A second CT of the brain was obtained which revealed persistent hyperdensities in the straight sinus and deep cerebral veins, with new hypodense regions involving bilateral thalami and basal ganglia likely representing edema and venous infarction (Figure 1).

Five hours after the initial angiogram, repeat CT had shown improvement in the thalamic and basal ganglia edema (Figure 2).

Initial noncontrast brain CT showed hyperdense areas along the straight and sagittal sinuses, suggestive of DCST, later confirmed by magnetic resonance venography (MRV) (Figure 4).
