摘要:
目的     探讨眼眶孤立性纤维瘤(solitary fibrous tumor,SFT)的CT和MRI诊断价值。     方法       回顾性分析经病理证实的5例眼眶SFT的CT和MRI表现,其中2例只行CT检查,2例只行MRI检查,1例同时有CT和MRI检查。患者中女性3例,男性2例,年龄33~54(中位年龄46)岁。影像表现主要评价其部分、大小、边缘、CT密度、MRI信号和增强方式。     结果       5例病变均表现为边界清楚的软组织肿块,最大直径2.1~3.5 cm。3例位于球后肌锥外,2例位于球后肌锥内。3例CT上表现为稍高密度或等密度,其中1例其内可见点状钙化;3例MRI检查T1WI表现为等信号或稍低信号,信号相对均匀,而T2WI则信号稍混杂,其中1例等信号为主,混杂有高、低信号影,另2例肿块大部分表现为明显高信号,其内可见散在斑状、小片状低信号影。增强检查肿块均表现为明显欠均匀强化。     结论       眼眶SFT的MRI表现有一定特征性,应纳入眼眶富血供肿瘤鉴别之列。
Abstract:
Objective       To evaluate the CT and MRI features of solitary fibrous tumor (SFT) in the orbit.      Methods       CT and MR images of 5 patients with pathologically identified SFT were retrospectively reviewed. Two of these patients underwent CT scanning, 2 underwent MR imaging, and 1 underwent both examination. They were inpatients of optical ward from two hospitals of the authors during 2004 to 2009, 3 female, 2 male, age from 33 to 54 (median age 46). The imaging findings on the location, size, margin, CT density, MRI signal intensity, and pattern of enhancement of the lesion were analyzed.      Results       All 5 lesions were found as a well-defined mass, ranging from 2.1 to 3.5 cm in size. Three tumors were located in the extraconal space, and the left 2 in the intraconal space. CT scan showed that 3 lesions were of isodensity or slightly high density, and punctate calcification was found in one of them. MRI showed 3 lesions were of homogeneous isointense or slightly low signal intensity on T1WI and heterogeneous mixed signal intensity on T2WI. One lesion showed isointense signal intensity mainly but mixed with hyperintense and hypointense signal intensity on T2WI. The other 2 lesions showed evident hyperintense signal intensity mainly but mixed with hypointense signal intensity plaque on T2WI. All 5 lesions showed marked heterogeneous enhancement.      Conclusion       Orbit SFT demonstrates some characteristic MRI features and might be included in the differential diagnosis of soft tissue masses in the orbit.
