恶性纤维组织细胞瘤(MFH)是成年人最常见的原发性软组织肉瘤。常发生于肢体近端的深部、腹膜后和躯干。由于其起源于包括骨组织的间叶组织,因而可发生于任何部位。内脏不常见而原发于肝脏者更为罕见,近12年的文献中仅有22例报道。作者描述了3例原发性肝脏MFH CT的主要特征。 例1 62岁女性,10年前曾有小叶乳腺癌病史。一个月来持续不适,低烧和体重减轻。因右上腹疼痛而行US检查,可见一大的低回声假囊肿占据肝右叶大部,数个病灶使囊壁界限模糊。
Malignant fibrous histiocytoma (MFH) is the most common primary soft tissue sarcoma in adults. It usually occurs in the deep part of the limb, behind the retroperitoneum, and in the trunk. Because it originates from the mesenchymal tissue including bone tissue, it can occur at any site. Uncommon visceral organs are more common in the liver than in the liver. Only 22 cases have been reported in the past 12 years. The authors describe the main characteristics of three cases of primary liver MFH CT. Example 1 A 62-year-old woman had a history of lobular breast cancer 10 years ago. Discomfort, low fever and weight loss continued for a month. US examination of the right upper quadrant pain showed that a large hypoechoic pseudocyst occupied the majority of the right lobe of the liver and several lesions blurred the wall boundary.
