CTICasesTraumatic Cough-Induced Lung Herniation
Imaging findings
Chest CT shows herniation of lung parenchyma through the chest wall (transcostal herniation). There is a tear in the intercostal muscles and an acute rib fracture, arising after a single episode of severe coughing.
Key takeaways
Severe coughing can generate sufficient intrathoracic pressure to fracture ribs, tear intercostal muscles, and cause acute lung herniation through the chest wall, requiring surgical reduction and repair.
