case_images: CT chest angiogram demonstrating moderate to large-sized bilateral pleural effusions, greater on the right side (green arrowheads), moderate-sized pericardial effusion (red arrowhead), thickened pericardium (yellow arrowhead), along with mediastinal and hilar adenopathy, and mediastinal fat stranding.

case_images: The thoracic CT was negative for pulmonary embolism but revealed moderate to large pericardial effusion and small bilateral pleural effusions (Figure 1).
case_images: Photomicrograph of the pericardial biopsy. A - a low-power view of the malignant epithelioid neoplasm, highlighting the anastomosing pattern of vascular channels (H&E, 10X); B - highlights the neoplastic cells with hob-nailing, nuclear enlargement, pleomorphism, and hyperchromasia (H&E, 20X); C - highlights nuclear atypia and increase in mitotic activity of the tumor (H&E, 40X).

case_images: Abundant mitotic figures were noted throughout the neoplasm, averaging 25/10 high power fields (Figure 2).
case_images: Photomicrograph of immunohistochemistry in low-power view (magnification 10X) with tumor cells showing strong and diffuse staining for ERG (A) and CD 31 (B).
