Diagnosis of malignant pericardial effusion during dynamic hepatic scintigraphy

Three clinically unsuspected malignant pericardial effusions were discovered during routine dynamic hepatic scintigraphy. The only common clinical feature shared by the patients was dyspnea. Static scintigrams alone would not have detected these effusions, which points out again the importance of including dynamic scintigraphy in routine radionuclide evaluations of the liver.
