CT chest/abdo/pelvis.
Volume loss demonstrated in right hemithorax with mediastinal shift to right. Partial collapse of the right upper lobe, and areas of partial bilateral lower lobe atelectasis. Multiple nodular densities visualised in the right middle lobe, favoured to be pulmonary contusion.
On close examination of coronal and sagittal CT imaging, subtle contour change is noted in the left hemidiaphragm dome which is directly adjacent to the underlying stomach. This may represent a tiny defect in the diaphragm in the setting of trauma. No other intraabdominal injury or acute fractures identified.
