Pleural effusions

  • This patient with left ventricular failure has developed pleural effusions
  • Note that the heart is enlarged and the upper zone vessels appear prominent – if these features are absent then other causes of pleural effusions become more likely

Asymmetric pleural effusions

  • Pleural effusions caused by heart failure may not be symmetrical
  • This patient with heart failure had been nursed lying on their right side before this X-ray was taken
  • Fluid has accumulated in the right pleural space – the right costophrenic angle is not visible
  • No effusion is present in the left pleural space – the left costophrenic angle remains visible
  • The left heart border is not distinct because there is pulmonary oedema of the adjacent lung
