Role of imaging in chronic otitis media and its complications

Figure 4 Lateral sinus thrombosis. A: The coronal post-contrast T1W cerebral magnetic resonance venography image shows loss of signal along the right transverse sinus (orange arrow); B: The coronal post-contrast T1W cerebral magnetic resonance venography image shows loss of signal along the right sigmoid sinus (blue arrow);C: The coronal T2W magnetic resonance image shows hyperintensity due to flow void loss in the right transverse sinus (green arrow); D: Axial T2W magnetic resonance image shows hyperintensity due to flow void loss in the right sigmoid sinus (yellow arrow).
