CT and MR findings of primary cardiac lymphoma: report upon 2 cases and review.

ABSTRACT

Although primary cardiac lymphoma was a near fatal disease in the past, recent advances in imaging diagnosis and chemotherapy have dramatically improved survival. We describe the CT and MR findings of primary cardiac lymphoma in two immunocompetent subjects who recovered after chemotherapy. The primary cardiac lymphomas manifested as a poorly enhancing mass on CT, relatively hyperintense on a T2-weighted image and a heterogeneously enhanced mass on contrast-enhanced MR. The tumor also showed a predilection for right heart chambers and contiguous infiltration along adjacent structures.
