摘　　要：目的探讨上矢状窦内脂肪瘤的形成因素、位置、发病的年龄及发生率。方法对11例上矢状窦内脂肪瘤的CT表现进行回顾性分析。结果11例上矢状窦内脂肪瘤CT表现为典型含脂低密度结节位于上矢状窦内。结论上矢状窦内脂肪瘤多形成于纤维索旁,具有典型CT表现,常见于上矢状窦颅顶部,呈单发结节状,本组仅见于老年人;上矢状窦内脂肪瘤形成上矢状窦内充盈缺损,其对血流动力学影响尚待探讨。Objective To investgate the formation factors,location,age and incidence of lipoma in superior sagittal sinus.Methods CT findings of 11 cases of lipoma in superior sagittla sinus were retrospectively analyzed.Results The CT fingings of 11 cases of superior sagittal lipoma were typical fatty low-density nodules located in superior sagittla sinus.Conclusion Lipomas in superior sagittal sinus are mostly formed near fibrous tissue and have typical CT fingings.They are often seen in the cranial top of the superior sagittla sinus with single nodular appearance.In this group,lipomas are only seen in the elderly.The filling defect of superior sagittla sinus is caused by lipoma in superior sagittal sinus,and is effect on hemodynamics remains to be discussed.
