PURPOSE
We describe a case of fat-forming solitary fibrous tumor (SFT) of the orbit with typical findings on imaging that may improve the awareness of orbital fat-forming SFT.
OBSERVATIONS
An 88-year-old female presented with exophthalmos and pain in her right eye. Preoperative imaging showed an oval, well-defined mass with soft-tissue density, interspersed with a well-circumscribed lesion. The lesion showed low-density in computed tomography (CT) scans, hyperintense in T1/T2 weighted images of magnetic resonance imaging (MRI) scans and hypointense in fat-suppressed images of MRI scans. The tumor was removed en bloc and diagnosed as low-grade malignant fat-forming SFT by pathological examination. There was no evidence of recurrence 9-month postoperatively.
CONCLUSIONS
The imaging feature of orbital fat-forming SFT is a well-defined solid tumor interspersed with adipose tissue. Such findings are vital for the preoperative diagnosis and the choice of the treatment.
目的
我们描述一例眼眶脂肪形成性孤立性纤维瘤（SFT）病例，其具有典型的影像学表现，这可能会提高对眼眶脂肪形成性SFT的认识。
观察结果
一名88岁女性因右眼眼球突出和疼痛就诊。术前影像学检查显示一个椭圆形、边界清晰的软组织密度肿块，内有一个边界清晰的病变。该病变在计算机断层扫描（CT）中呈低密度，在磁共振成像（MRI）的T1/T2加权图像中呈高信号，在MRI脂肪抑制图像中呈低信号。肿瘤被整块切除，病理检查诊断为低度恶性脂肪形成性SFT。术后9个月无复发迹象。
结论
眼眶脂肪形成性SFT的影像学特征是一个边界清晰的实性肿瘤，内有脂肪组织。这些表现对于术前诊断和治疗选择至关重要。
