MRI brain showed hemorrhagic infarct in left parietal region [Figures 1 a and b]. MR venogram revealed thrombosis involving superior sagittal sinus and right transverse sinus, later confirmed by digital subtraction angiography [Figure 2a].
(a) Lateral view of the digital subtraction venogram showing poor ante grade flow and substantial superficial collateral drainage indicate thrombosis in the superior sagittal sinus. (b) Repeat digital subtraction venogram, after the infusion of 100,000 U of urokinase through the micro catheter, demonstrating partial recanalization of the superior sagittal sinus

MRI brain showed hemorrhagic infarct in left parietal region [Figures 1 a and b]. MR venogram revealed thrombosis involving superior sagittal sinus and right transverse sinus, later confirmed by digital subtraction angiography [Figure 2a]. Venogram at 48 h showed partial opening up of superior sagittal sinus and complete opening of right transverse sinus [Figure 2b].
