CTICasesMechanical lung injury
Imaging findings
Chest radiograph and CT in a right lung transplant recipient show an elongated, loculated-appearing cystic space containing dense debris (representing hemorrhage) in the right middle lobe, located directly adjacent to a thoracotomy defect with a sharp step-off of a spread rib.
Key takeaways
Mechanical lung injury can occur post-thoracotomy due to repetitive friction between the lung parenchyma and sharp, step-off edges of spread ribs. This presents as a focal cavitary or cystic lesion with adjacent hemorrhage at the thoracotomy margin.
