Fig.2: Transesophageal echocardiography at 65 degree shows the large mediastinal tumor compressing the the right ventricular outflow tract and main pulmonary artery. Doppler systolic pressure gradient across the right ventricular outflow tract was 60 mm Hg. (T = tumor mass; Rvot = right ventricular outflow tract; MPA = main pulmonary artery; AoV = aortic valve).

Fig.3a: Contrast enhanced CT showing the lobulated anterior mediastinal mass (arrow) with low attenuated area in the center. Right ventricular outflow tract is compressed by the mass (thin arrow). Inferior vena cava is normal (curved arrow). (Photo courtesy: Dr. K. Das, Radiology Dept., HMC, Doha-Qatar.)

Fig.3b: CT section bellow the carina showing the same mass with wider area of low attenuation (thick arrow). Left pulmonary artery is partly compressed by the mass. (A = Ascending aorta; LPA = left pulmonary artery; RPA = right pulmonary artery). (Photo courtesy: Dr. K. Das, Radiology Dept., HMC, Doha-Qatar.)
