Cortical vein thrombosis, also known as superficial cerebral vein thrombosis, is a subset of cerebral venous thrombosis involving the superficial cerebral veins, often coexisting with deep cerebral vein thrombosis or dural venous sinus thrombosis. Cerebral venous thrombosis accounts for 0.5–1% of strokes, and often remains a diagnostic challenge as the clinical presentation of CVST is highly variable.

FOIA 3.3) is a part of the superior group of dural venous sinuses, 1 and as a member of the superficial cerebral venous system, it drains the superficial surfaces of both cerebral hemispheres. The inferior sagittal sinus is highly variable in extent of development and course. CT is the initial imaging technique to exclude an arterial territorial infarct. Superior sagittal sinus (Sinus sagittalis superior) The superior sagittal sinus is one of several endothelial-lined spaces in the brain known collectively as the dural venous sinuses.It lies within the superior convex margin of the falx cerebri which attaches to the internal surface of the calvaria (in the midline).. This condition has not, to our knowledge, been described previously. It demonstrated an absence of deep cerebral venous system opacification (including straight sinus, superior sagittal sinus, Galen's vein and internal cerebral veins). Cerebral dural sinus thrombosis. The empty delta sign on contrast imaging appears as enhancement in veins adjacent to the superior sagittal sinus with non-enhanced thrombus in the centre of the sinus. A case of a five-year-old boy with nephrotic syndrome is described here. A 44-year-old woman with headache was referred to our institution for further investigation. Drained blood enters the major dural sinuses: Superior sagittal sinus (SSS), inferior sagittal sinus (ISS), lateral sinus (LS), cavernous sinus and straight sinus, and then to the internal jugular vein (IJV) Superficial venous system has numerous anastomses and predominantly drain the SSS and the LS Computed tomography (CT) of the head showed thrombosis in the left transverse and sigmoid sinuses.

Intracranial hypertension, venous cerebral infarction, and seizures are the most prominent clinical features of CVST (1, 2).Neonates, in general, have a greater risk of poor outcomes, while children show a better outcome and make a full recovery (). In a comparative study of CT venography with DSA in imaging cerebral venous anatomy and pathologic conditions, MPR images from CT venography were superior to DSA images in showing the cavernous sinus, inferior sagittal sinus, and basal vein of Rosenthal (, 3).

A computed tomography (CT) venography was performed to rule out vascular implication (Fig. Privacy, Help 1 For a long time, CVT was seen as a rare and severe illness resulting in seizures, focal deficits, and often death. The inferior sagittal sinus (also known as inferior longitudinal sinus), within the human head, is an area beneath the brain which allows blood to drain outwards posteriorly from the center of the head.It drains (from the center of the brain) to the straight sinus (at the back of the head), which connects to the transverse sinuses. Those authors concluded that CT venography is superior to MR venography in identifying cerebral veins and dural sinuses and is at least equivalent in diagnosing dural sinus thrombosis.
