An 89-year-old woman had undergone a medical examination and treatment due to exertional dyspnea symptom and cardiac enlargement, but her symptoms had not improved. According to images from a computed tomography scan, a huge intrapercardial mass excluding the heart was detected, and the patient was referred to our department for surgical treatment. Because of cardiac failure due to the mass excluding the heart, we planned to excise the tumor for cure and also for diagnosis. We did not distinguish the tumor before operation as is often the case with cardiac tumor. The tumor arose from the epicardium of the left ventricular（LV）anterior wall, and was attached to the LV wall with a broad stalk（approximately 3×10 cm）along the left anterior descending coronary artery（LAD). We had to operate under cardiopulmonary bypass and cardiac arrest, since the tumor involved the LAD, so we underwent resection of a part of the LAD. The patient was discharged uneventfully on postoperative day 37. On histopathology, the tumor was diagnosed as a solitary fibrous tumor（SFT）of the epicardium. Cardiac SFTs are rare. Above all, SFTs arising from LV epicardium are very rare. We report this case with some literature review.
