Caseous necrosis of the mitral annulus is a rare condition which typically involves the posterior leaflet or annulus. We report the case of a 71-year-old female with extensive comorbidities, presenting with dyspnea and angina, who had an incidental echocardiographic finding of a mass on or near the mitral valve. The mass increased in size over the course of three years and was associated with severe mitral regurgitation. The mass was initially thought to be a myxoma, however, surgical exploration revealed caseous necrosis of the posterior mitral annulus. Following removal of the necrotic tissue and distorted mitral leaflet, a bioprosthetic mitral valve was implanted and the patient recovered uneventfully.
二尖瓣环干酪样坏死是一种罕见病症，通常累及后叶或瓣环。我们报告一例71岁女性患者，伴有多种并存疾病，表现为呼吸困难和心绞痛，经超声心动图偶然发现二尖瓣上或其附近有一肿块。该肿块在三年间逐渐增大，并伴有严重二尖瓣反流。肿块最初被认为是黏液瘤，然而手术探查发现是二尖瓣后环干酪样坏死。切除坏死组织和变形的二尖瓣叶后，植入了生物人工二尖瓣，患者恢复顺利。
