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. Various image inspections such as three-dimensional CT angiography, magnetic resonance imaging, and cerebral angiography demonstrated a small 2.5-cm lesion causing subtotal occlusion of the dominant right sigmoid sinus. Idiopathic intracranial hypertension (IIH) is a condition associated with increased ICP in the absence of intracranial pathological findings such as mass lesions or cerebral edema [11]. Cerebral venous sinus thrombosis occurs when a blood clot forms in the brain's venous sinuses. The subtle density in the area of the left transverse sinus (arrow) is the key to the diagnosis. Although these findings are often present on initial scans, they are frequently detected only in retrospect. Her cranial nerves were intact. At first impression this looks like an empty delta sign. She had no diplopia, weakness, ataxia, or sensory disturbance. Farb RI, Vanek I, Scott JN, Mikulis DJ, Willinsky RA, Tomlinson G, et al. The final diagnosis, however, is usually made based on how the blood is flowing in the brain. 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. This is seen in thrombosis of the superior sagittal sinus, straight sinus and the internal cerebral veins. Objective: To examine the association between hypoplasia of the transverse sinus and ipsilateral transverse sinus (TS) thrombosis Background: Transverse sinuses (TS) are frequently asymmetric. The cause of IIH is unknown but probably involves obstruction of the cerebral venous outflow [12, 13]. On the left a patient with a subcortical area of high signal intensity. These can increase your risk for blood clots. PubMed f Conventional angiogram, venous phase, showing the mass lesion apparently located at the inner sinus wall mimicking venous thrombosis.
