Differentiation of Transverse Sinus Thrombosis from Congenitally Atretic Cerebral Transverse Sinus with Computed Tomography

摘要

BackgroundTransverse sinus thrombosis can have nonspecific clinical and radiographic signs. We hypothesized that the novel “sigmoid notch sign” (on head CT) can help differentiate transverse sinus thrombosis from a congenitally atretic sinus among individuals with absent signal in one transverse sinus by magnetic resonance venography (MRV).
