(26) demonstrated the presence of bilateral transverse sinus
stenosis with a sensitivity and specificity of 93% in patients with IIH using MRV In one study, according to the definition of transverse venous sinus stenosis, it was reported that 100% of the patients with IIH had bilateral stenosis on MRV (29).
A total of 25 bodies were studied (50 sides).In midline just adjacent to the torcula the upper part of the transverse sinus
was found at an average of 13.4 mm (Median 13.4, range 1214.8) above the IZ line on right side and an average of 12.5 mm (Median 12.7, range 11.2-13.4) above the same on left side.
The transverse sinus
was found to be hypoplastic in 88(43.13%) patients.

Cerebral artery MR angiography, bilateral carotis arteries, anterior cerebral artery, pericallosal artery and mid cerebral artery, Willis Polygon arterial structures, basilar artery, and arteria cerebri posterior branches were normal; no aneurysm, malformation or displacement were detected; venous MR angiography revealed a slightly weakened right transverse sinus
calibration (variation) and normal sagittal sinus, straight sinus, left transverse and sigmoid sinus alignments and calibrations.
MR venography showed occlusion of the left transverse sinus
The late venous phase showed persistent capillary blush, posterior third of sagittal sinus occlusion and poor filling of the bilateral transverse sinus
. Superselective embolisations of the left occipital artery, superficial temporal artery and middle meningeal artery were taken with absorbable gelatin sponge particles.
In this case, both MRI and MRV revealed thrombosis of the superior saggital sinus and also the left transverse sinus
. In addition, other findings were consistent with left parietal venous infarction.
