Diffusion- and perfusion-weighted MR imaging of dural sinus thrombosis

A patient with dural sinus thrombosis had progressively worsening symptoms and signs that resolved after intradural thrombolysis, Intradural sinus pre ssures were 54 mm Hg. Echo-planar MR imaging revealed complex abnormalities of diffusion and widespread delay in mean transit time that improved immed iately after thrombolysis. This case suggests that diffusion- and perfusion -weighted imaging can provide valuable information noninvasively to help tr iage patients with dural sinus thrombosis between conservative and aggressi ve management.
