CT scan performed without intravenous injection of contrast material shows heterogeneous opacification of the right hemithorax with mostly higher attenuation material. A right-sided chest tube is in place. Cardiomediastinal shift to the left is seen. The interventricular cardiac septum is seen as a higher attenuation structure when compared to the interventricular blood. This suggests a severe dilutional anemia due to severe hemorrhage with a hemoglobin level of less than 7 g/dL.
