Giant arachnoid granulation mimicking dural sinus thrombosis in a boy with headache: MRI

Neuroradiology. 1998 Mar;40(3):181-3. doi: 10.1007/s002340050564.


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.
