case_images: In view of the condition, a brain computed tomography (CT) was performed and this revealed dense triangle sign and dense clot sign (figure 1). 
case_images: Magnetic resonance imaging of brain showed empty delta sign (A, arrowed) and magnetic resonance venography confirmed a diagnosis of cerebral venous sinus thrombosis (B
