Her cranial nerves were intact. Venous infarction (5) - Edema This is the rare case of small meningioma involving the sigmoid sinus leading to intracranial venous hypertension mimicking venous thrombosis. Syndrome simulating pseudotumor cerebri caused by partial transverse venous sinus obstruction in metastatic prostate cancer. However venous infarctions do have a typical distribution, as shown on the left. A stroke is serious and requires immediate medical attention. Meningiomas. However, preoperative angiography showed antegrade right transverse flow and poor collateral flow indicating this flow is dependent even in subtotal occlusion. 2020 Oct-Dec;30(4):517-520. doi: 10.4103/ijri.IJRI_503_19.

Dense clot sign (3) It is more common than previously thought and frequently missed on initial imaging. Two of these 3 had complications secondary to long-standing ICP, including permanent visual impairment and prolonged sixth cranial nerve palsy. Observation of the inside of the dura found no tumor on the inner layer of the dura or arachnoid membrane. Farb RI, Vanek I, Scott JN, Mikulis DJ, Willinsky RA, Tomlinson G, et al. 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. Saposnik G, Barinagarrementeria F, Brown RD Jr, Bushnell CD, Cucchiara B, Cushman M, et al. Also write down any new instructions your provider gives you. Epub 2021 Jan 13.

No obvious dural tail sign is present. If you have the above symptoms, have someone take you immediately to the emergency room or call 911 for help. The first impression was that this could be a low grade glioma. Large arachnoid granulations involving the dorsal superior sagittal sinus: findings on MR imaging and MR venography. CT venography demonstrated subtotal occlusion of the right sigmoid sinus, caused by a well-defined, homogeneous, hypodense mass. Due to the high venous pressure hemorrhage is seen more frequently in venous infarction compared to arterial infarction. Contrast-enhanced MR venography has the disadvantage that you need to give contrast, but has less pitfalls. On the far left a FLAIR image demonstrating high signal in the left thalamus. On the left T2-images during the follow up. 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. Outcomes were determined from clinic notes and imaging performed 36 months after hospitalization. BMC Neurol 21, 119 (2021). Liu L, Wu Y, Zhang K, Meng R, Duan J, Zhou C, Ji X. Recognizing these anatomic variations may be important when determining treatment and monitoring protocols for children with CSVT.3 We present a series of pediatric patients with unilateral CSVT involving the transverse/sigmoid sinuses and jugular vein and the influence of an anatomic variation (ie, the structure of the unaffected contralateral venous sinus) on the elevation of intracranial pressure and clinical outcome. Notice that there is some linear density within the infarcted area. How were these noted? Purpose: J Pediatr Neurosci. 1986;43(5):51921. A small left transverse sinus and sigmoid sinus is noted. Five of 6 patients had elevated ICP confirmed by papilledema. AJR 2006; 187:1637-1643, by L K Tsai et al In the early stage there is non-enhancement of the thrombosed vein and in a later stage there is non-enhancement of the thrombus with surrounding enhancement known as empty delta sign, as discussed before. Intracranial hypertension has been associated with a few cases of meningioma secondary to compression of the venous sinus [1,2,3]. Notice the abnormal high signal in the internal cerebral veins and straight sinus on the T1-weighted images, where there should be a low signal due to flow void. Leach JL, Jones BV, Tomsick TA, Stewart CA, Balko MG. AJNR Am J Neuroradiol. She was not taking any medication, including oral contraceptives or hormonal agents. On the source image on the right you can see that there is no hypoplasia (blue arrow). Hypoplastic : It means that the left anterior cerebral artery is smaller than the right side.It is not unusual to have one of these vessels be bigger or dominant th. The sign may be absent after two months due to recanalization within the thrombus. https://doi.org/10.7759/cureus.4953. 2005-2023 Healthline Media a Red Ventures Company. This unusual case suggests that early surgical strategies should be undertaken to relieve the sinus obstruction. Reports with a unilateral transverse and/or sigmoid sinus thrombus were included. 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. Histological examination of the surgical specimen revealed spindle-shaped tumor cells, with narrow rod-shaped nuclei arranged in intersecting fascicles, without mitotic activity, nuclear atypia, or necrosis. 2008 Aug;29(7):1335-9. doi: 10.3174/ajnr.A1093. 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. In the present case, the differential diagnosis after non-contrast CT is venous thrombosis or IIH based on clinical presentation, ophthalmological evaluation for papilledema, and radiological findings of absence of intracranial space-occupying lesions, brain edema, or hydrocephalus. Epub 2020 Aug 21. Vein of Trolard, which is the largest cortical vein that drains into the superior sagittal sinus. 2009;30(2):23252. Alper F, Kantarci M, Dane S, Gumustekin K, Onbas O, Durur I. Continue with the video of the thrombectomy. 1e-f). Mazur MD, Cutler A, Couldwell WT, Taussky P. Management of meningiomas involving the transverse or sigmoid sinus. Pseudotumor cerebri due to partial obstruction of the sigmoid sinus by a cholesteatoma. The MR imaging findings of venous thrombosis are expected to show acute thrombus as isointense on T1-weighted images and hypointense on T2-weighted images, and subacute thrombus as hyperintense on T1- and T2-weighted images. 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. Sindou M. Meningiomas invading the sagittal or transverse sinuses, resection with venous reconstruction. Malekzadehlashkariani S, Wanke I, Rfenacht DA, San Milln D. Neuroradiology. Intracranial hypertension due to meningioma of the unique transverse sinus. A stroke can damage the brain and central nervous system. This unusual case suggests that early surgical strategies should be undertaken to relieve the sinus obstruction. Mariniello G, Giamundo A, Donzelli R, Severino R, Russo C, Elefante A, et al. 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.

On a follow up scan the abnormalities had resolved completely. Yokota H, Noguchi H, Yokoyama K. Epidermoid cyst with Torcular Herophili obstruction and unusual venous drainage. Article Nucl Med Mol Imaging. The presence of a hypoplastic contralateral venous sinus in the setting of thrombosis of a dominant sinus was highly associated with elevation of ICP (83% versus 0%, P = .015). Another typical venous infarction is due to thrombosis of the vein of Labbe. We can conclude that MRI has many false positives and negatives in the diagnosis of venous thrombosis. https://doi.org/10.3171/jns.2006.105.4.514. So please try to relax and do not worry about it.

Time-of-Flight angiography is based on the phenomenon of flow-related enhancement of spins entering into an imaging slice. MeSH Notice the size difference of the jugular foramen. Mittal S, Wu Z, Neelavalli J, Haacke EM. This results in a relative high density of the blood in the sagittal sinus compared to the brain, which simulates a dense clot sign. https://doi.org/10.1212/01.wnl.0000066683.34093.e2. Small residual tumor remained involving the transverse sinus, but the patency was checked immediately by Doppler probe or indocyanine green fluorescence. 2020 Oct;54(5):264-266. doi: 10.1007/s13139-020-00664-5. Please enable it to take advantage of the complete set of features! On spin-echo images patent cerebral veins usually will demonstrate low signal intensity due to flow void. In these cases a contrast enhanced scan is necessary to solve this problem. At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Up to 25% of patients with pulsatile tinnitus may result from boney anomalies of the sigmoid sinus (dehiscence or diverticula) and is likely the single most common cause.

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. A DAVF or dural arteriovenous fistula is an abnormal connection between dural arteries, which are branches of the external carotid with the venous sinuses. SUMMARY: Variations in cerebral venous development can influence the ability to regulate drainage. Check for errors and try again. The tumor was located lateral sigmoid sinus, had invaded the sigmoid sinus, and attached to the sinus wall projected inside the sigmoid sinus. The transverse sinuses exhibit highly variable anatomy, which at times makes imaging evaluation of them, in those with possible dural venous sinus thrombosis, very difficult. By using this website, you agree to our The patients postoperative course was uneventful. Neurological examination found normal consciousness with no abnormalities. If you have had this type of stroke, you may need to avoid certain types of medicines, such as oral contraceptives. The most frequently thrombosed venous structure is the superior sagittal sinus. Venous infarction (4) - Deep cerebral veins California Privacy Statement, London: Springer; 2009. p. 47383. The left and right distal transverse sinus showed an 88% and 86% reduction in mean cross-sectional area, respectively, in patients with IIH compared with controls. Intracranial tumor compressing or invading the dural sinuses including meningioma [1, 4,5,6,7,8,9], solitary fibrous tumor/hemangiopericytoma [15], osteoma [16], osteoblastoma [17], epidermoid cyst [18], metastatic carcinoma [19, 20], Ewing sarcoma [21], and cholesteatoma [22] must be distinguished from venous thrombosis or IIH. https://doi.org/10.4103/jpn.JPN_167_16.
