Clinical History: A 79-year-old man with a past medical history significant for mild, intermittent asthma since childhood and mild aortic stenosis presents to the Emergency Room with fevers and chills for 5 days, associated with dry cough and dyspnea on exertion. His past medical history was otherwise relatively unremarkable, with coronary artery disease as evidenced by coronary artery calcium at a calcium scoring CT, hypothyroidism, and dyslipidemia. The patient has allergies to dust and penicillin, and his only medications included thyroid replacement, aspirin, and an albuterol inhaler as needed. He was a 15-pack-year smoker, quitting 30 years ago. His past surgical history was remarkable only for tonsillectomy, inguinal hernia repair, meniscal repair, and sigmoid colon resection for diverticular abscess 14 years earlier. The patient was afebrile, his heart rate was 96 beats / minute and regular, decreased breath sounds at the lung bases was noted, and the white blood cell count was normal. Electrocardiography showed no abnormalities. Oxygen saturation was 92% on room air. Frontal chest radiography (Figures 1A and B) was performed.

Figure 1. Frontal (A) and lateral (B) chest radiography.

Which of the following represents the most accurate assessment of the frontal chest imaging findings? (Click on the correct answer to proceed to the second of nineteen pages)

  1. Chest frontal imaging shows bilateral pleural fluid collections
  2. Chest radiography shows bilateral lower lobe bronchial wall thickening and patchy consolidation
  3. Chest radiography shows cavitary lung disease
  4. Chest radiography shows numerous small nodules
  5. Chest radiography shows peribronchial and mediastinal lymphadenopathy
