Abstract
About 90% of cases of acute pericarditis have an idiopathic or viral etiology. In some cases, it is possible to identify high-risk patients for whom hospital admission and specific etiology research are mandatory for adequate treatment. Bacterial pericarditis is uncommon and responsible for less than 1% of cases. Only 10 cases of pericarditis due to Campylobacter fetus have been documented worldwide. This case highlights the importance of good cardiac imaging, with the right clinical and microbiology-integrated approach in high-risk cases of pericardial disease.
