Figures & Tables

Figure 1

19-year-old female with thrombosis (arrow) of the left transverse sinus (LTS) (A) and superior sagittal sinus (C), confirmed by CT venography in sagittal (B) and axial (D) reconstruction. Average attenuation inside the LTS was 83.6 HU.

Figure 2

Left transverse sinus (LTS) of a 26-year-old male appeared hyperattenuated on non-contrast computed tomography (arrow) (A) and was interpreted as thrombosed by both readers. However, CT venography in axial (B) and sagittal (C) reconstruction showed patency of the LTS. Average attenuation inside the LTS was 60 HU.

The attenuation values between cerebral venous sinus thrombosis (CVST) patients and control group were significantly different (73.4 ± 14.12 HU vs. 58.1 ± 7.58 HU; p = 0.000). HU, Hounsfield units.
