Findings

There is a moderate pleural effusion with rounding and retraction of the lung lobes. There is increased opacity of the right middle lobe with subtle radiolucent stippling. The lung lobe is enlarged with convex borders, seen best on the v/d projection. The bronchus to the right middle lung lobe appears to be in a normal postition, although it is not air filled along its entire length.

On the CT image, the emphysema within the right middle lung lobe and its increased size are more visible. The bronchus to the right middle lobe narrows and opens again distal to the carina (axial and 3-D images).
