**1. Introduction**

Pericardial diseases are common in clinical practice and include a variety of pathologies such as pericarditis (acute, subacute, chronic, and recurrent), pericardial effusion, cardiac tamponade, constrictive pericarditis, and pericardial masses [1, 2]. The etiology of pericardial diseases is classified into infectious, autoimmune, post-myocardial infarction, and autoreactive causes. When etiology is not apparent, it is classified as idiopathic. Multimodality imaging is an essential approach for a modern and comprehensive diagnostic evaluation [3]. The goal of this text is to highlight the current concepts in the clinical characteristics, presentation, diagnosis, and the treatment for pericardial diseases.
