case_images: (a) Coronal contrast-enhanced CT scan of the brain reveals a filling defect along the superior sagittal sinus, presenting as a delta sign (indicated by an arrow). (b) Sagittal contrast-enhanced CT scan of the brain displays a tubular filling defect along the posterior aspect of the superior sagittal sinus (highlighted by an arrow).

case_images: A contrast-enhanced head computed tomography (CT) scan revealed a filling defect along the superior sagittal sinus, resembling a delta sign, as well as a tubular filling defect along the posterior aspect of the superior sagittal sinus (Figure 1a and b).
case_images: (a) Axial T1WI-SE brain MRI shows slightly high signal intensity of superior sagittal sinus posteriorly (arrow) compared to cerebral white matter. (b) and (c) Axial T2-weighted and Diffusion-weighted Imaging (DWI) Brain MRI depicting high signal intensity along the posterior aspect of the superior sagittal sinus (indicated by arrows) respectively. (d) and (e) Sagittal T2-weighted spin echo (T2WI- SE) and coronal T1-weighted spin echo (T1WI-SE) brain MRI demonstrating hyperintensity along the posterior aspect of the superior sagittal sinus and the right vein of Trolard (superior anastomotic vein) respectively. (f) and (g) The MRV reveals a focal absence of blood flow (filling defect) along the posterior portion of the superior sagittal sinus and the right vein of Trolard (superior anastomotic vein).

case_images: Magnetic resonance imaging (MRI) with MRV conducted on the second day of admission revealed a focal filling defect in the right anastomotic vein and the posterior segment of the superior sagittal sinus (Figure 2a-g).
