The blade of a knife is seen extending through the right posterior chest wall, through the body of the scapula with the tip at the outer rib edge. A right intercostal catheter is in situ, with minimal residual pneumothorax. 2 pulmonary lacerations are seen, one involving the right upper lobe, the other the posterior right lower lobe. A small to moderate haemothorax is seen, located anteriorly against the heart and in the oesophageal recess as the patient was scanned semi-prone. Subcutaneous emphysema is noted.
Fracture of the undersurface of the right fourth rib is consistent with direct blow from the knife. No further right rib fracture is identified.
The intercostal arteries are not well seen at all levels, however no evidence of a vascular injury is demonstrated. No great vessel injury. No pericardial effusion. Left lung atelectasis due to the scan position.
