title: Radiological appearance of diaphragmatic mesothelial cysts.
abstract: BACKGROUND
  Diaphragmatic mesothelial cysts are congenital lesions that derive from coelomic remnants.
  
  
  OBJECTIVE
  To describe their radiological appearance on US, CT and MRI.
  
  
  METHODS
  Four children (aged 7-14 years) who underwent surgery and for whom there was pathological confirmation of the diagnosis. Five more children (0-12 months old) who were managed conservatively, but for whom there was a high degree of suspicion for this diagnosis.
  
  
  RESULTS
  All lesions presented as a cystic mass between the thoracic wall and the liver, in the right posterolateral costophrenic angle. Some lesions showed subtle evidence of their extrahepatic location.
  
  
  CONCLUSIONS
  The radiological findings identified are highly suggestive of diaphragmatic mesothelial cyst.
