Solitary fibrous tumors (SFT) and meningiomas (MA) have similar clinical and radiographic presentations but require different treatment approaches and have different prognoses. This emphasizes the importance of a correct preoperative diagnosis of SFT versus MA.
In this study, investigated the differences in imaging characteristics between SFT and MA to improve the accuracy of preoperative imaging diagnosis of SFT.
The clinical and imaging data of 26 patients with SFT and 104 patients with MA who were pathologically diagnosed between August 2017 and December 2022, were retrospectively analyzed. The clinical and imaging differences between SFT and MA, as well as between the various pathological grades of SFT, were analyzed.
Age, gender, cystic change, flow void phenomenon, yin-yang sign, lobulation, narrow base, tumor/cortex signal ratio (TCSR) > 1.0 in T1-weighted imaging (T1WI), TCSR ≥ 1.1 in T2-weighted imaging (T2WI), peritumoral edema, and absence of dural tail sign varied between SFT and MA. As per the receiver operating characteristic (ROC) curve analysis, TCSR > 1 in T1WI has the maximum diagnostic accuracy for SFT. Cranial or venous sinus invasion had a positive effect on SFT (Grade III, World Health Organization (WHO) grading).
Among the many radiological and clinical distinctions between SFT and MA, TCSR ≥ 1 exhibits the highest predictive efficacy for SFT; while cranial or venous sinus invasion may be a predictor of WHO grade III SFT.
孤立性纤维瘤（SFT）和脑膜瘤（MA）具有相似的临床和影像学表现，但需要不同的治疗方法且预后不同。这凸显了术前正确诊断SFT与MA的重要性。
本研究调查SFT和MA在影像学特征上的差异，以提高SFT术前影像诊断的准确性。
回顾性分析2017年8月至2022年12月间经病理诊断的26例SFT患者和104例MA患者的临床及影像资料。分析SFT和MA之间以及SFT不同病理分级之间的临床和影像差异。
年龄、性别、囊变、流空现象、阴阳征、分叶、窄基底、T1加权成像（T1WI）中肿瘤/皮质信号比（TCSR）>1.0、T2加权成像（T2WI）中TCSR≥1.1、瘤周水肿以及无硬膜尾征在SFT和MA之间存在差异。根据受试者操作特征（ROC）曲线分析，T1WI中TCSR>1对SFT具有最大诊断准确性。颅骨或静脉窦侵犯对SFT（世界卫生组织（WHO）分级III级）有正向影响。
在SFT和MA之间众多的影像学和临床差异中，TCSR≥1对SFT具有最高的预测效能；而颅骨或静脉窦侵犯可能是WHO III级SFT的一个预测指标。
