Lung abscess with subcutaneous emphysema, pneumothorax and pneumopericardium
A diagnosis of lung abscess was made on chest x-ray. A large bore intercostal drainage tube was inserted. During the procedure the tube migrated a little which was then re-positioned. Following this there was visible subcutaneous air accumulation and the patient became tachypneic. The patient was stabilized and CT scan was performed which showed surgical emphysema, pneumothorax and pneumopericardium.
