Venous infarct. Forty-three-year-old woman with headache and increased somnolence. DWI (a) and ADC (b) shows punctate foci of reduced diffusion in the right centrum semiovale (arrows). Susceptibility-weighted imaging (SWI) (c) demonstrates linear susceptibility along callososeptal veins, right greater than left (arrow). Magnetic resonance venography (MRV) (d) demonstrates loss of flow-related enhancement in the superior sagittal sinus and expected location of the internal cerebral veins, vein of Galen, and straight sinus (arrows)
