(A) Tachycardia in electrocardiogram at admission. (B) The mass in the contrast-enhanced CT. The size was 46 x 42 mm and serious adhesion between the aorta and the mass was found. Also, the involved left main coronary was observed. (C) The mass in the MRI. Both the root of the aorta and left main coronary were involved, however, the myocardium was free from involvement. (D) The mass in the echocardiography. The mass was fully perfused through mini-vascular circulation. (E) The repairing of the pulmonary artery. (F) The removed mass.

When at admission, tachycardia was found by electrocardiogram (Figure 1A). Based on the findings from the contrast-enhanced CT, it was demonstrated that a mass of 46 x 42 mm with serious adhesion to the surrounding aorta located at the root of the aorta in the middle mediastinum and the left main coronary was also involved (Figure 1B). In MRI, it was confirmed that both the root of the aorta and left main coronary were involved, however, the myocardium was free from involvement (Figure 1C). In accordance with the echocardiography, the mass was completely perfused through mini-vascular circulation (Figure 1D). After the mass was removed completely, a bovine pericardial patch of reasonable size was used to repair the pulmonary artery (Figures 1E,F).
(A) Pathology of the removed mass. The pathological findings of the mass were confirmed as cardiac paraganglioma. (B) The echocardiography at the latest follow-up. Morphologically, all the chambers and valves were normal and the heart function was stable without any serious abnormal changes. (C) Sinus rhythm in electrocardiogram rechecking. (D) Coronary CT angiography shows a patent coronary vessel.

Pathologically, the removed mass was confirmed as cardiac paraganglioma (Figure 2A). During the latest follow-up, it was shown that, morphologically, all chambers and valves were normal and the heart function was stable without any serious abnormal changes (Figure 2B). The sinus rhythm was found by electrocardiogram rechecking (Figure 2C). Furthermore, it was demonstrated via the coronary angiography, the patency of grafts for both LIMA-LAD and AO-SVG-LCX was qualified without any obstructions (Figure 2D).
