3. Re-expansion pulmonary edema
The M-modes in panels A and B show a normal "seashore" sign and not the "barcode" sign seen with a pneumothorax. Furthermore, there is lung sliding on both sides suggesting that a large pneumothorax is unlikely. The ultrasound shows "b" lines in the right lung in panel D. These are vertical lines radiating to the edge of the image. "b" lines have been associated with interstitial edema. There are either no or few "b" lines in panel C. Given the clinical situation, the best explanation is unilateral pulmonary edema associated with re-expansion pulmonary edema. Although re-expansion pulmonary edema is more likely to occur with removal of pleural fluid of >1500 ml, it can occur with removal of smaller volumes.
