| Abstract |
|---|
The present report describes the case of a 55-year-old woman who suffered from cardio-embolic stroke originating from malignant fibrous histiocytoma (MFH) localized on the mitral valve. The patient underwent transthoracic two-/three-dimensional and transoesophageal echocardiography which demonstrated the mass protruding in the outflow tract of the left ventricle. Differential diagnosis had to be made with other masses in the left ventricle, such as thrombi, vegetations, and cardiac tumours. Surgery was performed to remove the tumour and the surgery findings confirmed echocardiographic images. Primary cardiac tumours are a rare entity, and their incidence is
0.0017–0.019%. The majority of them are benign, but in a quarter of cases they are malignant. This case is an example of an MFH which caused embolism to the central nervous system.
