Abstract

We describe a 61-year-old man who presented with an extrathoracic solitary fibrous tumor (SFT) of the pelvic peritoneum with central malignant degeneration as seen on computed tomography (CT), magnetic resonance imaging (MRI), and histopathology. When a central focus of heterogeneity and variable contrast enhancement are identified within a fibrous tumor of the pelvis on CT or MRI, malignant degeneration of an extrathoracic SFT, although rare, should be considered as a diagnostic possibility.

摘要

我们描述了一名61岁男性，其盆腔腹膜出现胸外孤立性纤维瘤（SFT），计算机断层扫描（CT）、磁共振成像（MRI）及组织病理学检查显示有中央恶性退变。当在CT或MRI上盆腔纤维瘤内发现不均匀的中央灶及不同程度的对比增强时，应考虑胸外SFT发生恶性退变的可能性，尽管这种情况很罕见。
