A solitary nodule is detected on a chest x-ray film in an otherwise healthy 25-year-old man. The patient has been smoking 10 cigarettes daily for 3 years. The nodule is located in the right middle lobe and measures approximately 1.5 cm. Previous chest x-ray films are not available for comparison. CT scan reveals a solitary lung nodule with a smooth contour and diffuse calcifications. No other pulmonary lesions are found. Physical examination and routine laboratory tests are normal. Which of the following is the most likely diagnosis?
(A) Aspergilloma
(B) Bronchogenic carcinoma
(C) Hemartoma
(D) Pulmonary abscess
(E) Sarcoidosis
(F) Secondary (reactivated) tuberculosis
