Fig. 1 A, Esophagogram shows irregular margined-filling defect of distal esophagus from T7 level to esophagogastric junction, suggesting esophageal cancer. B, Endoscopy shows ulcerative encircling mass of distal esophagus, about 10 cm in length, suggesting esophageal cancer. C, Endoscopic biopsy from esophagus shows characteristic features of squamous cell carcinoma (hematoxylin and eosin stain, ×100).

Fig. 2 A, Parasternal short-axis view obtained by 2-dimensional echocardiography. Echocardiogram shows large mass in right ventricular outflow tract. B, Color Doppler echocardiogram. High-velocity turbulent flow indicates obstruction in right ventricular outflow tract. C, Color Doppler echocardiogram shows feeding vessel in middle of tumor (arrow). D, Pulsed Doppler echocardiogram shows diastolic dominant flow. M, tumor mass; Ao, aorta.

Fig. 3 A, T2-weighted coronal image shows large lobulated mass with intermediate signal intensity in right ventricular outflow track (RVOT) (arrowhead) and at base of right ventricle (RV). RVOT is severely stenosed. Mass is closely abutted in pericardium. Pericardial thickening is associated. B, T2-weighted coronal image shows thickened esophageal wall (arrows), suggesting esophageal carcinoma. M, tumor mass; Ao, aorta.

Fig. 4 A, Coronary angiogram of right coronary artery shows small and tortuous vessels originating from conus branch of right coronary artery (arrow), suggesting neovascular formation at site corresponding to right ventricular outflow track (RVOT). B, Lateral view of right ventriculography shows large mass occupying RVOT (arrows). C, Endomyocardial biopsy from right ventricle (RV) shows invasion of squamous cell carcinoma (hematoxylin and eosin stain, ×100). MPA, main pulmonary artery.
