AI Article Synopsis
- - A 38-year-old woman experienced cough and fever, leading to a chest X-ray that showed an abnormal shadow in her left lung.
- - High levels of the carbohydrate antigen 19-9 (CA19-9) were found in her blood, indicating a medical issue, which was confirmed by surgery revealing intralobar pulmonary sequestration.
- - After removing the affected lung lobe, her CA19-9 levels returned to normal, marking a significant find as this is the first reported case of elevated CA19-9 associated with pulmonary sequestration.
Article Abstract
A 38-year-old female presented with cough and fever. A chest X-ray examination revealed an abnormal shadow in the posteroinferior portion of the left hemithorax, and a laboratory examination showed that the serum carbohydrate antigen 19-9 (CA19-9) level was markedly high (1000 U/ml). A left thoracotomy showed an intralobar pulmonary sequestration of the left lower lobe, and after a left lower lobe lobectomy, the serum level of CA19-9 decreased to normal. Increased CA19-9 activity was detected by immunohistochemistry in the epithelia of bronchioles in the pulmonary sequestration. This communication is the first to report a case of increased activity of CA19-9 in pulmonary sequestration.

Bronchopulmonary sequestration is an uncommon abnormality of the respiratory system that often manifests as recurrent pneumonia in childhood or as an incidental discovery on thoracic imaging in adults. The sequestration receives its blood supply from anomalous systemic circulation in contrast to pulmonary circulation and can manifest in either intrapulmonary or extrapulmonary forms. We discuss the instance of a young asymptomatic man who visited us seeking for medical clearance to travel abroad.

Extensive congenital pulmonary airway malformation (CPAM) of the left fetal lung and associated marked dextroposition of the fetal heart were noted at 21 weeks' gestation. The right fetal lung appeared compressed with the cardiomediastinal shift angle measuring approximately 20 degrees. Potential subsequent right pulmonary hypoplasia was considered.

Introduction: In this single-center retrospective analysis, we present case data and insights gathered over the past eight years. Additionally, we computed postnatal, pre-therapy lesion-to-lung ratios of Congenital Pulmonary Airway Malformations (CPAMs) to retrospectively assess potential outcome prediction using lesion-to-lung ratios.
Methods: Data were collected between 2015 and 2022.

Pulmonary sequestration (PS) is a rare congenital malformation that is characterized by the absence of a connection between a portion of the lung tissue and the tracheobronchial tree, with blood supply from arteries throughout the body. Abnormal lung tissue cannot perform the normal gas exchange function. In the absence of timely diagnosis and early intervention, some cases may need labor induction, and some of the infants who survive may develop symptoms in childhood.
