Abstract
We report MRI and angiographic findings of an unusual giant arachnoid granulation in the left sigmoid sinus in a boy with headache. Its signal intensity was lower than that of cerebral cortex on T1-weighted images and higher on T2 weighting, mimicking dural sinus thrombosis.
摘要
我们报告了一名患有头痛的男孩左侧乙状窦内罕见巨大蛛网膜颗粒的MRI和血管造影结果。其信号强度在T1加权图像上低于脑皮质，在T2加权图像上高于脑皮质，类似硬脑膜窦血栓形成。
