These two congenital lesions are areas of aberrant lung parenchyma not connected to the central airways. Their main difference is the arterial supply. That's why the first thing to do is try to identify the systemic artery that supplies the lesion 🟣(most often an aortic branch)
This intralobar pulmonary sequestration was infected that's why it has
🟡🔵 Air-fluid levels inside
🟢 Peripheral GGO

🟢 Regional Lymphadenopathies
Many of you suggested adenocarcinoma as a differential diagnosis which could be possible but in this case you also see extrapleural fat hypertrophy 🟡 which is often encountered in chronic Benign pathologies
