title: Multiple Deep White Matter Hyperintense Lesions on Diffusion-Weighted Imaging: Early Sign of Straight Sinus Thrombosis.
abstract: Straight sinus thrombosis (SST) is a rare type of cerebral venous sinus thromboses and is extremely difficult to diagnose, especially at its acute stage. The diagnosis is often delayed in many cases of SST that leads to treatment delay and a poor prognosis. We report the case of a 67-year-old patient who had multiple deep white matter (DWM) hyperintense signals on diffusion-weighted imaging (DWI) immediately after the onset of SST. This DWM hyperintense signal on DWI was the only abnormality at the acute stage, the underlying cause of which was congestive cerebral ischemia. Taken together, DWM hyperintense signals on DWI could be a useful diagnostic imaging marker for the early detection of SST.
