3. Enhanced chest CT shows a relatively non-specific right pleural effusion

Contrast-enhanced chest CT shows a homogeneous right pleural effusion; trace smooth right pleural thickening may be present, but no nodularity is evident. There is no evidence of pneumothorax. Right middle and lower lobe passive atelectasis is also present, but no left pleural effusion or significant intrathoracic lymph node enlargement is evident. Some mild subpleural reticulation bilaterally is present, with mild linear abnormality and architectural distortion in the left upper lobe where borderline bronchial dilation is evident.

Which of the following represents an accurate statement regarding the chest CT findings? (Click on the correct answer to be directed to the fifth of seventeen pages)

1. The absence of pleural thickening excludes the possibility of an exudate
2. The presence of pleural thickening excludes the possibility of a transudative pleural effusion
3. The use of intravenous contrast is required for the detection of pleural thickening
4. The presence of pleural thickening predicts the presence of an exudative effusion
5. The lack of visible pleural nodularity excludes the possibility of pleural space malignancy
