Chest radiography revealed mild widening of the cardiac silhouette and right pleural effusion (Figure 1).
Contrast computed tomography (CT) scan on the next day of hospitalization. Right internal mammary artery (IMA) is divided into branches. A red arrow shows main branch of IMA and a yellow arrow shows the extravasation at a branch of IMA. There is small anterior mediastinal hematoma (red arrowheads) around the extravasation. Massive bloody pleural effusion is confirmed in the right lung.
