Would recommedn have your doctor refer you to a endocrinologist for evaluation and direct your question to some one totally qualified in that field. World Neurosurg. It is a difficult diagnosis because of its nonspecific clinical presentation and subtle imaging findings. Transverse sinus hypoplasia and aplasia are related to intracranial hypertension without papilledema and they are risk factors for chronic migraine. [8] In this article, we present a rare case of right transverse and sigmoid sinus hypoplasia with headache complaint. We describe a rare case of intracranial hypertension caused by meningioma located inside the dominant sigmoid sinus. For potential or actual medical emergencies, immediately call 911 or your local emergency service. Google Scholar. Enter multiple addresses on separate lines or separate them with commas. The inclusion of both adult and pediatric patients might elucidate differences in the incidence of elevated ICP, treatment tendencies, and complications. In their anterolateral portion they receive the inferior anastomotic vein (of Labb). 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. Mittal S, Wu Z, Neelavalli J, Haacke EM. 1e-f). It means that one was born with a small right vertebral, are just normal variants and there is no evidence of venous sinus. Family and friends can describe the symptoms they saw, especially if the person who had the stroke is unconscious. However, various imaging methods such as three-dimensional CT angiography, MR imaging, and cerebral angiography could not identify the precise location inside or outside the sinus. J Clin Neurosci. Unable to process the form. Consistent with these reports, in our cohort, the right transverse sinus was the dominant sinus in 5 of 6 cases. 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]. Where are these sinuses? The MR-techniques that are used for the diagnosis of cerebral venous thrombosis are: Measurements in a patient with hypoplastic right transverse sinus (patient 2). PMC https://www.indianradiologycases.com/MRV sequence here show hypoplastic left transverse sinus. The ratio of the nonthrombosed-to-thrombosed-side cross-sectional area is 0.60. The maxillary sinus is the largest of the paranasal, The nasal cartilages provide structure and support to the nose. Absence of normal flow void on MR (2)The images on the left show abnormal high signal on the T1-weighted images due to thrombosis. 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).

Anatomic variations in cerebral venous development exist, which may influence the ability to appropriately regulate venous drainage from the head and subsequently increase the risk of developing elevated intracranial pressure (ICP), especially in patients with CSVT. The tumor (asterisk) is located inside the sigmoid sinus. 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. Slight deterioration of the bilateral papilledema was noted 6months later. Hypoplasia or total aplasia of the sigmoid sinus is usually seen on the left side. Venous thrombosis leads to a high venous pressure which first results in vasogenic edema in the white matter of the affected area. On the contrast enhanced T1-weighted image it is obvious that the sinus is filled with thrombus. This is seen in thrombosis of the superior sagittal sinus, straight sinus and the internal cerebral veins. Noncontrast computed tomography (CT) revealed no intracranial space-occupying lesions or hydrocephalus except an asymptomatic arachnoid cyst of the left middle fossa (Fig. https://doi.org/10.2176/nmc.39.946. Indian J Radiol Imaging. Bilateral periventricular chronic small vessel ischemic changes. While headache can be a symptom of ICP, other confounding causes of headache such as trauma and mastoiditis were present in much of our patient cohort. The ratio is 0.10. 1997 Jan-Feb;21(1):1-5. doi: 10.1016/0899-7071(95)00093-3. Early aggressive medical and surgical therapy to eradicate the underlying infection in cases of otogenic CSVT, in combination with systemic anticoagulation to prevent thrombus extension and promote recanalization, can lead to favorable outcomes with minimal adverse events.
