Pneumothorax is defined as the presence of air in the pleural cavity. It usually occurs secondary to multiple pulmonary predisposing diseases and represents one of the most frequent forms of thoracic disease. On the other hand, primary spontaneous pneumothorax (PSP), defined as a non-underlying lung disease pneumothorax, is a less common condition, and frequently occurs in very thin, tall and young men. Its incidence goes from 5 to 9 cases per 100.000 populations per year.
Primary simultaneous bilateral spontaneous pneumothorax (PSBSP) is a very rare disease with an incidence of 1.3% of all primary pneumothorax cases. The spontaneous rupture of pleural bullae or blebs has been identified as a causal factor of primary pneumothorax. In this report we present the case of an 18-year-old male with multiple bullae who developed PSBSP.
