2. The frontal chest radiograph is non-specifically abnormal

The frontal chest radiograph shows some potential abnormalities, and therefore is not completely normal, but the findings are minor and non-specific. The chest radiography shows some increased opacity in the medial right apex, which may reflect thyroid enlargement or tortuous vascularity. Faint nodular opacity is present in the medial right base, although clear evidence of a mass is not seen. A clear, active cardiopulmonary process is not readily identifiable. A small nodular [“miliary”] pattern is not present. No “hard” features of significant volume loss- such as fissure displacement, bronchial displacement, rib narrowing, etc. are seen. Features of a diffuse fibrotic process such as architectural distortion, coarse reticulation, honeycombing, and clear traction bronchiectasis are not present.

Clinical Course: The patient subsequently underwent thoracic CT (Figure 2).

Regarding the thoracic CT, which of the following statements is most accurate?

1. The thoracic CT findings are most suggestive of an active, non-infectious alveolitis
2. The thoracic CT findings suggest a diffuse fibrotic lung disease
3. The thoracic CT findings suggest a process primarily producing airway obstruction
4. The thoracic CT findings suggest an active, diffuse pulmonary infection
5. The thoracic CT findings are most suggestive of multifocal pulmonary hemorrhage
