A condition of intrapleural air-space accumulation in individuals without any his-tory of trauma or lung disease is called as primary spontaneous pneumothorax (PSP). Sixteen-years-old male patient admitted with complains of chest pain and dyspnea beginning 3 day ago. On physical examination, severity of breath sounds decreased on right side. Chest radiograph was taken and right-sided pneumotho-rax was detected and tube thoracostomy was inserted. Two months ago the pa-tient referred to a doctor with similar complaints and physical examination and chest radiograph were reported as normal. The radiograph was retrospectively examined and bilateral PSP was detected. We presented the case duo to sponta-neous recovery of bilateral PSP is seen very rarely and so contributes data to the literature. In patients admitted to the clinic with chest pain and shortness of bre-ath, pneumothorax should be considered at differential diagnosis.
