A case of malignant fibrosarcoma originated from pericardium was reported. A 31 year-old female who complained of general fatigue and back pain showed dilated cardiac shadow in chest X-ray. Cardiac blood pool scan with 99mTc-RBC revealed avascular mass in pericardial cavity which push the heart up and left side. It was suspected to be malignant, since the mass had increased 67Ga uptake. CT and MRI also demonstrated that the tissue characterization of the pericardial mass was irregular, and the mass compressed venous return. The large mass originated from pericardium caused the right sided cardiac failure. In 12 years ago, she had a history of operation which resected benign hemangioma in the same space (pericardium). We could suspect the malignant transformation between the two rare pericardial tumors; benign hemangioma and malignant fibrosarcoma.
报告了一例起源于心包的恶性纤维肉瘤病例。一名31岁女性，主诉全身乏力和背痛，胸部X线显示心脏阴影扩大。99mTc-RBC心脏血池扫描显示心包腔内有一无血管肿块，将心脏向上和左侧推移。由于该肿块摄取67Ga增加，怀疑为恶性。CT和MRI也显示心包肿块的组织特征不规则，且肿块压迫静脉回流。起源于心包的巨大肿块导致右侧心力衰竭。12年前，她有在同一部位（心包）切除良性血管瘤的手术史。我们可以怀疑这两种罕见的心包肿瘤之间存在恶性转化；良性血管瘤和恶性纤维肉瘤。
