[Right intraventricular tumors. Apropos of a case].

The authors report a case of right ventricular tumour in a 16 year old girl who presented with dyspnoea on effort, chest pain on exertion and loss of consciousness. The diagnosis was made on the basis of abnormal right intraventricular echoes on two dimensional echocardiography and was confirmed by angiography. The patient was operated with success. Histology revealed a mesenchymoma, a benign tumour, but whose infiltrating nature calls for a reserved prognosis. The echocardiogram can be used for regular post-operative surveillance. The young patient is well after 18 months' follow-up.
