Note the dependent location of the small left pleural effusion in the anterior aspect of the left hemithorax (arrow). Computed tomography scan of the chest shows a soft-tissue lesion involving the right mainstem bronchus and atelectasis of the right lung with postobstructive changes in the right lower lung.omputed tomography scan of the chest demonstrates a loculated pleural effusion (E) in the left hemithorax. The loculated effusion is well defined and elliptical and similar to water in its attenuation. The less commonly seen pseudochyle (chyliform pleural effusion) can manifest as a fat-fluid or fat-calcium level.
