[A case report of mitral valve papillary fibroelastoma leading to embolic stroke]

A 39-year-old man presented with acute onset of left arm and left side face weakness, and mild expressive aphasia. He was referred for two-dimensional echocardiography, which demonstrated a 13 mm diameter pedunculated, mobile, echodense mass attached to the anterior leaflet of the mitral valve. At operation, the tumor was a 10 x 10 x 15 mm, rounded, and yellow-whitish mass with a short stalk arising from rough zone of the anterior leaflet of the mitral valve. The surface appeared to be sean anemone. The mitral valve with this tumor was excised and replaced with a 29 mm St Jude Medical mechanical valve. The pathological findings are typical of a papillary fibroelastoma.
