Fibrolipoma of the mitral valve in a child. Clinical and echocardiographic features.
Echocardiographic examination, performed in a 12-year-old boy who had signs of mitral regulation, showed the presence of an abnormal mass of echoes in the left atrium and mitral orifice. These were initially interpreted as representing an atrial myxoma. Surgical exploration showed that the tumor originated from the posterior leaflet of the mitral valve, and, microscopically, the lesion was diagnosed as a fibrolipoma. The clinical and echocardiographic features of this unique type of cardiac tumor are discussed.
