Pulmonary Laceration

Traumatic Lung Cyst

Pulmonary Hematoma

Usually not apparent at first because of surrounding pulmonary contusion
Half are solid mass-like lesions (pulmonary hematoma), half are thin-walled cystic structures (traumatic lung cyst) with or without air- fluid level — depends on how much bleeding into laceration
Usually subpleural location under point of maximum impact
May be single or multiple
Characteristically, they take a long time to heal – many months. They gradually decrease in size.
No symptoms from laceration per se unless they become infected, which is rare.
