Correct!
3. Frontal and lateral chest radiography shows new focal lung opacity

Frontal and lateral chest radiography (Figure 10) shows new focal lung opacity within the right upper lobe. No recurrence of the previous bilateral lower lobe pneumonias or nodules is seen, nor is there evidence of cavitation or pleural disease. No other areas of consolidation or new small scattered nodules are evident.

Thoracic CTA using a pulmonary embolism protocol (Figure 11) was again performed.

Which of the following represents the most accurate assessment of the thoracic CTA findings? (Click on the correct answer to proceed to the eleventh of nineteen pages)

1. Thoracic CTA shows bilateral pulmonary emboli with right ventricular strain
2. Thoracic CTA shows development of scattered new small pulmonary miliary nodules
3. Thoracic CTA shows new pleural thickening and loculated pleural liquid
4. Thoracic CTA shows progression of the anterior segment right upper lobe localized nodular opacities seen on the prior thoracic CTA 17 months previously
5. Thoracic CTA shows recurrence of the bilateral lower lobe pneumonia
