Abstract

ResumenLa necrosis licuefactiva del anillo valvular mitral se describe como una forma rara de calcificación perianular con un aspecto característico. Suele tratarse de un hallazgo ecográfico incidental que en la tomografía computarizada aparece típicamente como una masa semilunar hipodensa o hiperdensa con un margen de mayor densidad y situada en la zona posterior del anulus. El uso habitual de la TCMD hace que esta entidad se identifique cada vez con más frecuencia, y es importante familiarizarse con ella para evitar errores diagnósticos. Presentamos 3 casos de necrosis licuefactiva del anillo mitral, uno de ellos confirmado quirúrgicamente, y se discuten sus características de imagen y diagnóstico diferencial.

Liquefactive necrosis of the mitral ring is a rare type of periannular calcification that has a characteristic appearance. It is usually discovered incidentally during echocardiography. On CT, it typically appears as a hypointense or hyperintense semilunar mass with margins of greater density that is situated in the area behind the annulus. The routine use of MDCT has led to increasing detection of this entity, and it is important for radiologists to be familiar with these findings to avoid diagnostic errors. We present three cases of liquefactive necrosis of the mitral ring, one of which was confirmed at surgery. We discuss the imaging characteristics and differential diagnosis of this entity.
