Non contrast CT axial, coronal and sagittal images show biconvex haematoma, which displaces the parietal pleural and the extrapleural fat.
In addition multiple rib fractures are seen.
Case Discussion
Extrapleural haematoma is usually caused by trauma. It is produced by rupture of intercostal or internal mammary vessels. There is no interruption of the parietal pleura, which allows blood to stay in the extrapleural space. It is usually associated with rib fractures.
The observed very thin hypodense line representing the parietal pleura is a helpful imaging feature of these extrapleural collections.
