Abstract

Solitary Fibrous Tumors (SFTs) are uncommon mesenchymal tumors of fibroblastic/myofibroblastic origin that stem from various anatomical sites. Most SFTs are asymptomatic and noticed incidentally by various imaging modalities. Although SFTs were initially identified in the pleura and erroneously considered to originate solely from serosal layers, extrapleural SFTs have been reported more commonly than their pleural counterparts. Imaging features are similar in different anatomical locations and are mainly related to the tumor's size and collagen content, characteristically displaying low signal intensity on Magnetic Resonance Imaging (MRI). Smaller tumors typically exhibit uniform enhancement, yet necrotic regions may become evident as the tumor size increases, resulting in heterogeneous enhancement. Less than 30% of SFTs demonstrate unfavorable clinical outcomes regardless of their histological features, warranting surgery as the preferred treatment with long-term follow-up. In this article, we have reviewed the clinical manifestations and imaging features of SFTs, discussed their differential diagnosis based on anatomical site, and provided diagnostic pearls.

孤立性纤维瘤:一种来自常见解剖位置的罕见肿瘤
单发纤维性肿瘤(SFTs)是一种不常见的间叶性肿瘤,由纤维母细胞/肌纤维母细胞引起,源于不同的解剖部位。大多数 SFTs 无症状,可通过各种成像方式偶然发现。虽然 SFTs 最初是在胸膜中发现的,并被错误地认为仅起源于浆膜层,但胸膜外 SFTs 的报道比胸膜内 SFTs 更为常见。不同解剖位置的成像特征相似,主要与肿瘤的大小和胶原含量有关,在磁共振成像(MRI)上通常表现为低信号强度。较小的肿瘤通常表现为均匀强化,但随着肿瘤体积的增大,坏死区域可能会变得明显,从而导致异质性强化。无论其组织学特征如何,只有不到 30% 的 SFT 表现出不利的临床结果,因此手术是长期随访的首选治疗方法。在本文中,我们回顾了 SFTs 的临床表现和影像学特征,讨论了基于解剖部位的鉴别诊断,并提供了诊断要点。
