Giant right ventricular mural vegetation mimicking a cardiac tumour.

Mural vegetations in the course of infective endocarditis are very rare. We report the case of a patient with an extremely large right ventricular free wall vegetation. Establishing diagnosis in the presence of only mural vegetations on echocardiography scan without valve involvement in the inflammatory process was difficult. In a differential diagnosis, benign and malignant tumours, metastases and thrombi were taken into account. The patient was operated upon and the tumour was removed successfully. A histopathological examination revealed an inflammatory character of the tumour. The patient was treated according to antibiogram and discharged home in stable condition.
