MCQ Radiology Answer 25

The correct answer is A.

This is a classic presentation of a pulmonary abscess. Chronic courses with less severe symptoms (with intermittent improvement following short courses of antibiotics) are also sometimes seen, particularly if the diagnosis was not suspected. Chest x-ray typically shows pneumonic opacification in which a cavity, often with a fluid level, is visible. Pulmonic abscesses can be caused by anaerobes (most common, particularly if aspiration initiated the abscess), gram-negative aerobic bacilli, and Staphylococci. Therapy is based on the organisms isolated, and should be continued for at least 4 to 6 weeks. In cases that fail to resolve, the possibility of coexisting carcinoma should be considered.
Choice B is the x-ray appearance of pleural effusion.
Choice C is the x-ray appearance of lobar pneumonia.
Choice D is the x-ray appearance of bronchopneumonia.
Choice E is the x-ray appearance of bronchiectasis.
