Pseudo-pneumothorax occurs after inappropriately diagnosing a pneumothorax based on a chest X-ray. This can be attributed to skin folds, bed sheets, previous pneumothorax, heating blankets, clothes, and other circumstances that may mimic the radiographic findings of a pneumothorax. We present a case where a patient underwent a tube thoracostomy due to the diagnosis of a pneumothorax that was not, in fact, present. The unnecessary intervention was complicated by hemoptysis and cardiac arrest.
