恶性纤维组织细胞瘤是一种多形性间叶肉瘤。它是罕见的主要来自腹腔内。原发性腹膜恶性纤维瘤合并肿瘤出血及破裂是罕见的。我们描述了一个70岁的病人的影像学特征，表现为破裂出血性腹膜MFH在肝下区，伴随着大量的腹腔积血，模仿一个破裂的有蒂肝细胞癌。电脑断层扫描显示一个巨大的不均匀强化的肝下肿块，侵犯邻近的肝脏、胆囊和结肠。同时发现肿瘤出血和破裂并腹膜种植和大量血性腹水。血管造影显示一个富血供的肿瘤，由增大的肝右动脉、胆囊动脉和胃网膜动脉的网膜支供血。病人接受剖腹手术切除肿瘤，但肿瘤在术后一个月复发。据我们所知，腹腔内MFH破裂并发腹腔积血的CT表现以前没有被描述过。
Malignant fibrous histiocytoma (MFH) is a pleomorphic mesenchynal sarcoma. It is uncommonly arises primarily from the intra-peritoneal cavity. Primary peritoneal MFH with tumor bleeding and rupture is rare. We describe the imaging features of a 70-year-old patient presenting with ruptured hemorrhagic peritoneal MFH at subhepatic area, accompanied by massive hemoperitoneum, mimicking a ruptured pedunculated hepatocellular carcinoma. Computed tomography (CT) revealed a large heterogeneous enhanced subhepatic mass with adjacent liver, gallbladder and colon invasion. Tumor hemorrhage and rupture complicated with peritoneal seeding and massive bloody ascites were also detected. Angiography showed a hypervascular tumor fed by enlarged right hepatic arteries, cystic artery and omental branches of gastroepiploic artery. The patient underwent laparotomy for tumor resection, but the tumor recurred one month after operation. To our knowledge, the CT appearance of ruptured intraperitoneal MFH complicated by hemoperitoneum has not been previously described.
