PathWays Case Study: Feb. 7

A 43-year-old male presented with recurrent bilateral pneumothoraces (6 on the right, 3 on the left) within the past year. Chest X-ray revealed diffuse cystic abnormalities with interstitial changes predominantly in the mid and upper lungs. CT images of the chest (Figure 1) showed diffuse cystic changes with upper lobe predominance and relative sparing of the lung bases. The patient underwent wedge resection of the superior segment of the right lower lobe.
