Abstract

We reviewed the magnetic resonance (MR) appearances of 13 malignant fibrous histiocytomas (MFH) of soft tissue and correlated each with the respective lesion's histopathology. The MR images were evaluated for signal intensity on T1- and T2-weighted spin echo sequences, homogeneity of the lesion, presence of internal low signal septations, and margin definition. Histologic subtypes of MFH included storiform-pleomorphic, giant cell, myxoid, and inflammatory. We could not establish a correlation between MR appearance and histopathology. Instead, our series exhibited general features suggestive of malignant soft tissue neoplasms, namely poor margin definition, internal low signal septation, and heterogeneous high signal intensity on T2-weighted images.

摘要

我们回顾了13例软组织恶性纤维组织细胞瘤（MFH）的磁共振（MR）表现，并将其与各自病变的组织病理学进行了关联。对MR图像进行了T1加权和T2加权自旋回波序列上的信号强度、病变的均匀性、内部低信号分隔的存在以及边缘清晰度的评估。MFH的组织学亚型包括席纹状多形性、巨细胞、黏液样和炎症性。我们未能在MR表现与组织病理学之间建立关联。相反，我们的系列病例呈现出提示恶性软组织肿瘤的一般特征，即边缘清晰度差、内部低信号分隔以及T2加权图像上的不均匀高信号强度。
