CT appearance of the pleural space after talc pleurodesis.

Objective: This study describes the CT appearance of the pleural space after talc pleurodesis.

Conclusions: After talc pleurodesis, the pleural space reveals variable degrees of pleural thickening and nodularity, often with a residual loculated effusion. High-attenuation areas representing talc deposits are expected and should not be confused with other pleural abnormalities.
