Occult pneumothorax is a condition in which a patient's clinical examination and chest radiograph are normal; but there is pneumothorax on computed tomography (CT) scan. We here describe two cases of trauma whose initial survey and chest X-ray showed normal lung markings bilaterally; but CT scan done subsequently, showed pneumothorax which was managed by chest intubation. There is still an ongoing debate about the management of occult pneumothorax. Simple observation is recommended for an asymptomatic pneumothorax. However, chest intubation is recommended for patients undergoing a surgery or mechanical ventilation due to the fear of converting a close pneumothorax into a tension pneumothorax.
