A 53-year-old male was hospitalized with complaints of cough, fever and backache. Two-dimensional echo-cardiography showed a pericardial echo-free space and a mass in the rightatrium. Based on the MRI findings showing a pericardial mass originating from the atrial tumor, the final diagnosis of leiomyosarcoma was made by a percutaneous pericardial biopsy. Despite various therapies, the patient died after 3 wk. Because of its rareness (to date only 25 case reports), a premortem diagnosis of primary cardiac leiomyosarcoma is generally difficult. However, we feel that MRI and a subsequent biopsy is quite useful for making an early diagnosis of this disease.
