1. The frontal chest radiograph shows a large right pleural effusion
The frontal chest radiograph shows homogeneous opacity in the inferior and lateral right thorax with a meniscoid shape characteristic of pleural effusion; the pleural fluid collection appears large. There is no evidence of either pneumothorax or pneumomediastinum. The mediastinal contours, as far as they can be visualized, appear normal. The left lung and right upper lobe remain clear- no evidence of developing diffuse alveolar damage is present.
Clinical Course: Following the percutaneous microwave ablation procedure, the patient developed acute renal failure (serum creatinine increased from 1.9 mg/dL at baseline to a peak of 4.5 mg/dL), as well as a drop in hemoglobin (from 13.1 mg/dl at baseline to a low of 10 mg/dL).
