UNASSIGNED: 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.
UNASSIGNED: 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.
■一名88岁的女性出现眼球突出和右眼疼痛。术前成像显示椭圆形,具有软组织密度的明确定义的肿块,散布有界限清楚的病变。病变在计算机断层扫描(CT)扫描中显示低密度,磁共振成像(MRI)扫描的T1/T2加权图像中的高强度和MRI扫描的脂肪抑制图像中的低信号。肿瘤全部切除,病理检查诊断为低度恶性脂肪形成SFT。术后9个月没有复发的证据。
■眼眶脂肪形成SFT的成像特征是散布有脂肪组织的明确定义的实体瘤。这些发现对于术前诊断和治疗的选择至关重要。
