BackgroundCoxsackie B is a viral pathogen that presents with various invasive diseases in adults. Historically, the majority of adult cases with pericarditis or myocarditis have been attributed to coxsackievirus B. The presentation of this viral infection causing effusive-constrictive pericarditis, hepatitis or pancreatitis is rare. This case report is the first to describe a patient with concomitant effusive-constrictive pericarditis, hepatitis and pancreatitis from possible coxsackievirus B infection.Case presentationA 26-year old female was admitted to our hospital with the diagnosis of effusive-constrictive pericarditis complicated by tamponade and cardiac arrest. An emergent pericardiocentesis was performed successfully. Hepatitis and pancreatitis were also identified in our patient. After an extensive workup, coxsackievirus B infection was suspected by positive serum complement fixation antibody titers. Our patient made a full recovery and was discharged from the hospital.ConclusionClinical suspicion of effusive-constrictive pericarditis with tamponade from coxsackievirus B should be considered in patients presenting with chest pain, dyspnea, jugular venous distention, hypotension, ST segment elevation on electrocardiogram, and ventricular interdependence with septal shift during diastole on transthoracic echocardiogram. Initial diagnoses of effusive-constrictive pericarditis resembling cardiac tamponade, hepatitis and pancreatitis can be challenging, and this case highlights the need for healthcare professionals to be cognizant of the association between these unusual clinical presentations and coxsackievirus B infection.Electronic supplementary materialThe online version of this article (doi:10.1186/s12879-016-1752-3) contains supplementary material, which is available to authorized users.
