Extensive subcutaneous emphysema present, limiting lung evaluation. Marked hyperinflation of lungs consistent with underlying emphysema. Progression of focal airspace opacity in the left upper to mid lung, concerning for evolving pneumonia. Interval decrease in elliptical opacity in the right mid lung near the chest tube, likely representing loculated fluid within the horizontal fissure. No pneumothorax appreciated. Cardiac and mediastinal contours appear stable.
