A 39-year-old woman presented to the ophthalmology department of our hospital with discomfort in her eyes. Postoperative MR imaging showed that the tumor was totally resected (Fig. 2008 Aug;29(7):1335-9. doi: 10.3174/ajnr.A1093. 2011;25(4):4926. Contrast-enhanced MR-venography uses the T1-shortening of Gadolinium. 1e-f). volume21, Articlenumber:119 (2021) When you look closely and you may have to enlarge the image to appreciate this, there is also high signal in the basal ganglia on the right. Intracranial hypertension has been associated with a few cases of meningioma secondary to compression of the venous sinus [1,2,3]. 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. Epub 2016 Feb 17. The sigmoid sinus is actually a pair of two sinuses (right and left) that enable veins to spread from the middle of the head downwards. On MRI, one may see increased CSF around the optic nerve and an empty sella. 2013;80(3):28995. On the left a T2-weighted image with normal flow void in the right sigmoid sinus and jugular vein (blue arrow). Often found during examination by percussion and palpation. Both sinuses begin at the internal occipital protuberance of occipital bone , while they terminate by giving off the ipsilateral sigmoid sinus . Univariate analysis was performed to. The mass was located inside the sigmoid sinus. Contrast-enhanced MR venography has the disadvantage that you need to give contrast, but has less pitfalls. On the left images of a patient with an infarction in the area of the vein of Labbe. The only thing that you don't want to do, is to scan too early, i.e. HYPOPLASTIC LEFT TRANSVERSE, 1 doctor answered this and 857 people found it useful. Notice the prominent vein of Trolard (red arrow) and vein of Labbe (blue arrow). Firstly yes, the brain angiography would show the transverse sinus stenosis if it was present at that time. 2000;129(2):2546. what does that mean? Our website services, content, and products are for informational purposes only. However, preoperative angiography showed antegrade right transverse flow and poor collateral flow indicating this flow is dependent even in subtotal occlusion. Colonoscopy: one 4mm polyp in the sigmoid colon. All authors have no affiliations with or involvement in any organization or entity with any financial interest, or non-financial interest, in the subject matter or materials discussed in this case report. Normally veins are slightly denser than brain tissue and in some cases it is difficult to say whether it is normal or too dense. This prevents blood from draining out of the brain. Anatomic Variation of the Lateral Sinus in Patients With Idiopathic Intracranial Hypertension: Delineation With Black-Blood Contrast-Enhanced MRI. Thrombus appears as prominent hypointense on susceptibility-weighted images [23] and T2*-weighted conventional gradient-echo images [24]. This chain of events is part of a stroke that can occur in adults and children. Bilateral periventricular chronic small vessel ischemic changes. HIGHLIGHTS who: Jia Jia from the (UNIVERSITY) have published the paper: Cerebrovascular intervention therapy worked positively in one patient with severe cerebral venous sinus thrombosis due to hyperthyroidism: a case report and review of the literature, in the Journal: (JOURNAL) what: The authors report a case of severe CVST in whom conventional anticoagulants did not Cerebrovascular . Therefore, headache in isolation was not considered sufficient to diagnose elevated ICP. September 2002 Radiology, 224, 788-789. by Colin S. Poon et al It affects about 5 people in 1 million each year. It is a difficult diagnosis because of its nonspecific clinical presentation and subtle imaging findings. Last medically reviewed on January 20, 2018, The size and shape of the frontal sinus can vary from person to person. Here the sagittal T1-weighted image demonstrating the empty sella (arrow). On the contrast enhanced T1 images on the left there is an area of low signal intensity within the enhancing transverse sinus. Friedman DI, Liu GT, Digre KB. 2b). Hypoplasia of the left sigmoid and transverse sinuses, What does tortuosity of sigmoid colon mean. 1bd). The draining, The maxillary sinus is one of the four paranasal sinuses, which are sinuses located near the nose. Torcular, transverse, and sigmoid sinus meningiomas. Sumi, K., Otani, N., Mori, F. et al. This condition may also be called cerebral sinovenous thrombosis. NO, HO and AY revised the manuscript and contributed to the concept of the manuscript. Dr. Hiep Le answered Nephrology and Dialysis 44 years experience https://doi.org/10.1001/archneur.1986.00520050089032. Another typical venous infarction is due to thrombosis of the vein of Labbe. Arachnoid granulations are small protrusions of the arachnoid through the dura mater. In the differential diagnosis we also should include a venous infarct in the territory of the vein of Labbe. the jugular foramen is dimunitive in size? On the left there is abnormal high signal as a result of thrombosis (red arrow). An orange outline encloses an area of 51.3 mm2. PubMed Central What does congenital hypoplasia of the right vertebral artery mean? Observation of the inside of the dura found no tumor on the inner layer of the dura or arachnoid membrane. On the left reconstructed sagittal CT-images in a patient with bilateral parasagittal hemorrhage due to thrombosis of the superior sagittal sinus. The diagnosis is bilateral infarctions in the basal ganglia due to deep cerebral venous thrombosis. Normal structures in the intracranial dural sinuses: delineation with 3D contrast-enhanced magnetization prepared rapid acquisition gradient-echo imaging sequence. Br J Neurosurg. The patient was initially negative about the surgery, but finally, she was glad to receive the surgery. Here a patient with a peripheral intracerebral hematoma. This is a direct sign of thrombosis and the next step is a CECT, which confirmed the diagnosis (not shown). One had undergone a formal ophthalmologic evaluation in which papilledema was ruled out. We describe a rare case of intracranial hypertension caused by meningioma located inside the dominant sigmoid sinus. This is unlike in an arterial infarction in which there is only cytotoxic edema and no vasogenic edema. In these cases a contrast enhanced scan is necessary to solve this problem. There is a combination of vasogenic edema (red arrow), cytotoxic edema and hemorrhage (blue arrow). Continue with the phase contrast images. This distance was chosen because the transverse sinus is most nearly perpendicular to the sagittal plane in this location. October 2006 RadioGraphics, 26, S19-S41, by J. Linn et al 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. BMC Neurology The clue to the diagnosis in this case is seen on the contrast enhanced image, which nicely demonstrates the filling defect in the sigmoid sinus (blue arrow). The most frequently thrombosed venous structure is the superior sagittal sinus. 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.

JRSM Volume 93, Number 5 Pp. Six patients had hypoplastic contralateral venous sinuses. Control chronic health conditions, such as diabetes. it is normal. CT-venography is a simple and straight forward technique to demonstrate venous thrombosis. The summation of the left and right total outflow cross-sectional area was similarly affected. diverticulitis in the transverse colon and in the left colon. 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. Do you have any symptoms? Hypoplasia or aplasia of TS is a common anatomical variation, right TS is dominant in 61 [percnt] of cases. 857 Views v. Answers . Children and adults have different risk factors for CVST. Results: The risk for this kind of stroke in newborns is greatest during the firstmonth. We expected development of collateral flow and improvement of ICP, but unfortunately imaging showed no change. On a routine non-enhanced MR or CT you should think of the possibility of venous thrombosis when you see: Direct visualization of a clot in the cerebral veins on a non enhanced CT scan is known as the dense clot sign. Farb RI, Vanek I, Scott JN, Mikulis DJ, Willinsky RA, Tomlinson G, et al. The authors recognize that a limiting factor of this study is the small sample size, including a solely pediatric cohort. There is thrombosis of the superior sagittal sinus (red arrow), straight sinus (blue arrow) and transverse and sigmoid sinus (yellow arrow). On the other hand, identifiable secondary causes included venous thrombosis [14] or tumor. The difference in the occurrence of elevated ICP in patients with and without hypoplastic draining sinuses was obtained by using the Fisher exact test. All authors have read and approved the final version of the manuscript. Maiuri F, Di Martino G, Vergara P, Mariniello G. Meningiomas of the transverse--sigmoid sinus junction area. Leach et al9 reported asymmetric transverse sinuses in up to 49% of cases. Disclaimer. As a result, blood cells may break and leak blood into the brain tissues, forminga hemorrhage. This results in a pulsating, heartbeat-like sound being produced in the vein and picked up by the ear. Imaging tests show areas of blood flow. 8600 Rockville Pike A 39-year-old woman suffered visual dysfunction due to bilateral papilledema. On the contrast enhanced T1-weighted image it is obvious that the sinus fills with contrast and is patent. Purpose: To investigate the imaging characteristics, prevalence, and clinical significance of arachnoid granulations in the transverse and sigmoid venous sinuses. The presence of hypoplastic contralateral venous sinus in the setting of thrombosis of a dominant sinus was associated with elevation of intracranial pressure (83% versus 0%, P = .015). Frequent ophthalmologic assessments including quantitative visual fields were planned. On the far left we see a dense vessel sign on the unenhanced CT. Chronic dural sinus thrombosis can lead to dural arteriovenous fistula formation and to increased CSF pressure. Intracranial hypertension can be caused by impairment of blood flow due to occlusion or severe stenosis of the posterior superior sagittal sinus [4, 5], at the torcular herophili, sigmoid sinus, or only transverse sinus with significant dominance on one side [6,7,8,9,10]. https://doi.org/10.1016/j.jocn.2006.01.006. On the left T2-images during the follow up. Csknyi et al6 reported a case series of 8 patients with otogenic CSVT in whom various treatment approaches were used, including internal jugular vein ligation, anticoagulation, and thrombectomy. Neurology. B, The right sinus area is 6.2 mm2. It is more common than previously thought and frequently missed on initial imaging. It is seen in only one third of cases. Skull metastasis of Ewing's sarcoma--three case reports. Cerebrovascular diseases (Basel, Switzerland). Meningioma is typically a slow-growing tumor, so venous invasion occurs very gradually. Her medical and family history was unremarkable, and no evidence of infection was found including sinusitis, otitis media, and mastoid cellulitis. Hypoplasia of the left transverse sinus is a well-known anatomical variation. Arch Neurol. https://doi.org/10.3174/ajnr.A2130. Bring someone with you to help you ask questions and remember what your provider tells you. Article World Neurosurg. In CSVT and venous backpressure, parenchymal injury can occur secondary to vasogenic and cytotoxic edema and possible hemorrhagic venous infarction, which can cause substantial morbidity and mortality. Brain herniations into arachnoid granulations: about 68 cases in 38 patients and review of the literature. She was not taking any medication, including oral contraceptives or hormonal agents. Papilledema confirmed on ophthalmologic assessment was used as our noninvasive criterion standard to diagnose elevation of ICP. Neurosurg Focus.

The post-thrombotic complications, such as the development of pseudotumor cerebri and papilledema, can cause long-term morbidity as well.3. Meningiomas can be classified according to the degree of sinus invasion [25]: Type I, lesion attachment to the outer surface of the sinus wall; Type II, tumor fragment inside the lateral recess; Type III, invasion of the ipsilateral wall; Type IV, invasion of the lateral wall and roof; and Types V and VI, complete sinus occlusion with or without one wall free. Indian J Radiol Imaging. No clinical significance could be given to the existence of any of these arachnoid granulations. At this point in its course the sinus meets with the internal jugular vein. Of the 8 patients in this series, 6 underwent anticoagulation for a variable number of months. The right, In male anatomy, the corpus spongiosum of penis is a mass of erectile tissue that lies along the underside of the penis and is located below the pair. Hypoplastic and sigmoid sinuses noted. Epub 2021 Feb 26. This question is for testing whether or not you are a human visitor and to prevent automated spam submissions. The right transverse and sigmoid sinus,as well as internal jugular vein are diminutive in caliber, likely congenitally hypoplastic,particularly in the absence of secondary findings of venous sinus thrombosis. The frontal sinuses develop as a person ages, reaching full size after 20 years. . In the present case, the lesion appeared isointense on T1-weighted images with homogeneous enhancement following intravenous administration of gadolinium. Revised diagnostic criteria for the pseudotumor cerebri syndrome in adults and children. Diagnosis and management of cerebral venous thrombosis: a statement for healthcare professionals from the american heart association/american stroke association. Also write down any new instructions your provider gives you. Therefore, our patient was treated with lumbar puncture followed by acetazolamide. By using our website, you consent to our use of cookies. Venous thrombosis leads to a high venous pressure which first results in vasogenic edema in the white matter of the affected area. Of the 6 patients with hypoplastic contralateral draining sinuses, all had signs and symptoms of elevated ICP (vomiting, encephalopathy, diplopia, or sixth cranial nerve palsy). Check for errors and try again. The sinus has a low signal intensity on the T2-weighted image as a result of the intracellular deoxyhemoglobin. These findings and the location in the temporal lobe, should make you think of venous infarction due to thrombosis of the vein of Labbe. 2020 Oct-Dec;30(4):517-520. doi: 10.4103/ijri.IJRI_503_19. On a follow up scan the abnormalities had resolved completely. The transverse and sigmoid venous sinuses that were previously mentioned, run very close to the ear. Continue with the video of the thrombectomy. These tests may be used to diagnose venous sinus thrombosis: Treatment should begin immediately andmust be done in a hospital. There is sparse literature on the implications of venous drainage variants in CSVT. CT venography demonstrated filling defect in the dominant sigmoid sinus indicating venous thrombosis. However at some stage of the thrombus there is intracellular deoxyhemoglobin, which is dark on T2 and mimics flow void. b Right presigmoid craniectomy was performed. Gadolinium-enhanced T1-weighted imaging shows a filling defect in the sinus thrombosis. Most cases of venous invasion remain asymptomatic because of the development of venous collaterals. Disclosures: Robert AveryUNRELATED: Grants/Grants Pending: National Institutes of Health K23 award (Topic: Optical Imaging in Children with Tumors of the Visual Pathway). We judged that improvement due to medical treatment could not be expected, so we planned surgical treatment. CAS Cheyuo C, Rosen CL, Rai A, Cifarelli CP, Qaiser R. Venous manometry as an adjunct for diagnosis and multimodal management of intracranial hypertension due to meningioma compressing sigmoid sinus. SY and FM contributed to the obtainment and interpretation of the clinical information. Front Neurosci. All except 2 patients were additionally followed as outpatients to assess their response to therapy and outcome. Current classifications of DAVF focus mainly on the presence of leptomeningeal reflux related to cerebral venous hypertension leading to cerebral venous infarction or hemorrhage. The jugular foramen is dimunitive in size? 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. Epub 2020 Aug 21. 1996 Sep;17(8):1523-32. Where are these sinuses? We investigated methods for improving blood flow by intravascular surgery such as stent placement and percutaneous transluminal angioplasty using a balloon. A thrombus will manifest as absence of flow void. Extracranial intraluminal extension of atypical meningioma within the internal jugular vein. PubMed Central London: Springer; 2009. p. 47383.
