There is a right sided ICC which appears to traverse the lung parenchyma of the right lower lobe, tip projected towards the apex. A large haemothorax. Small anterior right pneumothorax in the anterior base.
The stab wound appears in the right parasternal region where there is a small irregularity in the skin and a small amount of gas adjacent to the right mediastinum between the right third and fourth ribs anteriorly. Internal thoracic artery on the right appears intact although there is no delayed imaging.
No haemopericardium and the left lung is clear. Aorta and mediastinal structures appear intact.
Conclusion
Right haemothorax and right small pneumothorax (haemopneumothorax). The right chest tube appears to transverse the lung parenchyma and may cause some of the changes noted in the right lower lobe (not at the site of the stab wound). No specific damage to the mediastinal structures.
