A 49-year-old man was referred for dizziness and malaise. Echocardiogram showed a 3x2.5 cm mass within the left ventricle. A contrast-enhanced 16-row multislice computed tomography (MSCT) scan with retrospective ECG-gated reconstruction confirmed the mass, without infiltration of the left ventricular wall or marked coronary artery stenosis (fig 1
). Surgical resection of the mass was performed, and 6 days later, the patient was discharged from hospital without radiotherapy or chemotherapy.

On pathological examination, the gross appearance was that of a soft, tan–yellow mass with smooth contours. Haemorrhagic areas were noted. The cells exhibited marked pleiomorphism and abundant mitotic figures. The tumour cells were positive for muscle cell antigen/CD34 and smooth muscle actin. Immunohistochemical stains were diffusely positive for vimentin and focally
