The goal of this pictorial essay is to illustrate the multimodality imaging features of pleural and extrapleural solitary fibrous tumors.
Solitary fibrous tumors tend to be well-defined, ovoid, heterogeneously enhancing lesions. MRI characteristically depicts areas of low signal intensity that correspond to dense collagen. The findings of lesion multiplicity and hypermetabolism on PET images should raise the suspicion of malignancy.
本影像学图集旨在阐述胸膜和胸膜外孤立性纤维瘤的多模态影像学特征。
孤立性纤维瘤往往边界清楚、呈卵圆形、不均匀强化。MRI 特征性地显示低信号强度区域,对应于致密胶原。病变多发性和 PET 图像上的高代谢表现应提示恶性肿瘤的可能性。
