Diagnosis and treatment of Primary Cardiac Lymphoma: A Case Report

Abstract

Background: Primary cardiac lymphoma (PCL) is an extremely rare cardiac tumor and progresses rapidly, which often has short median survival time and poor prognosis unless diagnosed and treated in time.Case presentation: A 61-year-old man was admitted to hospital with repeated chest tightness and pain for 3 days and the right atrial mass by ultrasonography in the other hospital for 1 day. The echocardiography revealed an irregular hyperechoic mass in the right atrium with the size of the mass is about 5.3cm*4.3cm. Partial resection of right atrial tumor under general anesthesia and cardiopulmonary bypass was performed. After operation, enhanced chest computed tomography (CT) showed a mild enhancement mass in the right atrium. The histopathological examination revealed diffuse large B cell lymphoma. After careful examination, PCL was diagnosed and chemotherapy of low dose R-CHOP for 6 courses were used. After the last course, enhanced CT examination showed that the tumor almost disappeared and the patient's symptoms improved significantly.Conclusion: PCL is a extraordinarily rare disease with poor prognosis, and it is necessary to improve the awareness of this disease.Prompt diagnosis and timely chemotherapy in combination with surgery could lead to excellent clinical outcomes of the patient with PCL.
