C29. Chronic Pericardial effusion associated with Cytomegalovirus

Abstract

Abstract Pericardial effusion is one of the most challenging clinical condition to determine the etiologies. A 60 yo woman presented with atypical sign of pericardial effusion. She visited several physicians and without any clinical improvement. Echocardiography revealed 133.5 ml pericardial effusion and pericardial thickness of 12,14 mm. Cardiac MRI was then performed and indicated, thickening of pericardium (4.8-5.1mm) at lateral right atrium, RV free wall and apical RV. The thickened part of the pericardium at apical RV has rigid, immobile appearance. Moderate amount of pericardial effusion prominently located at basal of heart. Pericardial effusion was at superior and lateral right atrium, apical RV and LV, and lateral, inferior, anterior left ventricle. Serology tests Anti CMV IgG reactive, anti CMV IgM non reactive and TB quantiferon negative. These results confirmed the pericarditis associated with CMV infection. The biggest challenge for the clinician is to find out an etiologic diagnosis. The common causes of pericarditis are infection (viral, bacterial), metabolic (renal failure, hypothyroidsism), cancer, myocardial infarction, and post traumatic. Among infectious causes, the enteroviruses, herpesviruses and mycobacterium tuberculosis are the most common causes. Cytomegalovirus belongs to the herpesviruses group. Clinician should be aware about the possible etiologies, as chronic pericarditis is a condition that requires comprehensive and multidisciplinary approaches.
