Correct!
3. Frontal and lateral chest radiography shows no interval change from the most recent chest radiograph (Figure 10)

Frontal and lateral chest radiography (Figure 12) shows no clear change in the 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.).

Pulmonary medicine was consulted and advised repeat unenhanced thoracic CT (Figure 13), maximizing asthma therapy, and monitoring the patient’s aortic stenosis.

Cardiology was consulted and graded the patient’s aortic stenosis as “mild-to-moderate,” and felt that the aortic stenosis was not responsible, at least entirely, for the patient’s intermittent complaints of exertional dyspnea and shortness of breath.

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

1. Thoracic CT shows development of scattered new small pulmonary miliary nodules
2. Thoracic CT shows marked progression of the anterior segment right upper lobe localized nodular opacities seen on the thoracic CT 2 months earlier (Figure 11)
3. Thoracic CT shows near complete resolution of the right upper lobe nodular opacity
4. Thoracic CT shows recurrence of the bilateral lower lobe pneumonia
5. Thoracic CT shows the right upper lobe opacity appears relatively stable or perhaps minimally improved compared to the thoracic CT 2 months earlier (Figure 11)
