title: [Horseshoe lung with normal pulmonary venous return].
abstract: BACKGROUND
  Horseshoe lung is a rare congenital anomaly characterised by a midline isthmus of pulmonary parenchyma connecting the posterior basal segments of the lungs behind the heart in conjunction with unilateral pulmonary hypoplasia. Of all cases, 80% are associated with scimitar syndrome, consisting of right anomalous pulmonary venous drainage, pulmonary hypoplasia of the right lung and systemic arterial perfusion to some lung areas.
  
  
  METHODS
  A six year old girl who had recurrent lower respiratory infections since birth. Chest Rx, angioCT and MR showed: hypoplasia of the right lung, dextrocardia and pulmonary isthmus bridging both lungs behind the pericardium. The right hypoplastic lung had little systemic supply coming from the abdominal aorta. The right pulmonary artery was hypoplastic. The right pulmonary venous drainage was normal.
  
  
  CONCLUSIONS
  We present a case of horseshoe lung without abnormal venous drainage.
