The most common causes of unilateral lung whiteout on chest radiograph (Fig. 45.1) are pneumonia, pleural effusion (including hemothorax), and collapse/atelectasis. The ability to differentiate between collapse and pleural effusion is essential because they require distinct treatments, which, if applied erroneously, could harm the patient [1].
