Caseous mitral annulus calcification: A forgotten benign condition mimicking cardiac mass, a case report

Abstract

Key Clinical MessageCaseous mitral annulus calcification is a rare benign condition that can be misdiagnosed on echocardiography especially when it presents as a mass. This report highlights the contribution of cardiac MRI and computed tomography to the diagnosis through the case of a patient previously treated for breast cancer.AbstractWe report the case of a patient, previously treated for breast cancer, in whom echocardiography suggested the diagnosis of a cardiac tumor due the presence of a mass on the posterior mitral annulus. Cardiac magnetic resonance was inconclusive. Computed tomography confirmed the diagnosis of caseous mitral annulus calcification.
