Pseudo-pulmonic stenosis in non-Hodgkin's large B-cell lymphoma

There have only been a few cases reported of right ventricular outflow tract obstruction secondary to diffuse large B-cell lymphomas. Mediastinal masses rarely cause extrinsic compression of the heart resulting in hemodynamically significant obstruction. We report a rare case of right ventricular outflow tract obstruction secondary to diffuse large B-cell lymphomas. Echocardiography has been found to be a useful modality in the prompt identification of mediastinal masses and their effects on the otherwise healthy heart.
