Obstruction of the superior vena cava is commonly associated with the development of several collateral venous pathways. Right-to-left systemic to pulmonary venous shunting, however, rarely has been reported. This paper describes a case in which a previously unsuspected shunt, manifested by the striking visualization of myocardial and thyroid tissue in addition to other findings, was discovered on a routine lung perfusion scan. Imaging, as well as radiologic studies are presented in the investigation of this phenomenon.
