Clinical and imaging characteristics of cerebral venous sinus thrombosis / 临床神经病学杂志

ABSTRACT

Objective To study the clinical and imaging characteristics of cerebral venous sinus thrombosis(CVST).Methods Clinical data of 9 cases with CVST were retrospectively analyzed.Results All patients had headache,nausea and vomiting; 5 patients had epilepsy; 3 patients had focal neurological deficits; 3 patients had fever; 3 patients had palilledema; 3 patients had disturbance of consciousness. CSF examination showed prominent high intracranial pressure, but conventional and biochemical examinations were normal. 8 patients did CT scan, but the diagnosis was not clear. All patients first MRI showed venous sinus and related brain areas long T1 and T2 signal; MRV showed that the involved venoussinus had non-visualized signal. MRI in chronic phase showed slightly higher T1 and T2 signal; MRV showed sinus enhancement.The outline of uncomplete reconalzation was unclear. Conclusions The common high intracranial pressure is unspecific sign and symptom of patients with CVST. CSF examination show that the intracranial pressure is prominent high, but conventional and biochemical examination are normal. MRI can show that the normal flow void of the dural sinus is disappeared, instead of abnormal high or equality intensities. The characters of CVST in MRV are those the blood flow signal of involved venous sinus be disappeared or showed anormalism.
