Abstract

Background: Solitary fibrous tumors (SFTs) are rare and can be misdiagnosed because of their various radiological appearances.

Purpose: To clarify the characteristic MRI findings of SFTs by analyzing their radiological-pathological correlation.

Material and methods: Nine consecutive patients with SFT who underwent magnetic resonance imaging (MRI) prior to surgery were analyzed. Eight patients underwent contrast-enhanced MRI, and three underwent dynamic MRI. Radiological-pathological correlation analysis, co-occurrence matrix, run-length matrix, and histogram analysis were performed to assess the relationship between pathological findings T1- and T2-weighted images (T1-WI and T2-WI).

Results: All nine lesions ranged in size from 20 to 36 mm. Seven lesions were located in the superior portion of the retrobulbar space found outside of the muscle cone, and two lesions in the inferior portion were located within it. No significant correlation was observed between the amount of collagenous tissue and the qualitative evaluation of the signal on T1-WI and T2-WI. Kurtosis on T2-WI was significantly correlated with the amount of collagenous tissue (ρ = -0.97, p < 0.0001) and endothelial cells (ρ = -0.49, p = 0.0479).

Conclusion: Kurtosis in the histogram analysis on T2WI showed a strong correlation with the amount of collagenous tissue.

眼眶孤立性纤维性肿瘤的磁共振成像:放射-病理相关性分析。

背景:孤立性纤维性肿瘤(SFTs)是罕见的，并且由于其不同的放射表现而容易被误诊。目的:通过分析SFTs的影像学与病理相关性，明确其特征性MRI表现。材料和方法:对连续9例术前行磁共振成像(MRI)的SFT患者进行分析。8例患者行MRI增强扫描，3例行动态MRI扫描。通过影像学-病理相关分析、共现矩阵、行程长度矩阵和直方图分析评估病理表现T1和t2加权图像(T1- wi和T2-WI)之间的关系。结果:9例病灶大小在20 ~ 36mm之间。7个病变位于肌锥外球后间隙的上半部，2个病变位于下半部。胶原组织的数量与T1-WI和T2-WI信号的定性评价无显著相关性。T2-WI峰度与胶原组织数量(ρ = -0.97, p < 0.0001)和内皮细胞数量(ρ = -0.49, p = 0.0479)显著相关。结论:T2WI直方图峰度与胶原组织的数量有较强的相关性。
