There is a dilated right superficial temporal vein, which communicates with a cluster of dilated superficial veins near the posterior parietal vertex and proximally drains into the right retromandibular vein.
The cluster of superficial vessels crosses midline before looping back to give rise to a single large venous channel that penetrates the diploic space before terminating in the superior sagittal sinus.
Normal flow signal within the venous structures including the superior sagittal sinus, interior cerebral veins, sigmoid sinuses, straight sinus, and transverse sinuses.
