This case report describes the features of gadolinium-enhanced MRI in well-differentiated liposarcoma with histologic correlation and addresses the usefulness of this imaging technique in distinguishing well-differentiated liposarcoma from lipoma. Gadolinium-enhanced MRI revealed significantly enhanced signal in well-differentiated liposarcoma in a background of multiple well-differentiated benign fatty masses by showing the increased vascularity in the septa of well-differentiated liposarcoma. Although such signal enhancement can be seen in some types of benign lipomatous tumors with increased blood vessels, this technique is helpful in selection of biopsy site, especially in a clinical setting of multiple fatty masses.
本病例报告描述了钆增强磁共振成像（MRI）在高分化脂肪肉瘤中的特征及其与组织学的相关性，并探讨了该成像技术在鉴别高分化脂肪肉瘤与脂肪瘤方面的实用性。钆增强MRI显示，在多个高分化良性脂肪肿块的背景下，高分化脂肪肉瘤的信号显著增强，这表明高分化脂肪肉瘤间隔内血管增多。尽管在一些血管增多的良性脂肪瘤性肿瘤中也可见这种信号增强，但该技术有助于活检部位的选择，尤其是在存在多个脂肪肿块的临床情况下。
