title: [Isolated bilateral pulmonary occlusion].
abstract: BACKGROUND
  Takayasu's arteritis (TA) is an unusual cause of bilateral and isolated pulmonary artery occlusion that may be difficult to distinguish from other aetiologies.
  
  
  OBJECTIVE
  Report a new case of isolated bilateral pulmonary occlusion.
  
  
  METHODS
  A 19 year-old girl presented to the hospital with a 2-year history of dyspnoea and recurrent hemoptysis. She was in respiratory distress on physical examination Clinical investigations revealed a total occlusion of the right pulmonary artery on perfusion lung scan. Pulmonary angiogrphy confirmed these data and revealed further more a partially occluded left lower lobe artery. Diagnosis of Takayasu's arteritis was suspected and a complete aortogram was made but proved to be normal. Corticosteroid therapy was prescribed but interrupted within 2 months for absence of clinical improvement. Patient's assessment revealed worsening of the clinical condition and she became oxygen-dependant.
  
  
  CONCLUSIONS
  early diagnosis of isolated involvement of pulmonary arteries in TA while systemic arteries are normal may prove to be difficult. In spite of insufficient data to confirm TA, the latter seems to be the most probable diagnosis in our patient regarding clinical (young age) and angiographic arguments.
