is rare. Asymptomatic CCAM lesion of this size diagnosed during COVID 19 chest CT screening was rarely described.

Abstract
AbstractCongenital pulmonary airway malformation (CPAM) is a broad spectrum of congenital cystic lung lesions caused by the arrested bronchoalveolar development. Approximately, 80% of CPAMs are diagnosed prenatally or during the neonatal period when patients present with respiratory failure and cyanosis. CPAM is often associated with other organ anomalies and aplasia, and they have poor prognoses. Many CPAMs are detected in infants and school-age children, and infections like pneumonia trigger these diagnoses. It rarely manifests in adults. These often get missed because of the superadded diseases, and hence, it is essential to have a correct approach to their diagnosis to avoid misdiagnosis.

Abstract
Congenital cystic adenomatoid malformations are lung anomalies usually detected prenatally or in newborns and infants. Type 1 congenital cystic adenomatoid malformations appears as a multicystic lesion, with cysts up to 2 cm in diameter, or as a single large cyst. In the latter case, when detected in adults, the preoperative diagnosis is challenging because congenital cystic adenomatoid malformations can be confused with other more common lesions. We describe two cases of uniloculated type 1 congenital cystic adenomatoid malformation in adults. In both cases, the preoperative clinical diagnosis was missed and the patients were surgically treated with lung-sparing cyst resections.
