No clinical significance could be given to the existence of any of these arachnoid granulations. We report 5 patients with unilateral CSVT associated with a hypoplastic contralateral venous draining sinus that developed raised ICP and papilledema and compare them with 6 patients with normal contralateral venous sinuses without elevation of ICP. It is seen in only one third of cases. Therefore, we chose medical treatment in anticipation of collateral circulation development. AJR 2007; 189:S64-S75, by J van Gijn The aim of this study was to report 6 pediatric patients with unilateral CSVT with contralateral hypoplastic venous sinuses whose course was complicated by increased ICP and development of papilledema. Three of these patients underwent anticoagulation, and no associated complications were reported. There is a broad differential diagnosis including arterial infarction, infection, tumor etc. All rights reserved. The 12 consecutive pediatric patients with unilateral CSVT were analyzed. However, our patient showed no improvement of clinical manifestations after medical treatment for 6months, indicating the collateral circulation was not fully developed. Venous thrombosis leads to a high venous pressure which first results in vasogenic edema in the white matter of the affected area.

October 2006 RadioGraphics, 26, S19-S41, by J. Linn et al We support the call for larger studies including adult and pediatric populations with unilateral CSVT and contralateral venous draining sinus hypoplasia. Absence of normal flow void on MR-images can be very helpful in detecting venous thrombosis, but there are some pitfalls as we will discuss later. The sigmoid sinus is a dural venous sinus that lies deep within the human head, and just below the brain. On spin-echo images patent cerebral veins usually will demonstrate low signal intensity due to flow void. https://doi.org/10.1161/STR.0b013e31820a8364.

On the left images of a patient with hypoplasia of the left transverse sinus. Contrast-enhanced MR venography has the disadvantage that you need to give contrast, but has less pitfalls. Time-of-flight MRV is often used to evaluate the intracranial dural sinuses and confirm or exclude CSVT.7 Variations in the normal anatomy of venous sinuses not only make the diagnosis of CSVT more difficult but also imply a different prognosis and could justify a more aggressive treatment approach. When the proces continues it may lead to infarction and development of cytotoxic edema next to the vasogenic edema. Patients diagnosed with a unilateral cerebral sinovenous thrombosis were identified by querying our institutional radiology data base. The initial search identified 101 patients. She was referred to the neurosurgery department for suspected abnormally high intracranial pressure (ICP). Intracranial venous hypertension has been associated with a few cases of meningioma secondary to compression of the venous sinus. SY and FM contributed to the obtainment and interpretation of the clinical information. Sindou MP, Alvernia JE. It is called an empty sella because the sella is mainly filled with CSF as the hypofysis is compressed downwards due to the increased intracranial pressure.
