title: Intrapericardial giant lymph node hyperplasia.
abstract: This report concerns a female patient aged 42 years known to have asymptomatic cardiomegaly for 2 years. She presented 2 weeks before surgery with chest pain radiating to the left arm and face. Angiography revealed a highly vascular mass in the region of the left atrium. Surgery revealed an intrapericardial tumor adherent to both atria. Histologically this proved to be giant lymph node hyperplasia, an unusual example because of its intrapericardial localization.
