Bone lymphoma presenting as an intra-atrial mass proves fatal despite palliative chemotherapy.
Case Report (n=1)
No
This case report highlights a rare instance of non-Hodgkin's lymphoma with intracavitary cardiac involvement, emphasizing the role of echocardiography in detecting such lesions.
Echocardiography may detect rare intracavitary lymphoma extension; this Level 5 case leaves management questions open.
An 84-year-old man with non-Hodgkin's malignant lymphoma presented with a pathological fracture of the femur and also an intra-atrial mass on echocardiography. The patient was given palliative low-dose chemotherapy, but died of tumor dissemination, hypercalcemia, and dehydration. Autopsy revealed diffuse large B-cell lymphoma involving multiple bones and lymph nodes (the latter were not detected during staging), and a solitary mass on the posterior wall of the right atrium. This rare lesion appeared to be due to hematogenous spread, since the myocardium and pericardium were free of tumor infiltration. A literature review indicated that the frequency of cardiac involvement differed between contemporary and earlier reports, mainly due to the availability of increasingly sophisticated diagnostic methods and improvements in chemotherapy.

Satō et al. (1993) conducted a case report in Non-Hodgkin's malignant lymphoma of the bone with intracavitary cardiac involvement (n=1). Palliative low-dose chemotherapy was evaluated. An 84-year-old man with non-Hodgkin's malignant lymphoma of the bone presented with an intra-atrial mass and died of tumor dissemination despite palliative chemotherapy.
