Caseous calcification is a rare variant of mitral annular calcification, occurring in about 0.06% of echocardiographic studies performed. It is usually a benign lesion, but it should be differentiated by abscess and tumors. Echocardiography is the most sensitive method to identify caseous calcification which appears typically as a round, calcified mass with an echo-lucent, liquid-like inner part.

Unlike mitral annular calcification (MAC), that is a common echocardiographic finding, caseous calcification is a rare variant, occurring in about 0.6% of patient with annular calcification [1–3]. Patient 1.
An 82-year-old woman, with history of hypertension, was admitted to our department for paroxystic atrial fibrillation, which was successfully treated with intravenous Amiodarone. Physical examination revealed a systolic murmur of 2–3/6 L grade. Besides laboratory examinations were substantially normal.
Colour-Doppler examination ruled out shunt between the cyst and the cardiac chambers, moreover colour flow mapping revealed a moderate mitral insufficiency without mitral stenosis. Transesophageal echocardiogram was refused by the patient.
Since there was not dyspnoea, nor left ventricular dilatation, conservative treatment and follow up was considered sufficient.
The authors state that informed written consents were obtained from both the patients for publication of manuscript and figures.
