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.
虽然原发性心脏淋巴瘤在过去是一种近乎致命的疾病，但近年来成像诊断和化疗方面的进展显著提高了生存率。我们描述了两名免疫功能正常的患者在化疗后康复的原发性心脏淋巴瘤的CT和MR表现。原发性心脏淋巴瘤在CT上表现为强化不佳的肿块，在T2加权图像上相对高信号，在对比增强MR上为不均匀强化的肿块。肿瘤还表现出对右心腔的偏好以及沿相邻结构的连续性浸润。
