Children with unilateral CSVT and contralateral venous hypoplasia should be evaluated and followed closely for development of elevated ICP. This prevents blood from draining out of the brain. Accurate diagnosis of subtypes of transverse sinus (TS) hypoplasia requires more expensive methods like magnetic resonance (MR) imaging. Normal structures in the intracranial dural sinuses: delineation with 3D contrast-enhanced magnetization prepared rapid acquisition gradient-echo imaging sequence. 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. In this special Missouri Medicine report, doctors examine advances in diagnosis and treatment of this devastating and costly neurodegenerative disease.

The clinical manifestations and radiological findings indicated venous thrombosis. A thrombus will manifest as absence of flow void. This distance was chosen because the transverse sinus is most nearly perpendicular to the sagittal plane in this location. These findings and the location in the temporal lobe, should make you think of venous infarction due to thrombosis of the vein of Labbe. The dosing of LMWH was adjusted according to the patient's weight and liver function . 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.

Mazur MD, Cutler A, Couldwell WT, Taussky P. Management of meningiomas involving the transverse or sigmoid sinus. This results in a pulsating, heartbeat-like sound being produced in the vein and picked up by the ear. 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. This is a direct sign of thrombosis and the next step is a CECT, which confirmed the diagnosis (not shown). A 39-year-old woman suffered visual dysfunction due to bilateral papilledema. When the hemorrhagic component of the infarction is large, it may look like any other intracerebral hematoma with surrounding vasogenic edema. the jugular foramen is dimunitive in size? Contrast-enhanced MR venography has the disadvantage that you need to give contrast, but has less pitfalls. The subtle density in the area of the left transverse sinus (arrow) is the key to the diagnosis. The tumor was directly observed after retraction of the dura and sinus.
