Meningiomas are the most common neoplastic lesion causing venous hypertension. Conventional angiography demonstrated the dominant right transverse sinus with hypoplastic left transverse sinus and subtotal occlusion of the dominant right sigmoid sinus in the venous phase, and a mass lesion causing severe luminal narrowing (Fig. The sigmoid sinus moves in a downward manner through an S-shaped groove. It is plausible that if the dominant venous sinus is occluded due to a thrombus, the contralateral side will not drain sufficiently and there will be an increased predisposition to the development of increased ICP. We investigated methods for improving blood flow by intravascular surgery such as stent placement and percutaneous transluminal angioplasty using a balloon. Cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the brains venous sinuses. Learn how we can help 4.4k views Reviewed >2 years ago Thank The transverse and sigmoid sinuses were exposed by drilling of the petrosal bones. Five of 6 patients had elevated ICP confirmed by papilledema. Vein of Trolard, which is the largest cortical vein that drains into the superior sagittal sinus. Surgical treatment or intravascular surgery may be high risk without knowing specific location of the mass lesion, inside or outside the sinus, and without knowing the pathological type. Papilledema confirmed on ophthalmologic assessment was used as our noninvasive criterion standard to diagnose elevation of ICP. Basic demographic data and clinical characteristics, imaging findings, and location of the CSVT as well as the presence of elevated ICP with associated symptoms can be found in the On-line Table. Objective: To examine the association between hypoplasia of the transverse sinus and ipsilateral transverse sinus (TS) thrombosis Background: Transverse sinuses (TS) are frequently asymmetric. Hypoplasia and aplasia of the right or left transverse sinus is a common finding. Several patients had headache. b Right presigmoid craniectomy was performed. This may lead to raised intracranial CSF pressure as assessed by lumbar puncture. it is normal. Accurate diagnosis of subtypes of transverse sinus (TS) hypoplasia requires more expensive methods like magnetic resonance (MR) imaging. Extensive neuro-ophthalmologic examination revealed mild visual field abnormalities. Chronic dural sinus thrombosis can lead to dural arteriovenous fistula formation and to increased CSF pressure. It is connected through the mastoid and the condylar messenger veins with the pericranial nerves. Lead a healthy lifestyle which includes eating a low-fat diet made up mostly of fruits and vegetables, low-fat meats and proteins, low-fat dairy products, and whole-fiber grains, breads, cereals, and pasta. None of the authors have received any financial assistance related to the present manuscript. These bilateral findings should raise the suspicion of deep cerebral venous thrombosis. Pseudotumor cerebri due to partial obstruction of the sigmoid sinus by a cholesteatoma. Torcular, transverse, and sigmoid sinus meningiomas. For example, one study demonstrated 1: 39% hypoplasia of the left sinus. 2b). To investigate the imaging characteristics, prevalence, and clinical significance of arachnoid granulations in the transverse and sigmoid venous sinuses. "Hypoplastic left transverse, sigmoid and jugular venous system with superimposed diffuse moderately severe irregular narrowing and flow reduction of the straight sinus and left transverse sinus with almost absent flow in the sigmoid sinus and left jugular vein; with collateral vessels, indicative of multifocal venous sinus thrombosis" Skull metastasis of Ewing's sarcoma--three case reports. This condition may also be called cerebral sinovenous thrombosis. In january 2009 there are signs of intracranial hypertension like CSF surrounding the optic nerve and CSF within the stalk of the hypophysis. On the contrast enhanced T1 images on the left there is an area of low signal intensity within the enhancing transverse sinus. When the proces continues it may lead to infarction and development of cytotoxic edema next to the vasogenic edema. Google Scholar. Both testicles have veins that attach at different locations. Please enable it to take advantage of the complete set of features! A dural sinus is a channel that lies between the dura mater, the outermost tissue covering the brain. The next step has to be a contrast enhanced study. Mittal S, Wu Z, Neelavalli J, Haacke EM. The draining, The maxillary sinus is one of the four paranasal sinuses, which are sinuses located near the nose. In cases of total absence or hypoplasia of both the transverse sinus and sigmoid sinus, the superior petrosal sinus may pass directly through the mastoid foramen, and a large inferior petrosal sinus may be present. On the far left we see a dense vessel sign on the unenhanced CT. Magnetic resonance (MR) imaging revealed a small (2.5cm) lesion located in the right sigmoid sinuses appearing as isointense on T1-weighted images, and isointense on T2-weighted images, with homogeneous enhancement following intravenous administration of gadolinium (Fig. In all patients with CSVT, especially in those with a hypoplastic contralateral venous sinus, an ophthalmologic evaluation as an indirect measure of elevated ICP is essential. f Conventional angiogram, venous phase, showing the mass lesion apparently located at the inner sinus wall mimicking venous thrombosis. what does stenosis of transverse and sigmoid sinuses mean on a mrv? One patient was lost to follow-up. Children and adults have different risk factors for CVST. Although unilateral hypoplastic venous draining sinus is a common incidental and benign variant, in CSVT of the dominant draining side, it can pose a considerable problem, leading to increased ICP and substantial morbidity. However, the present tumor was attached to the roof of the sigmoid sinus, with possible extension into the sinus, and consequently is outside the classification. 1986;43(5):51921. when the contrast is gone. May occur with symptoms, may be asymptomatic. Most cases of venous invasion remain asymptomatic because of the development of venous collaterals. Cerebral sinovenous thrombosis (CSVT) affects 0.340.67 per 100,000 children annually.1 Mortality rates are 3%12%,1 and neurologic sequelae can be seen in 22%50% of survivors.2 The etiology is multifactorial and frequently includes acute provoking illnesses such as head and neck infections, dehydration, central venous lines, chronic medical conditions, prothrombotic states, and head trauma.1 The clinical presentation of pediatric CSVT is highly variable and includes headache, papilledema, seizures, and focal neurologic deficits.3 Diagnostic evaluation of pediatric CSVT almost invariably includes brain imaging with CT, possibly along with CTV or MR imaging with MRV. However, in the case of hypoplasia of the contralateral venous sinuses and internal jugular vein, complete occlusion of the ipsilateral sinus may cause fatal consequences.

Saposnik G, Barinagarrementeria F, Brown RD Jr, Bushnell CD, Cucchiara B, Cushman M, et al. We describe a rare case of intracranial hypertension caused by meningioma located inside the dominant sigmoid sinus. The onset of signs and symptoms of CSVT are often insidious, and though vomiting, lethargy, and headache are commonly seen in children with severe otogenic infections, focal neurologic deficits such as diplopia due to a sixth cranial nerve palsy or papilledema warrant brain imaging. Privacy The 12 consecutive pediatric patients with unilateral CSVT were analyzed. AJNR Am J Neuroradiol. Overall, about 3 out of 300,000 children and teens up to age 18 will have a stroke.
