We report here on a case of solitary fibrous tumor of the retroperitoneum, and the tumor displayed a predominantly myxoid histology. A 56-year-old man presented with an incidentally detected retroperitoneal mass. On the MR images, the mass was observed as having iso-signal intensity on the T1-weighted images and high signal intensity on the fat-saturated T2-weighted images. The mass showed intense enhancement on the Gd-DTPA enhanced T1-weighted images. At surgery, a well-defined solid mass was found in the left retroperitoneum. The histological diagnosis was made as solitary fibrous tumor with a predominantly myxoid histology.
我们在此报告一例腹膜后孤立性纤维瘤，该肿瘤主要表现为黏液样组织学特征。一名56岁男性因偶然发现腹膜后肿块前来就诊。在磁共振成像（MR）图像上，该肿块在T1加权图像上呈等信号强度，在脂肪抑制T2加权图像上呈高信号强度。在钆喷酸葡胺（Gd-DTPA）增强T1加权图像上，肿块显示出明显强化。手术时，在左腹膜后发现一个边界清晰的实性肿块。组织学诊断为主要具有黏液样组织学特征的孤立性纤维瘤。
