Thoracic CT with intravenous contrast revealed moderate pericardial and bilateral pleural effusion, mediastinal effusion, a mixed unstructured interstitial to coalescing pulmonary alveolar pattern affecting the dorsal part of the lung lobes, and moderate cranial mediastinal lymphadenopathy (2.5 cm in diameter; Figure 1).
