目的对比分析眼眶孤立性纤维瘤的CT与MRI表现。方法对以往的14例眼眶孤立性纤维瘤(SFT)的CT和MRI进行分析。结果单发SFT的14例,2例SFT发生在跨肌锥内、外生长;4例SFT发生在肌锥外;8例SFT发生在肌锥内。所有SET患者中有12例患者在进行CT或者进行MRI增强后,SFT有明显的强化现象,而有6例进行CT的患者强化的表现方式为快进快出。结论眼眶SFT的特征性影像学表现为:SFT CT强化病灶的表现方式为快进快出,在MRI出现管状或者血管留空的信号。
Objective To compare CT and MRI findings of orbital solitary fibroma. Methods The CT and MRI of 14 cases of orbital solitary solitary fibroma (SFT) were analyzed. Results Single SFT in 14 cases, 2 cases of SFT occurred in the transmuscle conus, external growth; 4 cases of SFT occurred outside the muscular cone; 8 cases of SFT occurred in the muscular cone. Twelve patients in all SET patients experienced significant enhancement of SFT after performing CT or MRI enhancement, while six patients undergoing CT showed an enhanced manifestation of fast-forward and fast-response. Conclusions The characteristic imaging features of orbital SFT are as follows: The enhancement of SFT CT is manifested by fast-forward and fast-moving, and the signals of tubular or vascular emptying appear in MRI.
