A Giant Mass Filling the Left Atrium: A Case Report

Background: Cardiac tumors have heterogeneous and unspecific clinical presentations which is why their diagnosis is difficult. Case Report: A middle-aged woman presented to the emergency department with unspecific symptoms developing over 2 weeks. Multimodality imaging revealed a large mass filling the left atrium with a large base adherent to the fossa ovalis and flow obstruction. After surgical extraction, the anatomopathological analysis was compatible with a primary benign cardiac tumor. Conclusion: Clinical presentation of cardiac tumors is usually unspecific and multimodality imaging is crucial in the diagnostic workflow. Surgical excision should be performed as quickly as possible.
