Two cases of fat in midline dural sinuses, detected by high-resolution CT, were studied anatomically. The fat nodules were not located in the sinus lumen, but in the sinus wall. They were composed of normal adipose tissue without fibrous encapsulation. Our findings have proved that the fat deposit as demonstrated by CT within these dural sinuses represents normal adipose tissue in the sinus wall and does not necessarily mean the presence of a fatty tumor.
通过高分辨率CT检测到两例硬脑膜中线窦内脂肪病例，并进行了解剖学研究。脂肪结节并非位于窦腔内，而是位于窦壁。它们由正常脂肪组织构成，无纤维包膜。我们的研究结果证明，CT显示的这些硬脑膜窦内的脂肪沉积代表窦壁内的正常脂肪组织，并不一定意味着存在脂肪肿瘤。
