An Atypical Presentation of Hodgkin Lymphoma Invading the Myocardium.

Pericardial involvement by Hodgkin lymphoma has been found in up to 20% of children at presentation, but disease of the myocardium itself is rare. We describe an 18-year-old male with HL who presented with a large mediastinal mass, pericardial effusion, and tumor invasion of both atrial walls with intra-atrial extension. A PubMed search of publications between 1989 and 2022 was conducted and additional older references were identified among these publications.
