Secondary Cardiac Involvement From Diffuse Large B-cell Lymphoma: A Case Report

The cardiac localization of metastases is a rare condition, most often found on autopsy. Lymphoma is among the primary cancers often involved, as was the case for our patient in whom cardiac involvements were discovered during the extension assessment by imaging. Clinically asymptomatic in the majority of cases, we mainly find general symptoms related to the primary disease. Because histological diagnosis is rarely possible by biopsy, confirmation is made by imaging in the context of disseminated disease. The treatment of cardiac involvements of lymphomatous origin is often medical with a poor prognosis.
