Atypical Presentation of Constrictive Pericarditis With Constrictive Physiology on Cardiac MRI.

Constrictive pericarditis (CP) is a disease primarily affecting the pericardial sac surrounding the heart. The constrictive physiology placed on the heart chambers can lead to clinical presentations mimicking heart failure and possibly primary liver disease. The diagnosis can often be missed and attributed to other etiologies until the patient undergoes extensive workup to rule out each potential etiology. Diagnosis can be delayed, leading to suboptimal outcomes and mortality rates. Here, we present a case of CP initially presenting with bilateral lower extremity and scrotal edema, initially attributed to alcoholic liver cirrhosis given the patient's history of alcohol abuse. Subsequent abdominal imaging found no evidence of cirrhosis, coupled with grossly normal echocardiogram that led to extensive workup and eventually the diagnosis of CP based on cardiac MRI. The patient later underwent pericardiectomy and made a full recovery. This case highlights the often ambiguous presentation of CP, the utility of cardiac MRI in diagnosis, and the need for specific criteria to help guide future diagnoses as imaging modalities continue to evolve.
