A rare case of direct tumor extension to the right ventricle

Abstract

We report the case of a 72-year-old woman with signs of pulmonary embolism and right heart failure. Echocardiographic imaging and computed tomography revealed a mass within the inferior vena cava reaching from the head of the pancreas to the right ventricle. From standard imaging procedures and clinical findings alone, differentiation of a cardiac thrombus from a metastatic tumor mass was difficult. After resection of the intravascular tumor, histopathologic analysis confirmed a metastasis of primary ductal pancreatic adenocarcinoma. This is a report of a case of mucinous adenocarcinoma of the pancreas reaching the heart by continuous intravascular spreading.
