case_images: (a and b): Diffusion-weighted imaging (DWI) and Apparent Diffusion coefficient (ADC) images showing diffusion restriction with corresponding low ADC (marked with circle) in right parietal lobe suggesting acute infarction. (c): Non-contrast 3D time of flight (TOF) MR venogram depicts non-visualisation of right transverse and sigmoid sinus - Suggestive of complete thrombosis (red arrows). (d): Non-contrast 3D TOF MR venogram depicts non-visualisation of posterior two third superior sagittal sinus - Suggestive of complete thrombosis (red arrows).

case_images: Tomography (CT) of the brain which showed hyperdensity along superior sagittal and right transverse venous sinuses suggesting the likely diagnosis of CSVT. The Magnetic Resonance Imaging (MRI) of the brain showed thromboses in posterior half of superior sagittal sinus, right transverse and sigmoid sinuses (Figure 1).

case_images: (a): Axial Fluid Attenuated Inversion Recovery (FLAIR) image depicting mild gyral oedema in bilateral high frontoparietal lobes (red arrows). (b): Gradient Recalled Echo (GRE) image showing blooming in cortical veins in bilateral high frontal lobes (red dashed arrows). (c): Post contrast T1 coronal image showing filling defect in superior sagittal sinus suggesting thrombosis (red arrow head).

case_images: She was evaluated with the MRI of the brain which showed anterior superior sagittal sinus and bilateral superficial cortical venous thrombosis along with subarachnoid haemorrhage (Figure 2).
