Chest Radiographs during the first admission. Panel A shows the chest X-ray on presentation. There is an inhomogeneous opacification with soft tissue infiltrates noted in the right basal lung. There is also soft tissue opacification and haziness in the left lung lower zone. Both costophrenic angles appear hazy. Panel B shows the X-ray after a week of antibiotic therapy. There is interval increase in homogenous haze representing air space shadowing in the right lower lung zone. Right costophrenic angle is intervally more blunt. Panel C shows the chest x ray after a week of corticosteroid therapy. There is interval resolution of right lower lobe opacity. The rest of the findings are unchanged.
