We reviewed the clinical information and imaging studies of 50 patients with documented CVST. Imaging modalities included CT, MRI (T1WI, T2WI, FLAIR, gadolinium enhanced T1WI, gradient echo T2* and diffusion-weighted images (DWI)), MR venography (3D dynamic contrast-enhanced, 3D contrast-enhanced time-of-flight (TOF), 2D TOF, 2D phase contrast), and conventional angiography/venography. The purpose of this exhibit is to demonstrate usual and unusual findings of cerebral CVST and diagnostic pitfalls.
