Patients with a spontaneous pneumothorax frequently present for care in the emergency department. The occurrence of spontaneous pneumothorax during parturition occurs rarely. We describe a case of spontaneous pneumothorax during the first trimester of pregnancy, which resolved with tube thoracostomy. The patient delivered vaginally a healthy 4.3 kg male at term under epidural anesthesia. We discuss spontaneous pneumothorax and review reported cases during pregnancy.
