Tomography (CT) head showed extensive thrombus in the straight and left transverse sinus extending to the left sigmoid sinus and internal jugular vein (IJV) (Figures 1 and 2).
Postcontrast CT axial cut shows filling defect in the transverse sinus suggesting thrombosis (arrow).

This was confirmed on magnetic resonance imaging (MRI) (Figures 3-5) and MR venography (Figure 6). There was no evidence of cerebral hypoperfusion or infarction.
Postcontrast MRI axial cuts show filling defect in the left transverse sinus (arrow).

This was confirmed on magnetic resonance imaging (MRI) (Figures 3-5) and MR venography (Figure 6). There was no evidence of cerebral hypoperfusion or infarction.
Postcontrast MRI axial cuts show filling defect in the left transverse sinus (bold arrow) and normal contrast filling (arrow) in the right transverse sinus.

This was confirmed on magnetic resonance imaging (MRI) (Figures 3-5) and MR venography (Figure 6). There was no evidence of cerebral hypoperfusion or infarction.
MR venography shows filling defect attenuating the left transverse sinus and sigmoid and internal jugular veins (arrow).
