CTICasesCombined Partial Anomalous Pulmonary Venous Return and Congenital Bronchial Atresia

Imaging findings
CT pulmonary angiogram revealed partial anomalous pulmonary venous return from the right upper lobe draining into the superior vena cava and right atrium. Concurrently, there was an area of air trapping with extra-parenchymal branching structures tucked medially in the upper lobe, which did not connect to any obvious bronchus and tapered into the mediastinum, consistent with congenital bronchial atresia and an associated bronchocele. No atrial septal defect or pulmonary hypertension was evident.
Key takeaways
This is a rare and likely unreported combination of partial anomalous pulmonary venous return and congenital bronchial atresia in the same patient. The case highlights the concept of related embryological developmental disturbances leading to multiple congenital abnormalities. It underscores the importance of thorough evaluation in patients with chronic, unexplained respiratory symptoms, as this gentleman's condition remained undiagnosed for 20 years.
