title: Intracavitary metastatic non-Hodgkin's lymphoma simulating an atrial myxoma.
abstract: We describe a case of intracavitary metastasis of Mantle Cell Lymphoma of gastrointestinal tract, which mimicked an atrial myxoma. The gastrointestinal lymphoma led to widespread metastasis and a large metastatic tumor deposit at the hilum of the right lung caught up the hilar vessels. This led to infiltration into the pulmonary veins and intracavitary metastatis to the left side of the heart.
