[Spontaneous hemothorax: a rare but serious complication of intralobular pulmonary sequestration].

Pulmonary sequestration is a rare congenital malformation characterized by a non-functional portion of pulmonary parenchyma devoid of any connection with the bronchial tree and pulmonary artery. If not identified antenatally or at birth, the sequestration may not be discovered until complications, mainly repeated infections, arise. Hemorrhage is another but much rarer complication which is generally severe. We report a new case of intralobular pulmonary sequestration revealed by hemoptysis then massive hemothroax with shock requiring emergency thoracotomy for hemostasis.
