Pulmonary Hematoma
Epidemiology
Physiology
- Traumatic hemorrhage into lung
- May result from external trauma or secondary to surgical wedge/ segmental lung resection
- Presence of hematoma may be masked by surrounding lung contusion
Diagnosis
- CXR/Chest CT Pattern: oval/ round sharply-defined, smooth nodule (may be multiple)
- Location: usually a peripheral, subpleural location
- Calcification: none
- Cavitation: air-fluid level may be seen (due to parenchymal laceration of traumatic lung cyst)
Treatment
- Decrease in size over time (may persist for up to 4 months)
