A rare case of straight sinus thrombosis in a 36-year-old female with
sudden onset of status migrainosus is presented. This condition was de
monstrated by a linear density in the midline on a noncontrast compute
d tomography scan, as a filling defect at the location of straight sin
us on magnetic resonance imaging, and by the inability to visualize bl
ood flow in the straight sinus on magnetic resonance venography, with
a similar demonstration on a 4-vessel digital subtraction angiography.
