Decoding Pericardial Effusion: Ultrasonographic Insights for Radiologists

Pericardial effusion is a common finding in clinical practice. It can present incidentally asymptomatically or as a manifestation of systemic or cardiac disease. According to its commitment, it can be classified into mild effusions, generally asymptomatic, up to cardiac tamponade, which can endanger the patient's life. Recent advances make it possible to establish the presence and assess the size of the pericardial effusion, its hemodynamic impact, and clarify the etiology. The aim of this article is to provide an update on the diagnostic and therapeutic approach to pericardial effusion.
