Abstract
Chest trauma and its complications are
responsible for about 25% of deaths dueto blunt trauma. Lung contusion is a common complication of blunt chest trauma as it happens in 30 to 75% of the cases. As a result of chest trauma, there is direct or indirect damage of the parenchyma of the lung that leads to edema or alveolar hematoma and loss of physiological structure and function of the lung. Chest Computed Tomography (CT) scan is more sensitive than CXR and is considered as the gold standard technique for detecting lung contusion Chest CT scan reveals the exact distribution and size of pulmonary injury. A higher resolution of CT scans can detect contusion immediately after
trauma. Contusion volume on a three dimensional reconstruction from chest CT can help identify patients at higher risk of ARDS. Patients with severe pulmonary contusion (contusion volume equal to or greater than 20%) are at
higher risk of developing ARDS and pneumonia, as compared to moderate pulmonary contusion (contusion volume less than 20%
