Cerebral venous sinus thrombosis (CVST) on non-contrast CT (NCCT) is often challenging to detect. We retrospectively selected 41 children and 36 adults with confirmed CVST and two age-matched control groups with comparable initial symptoms. We evaluated NCCT placing four small circular ROIs in standardized regions of the cerebral dural venous system.

Materials And Methods: All patients underwent 1.5-T non-EPI DWI-MRI 6 to 9 months after surgery: those showing a hyper-intense signal in the middle ear underwent a revision surgery, whilst the others are still under radiological follow-up and were not considered in this study.
