Abstract :

Introduction: Cereal Venous Sinus Thrombosis (CVST) is an uncommon condition. It is one of the causes of the stroke with uncertain pathological and physiological properties and differs from arterial strokes. MR venography may be performed without the use of a contrast agent using the time–of–flight (TOF) technique or the phase contrast technique. Aims : To study the extent of venous sinus involvement on MRV and associated cereal parenchymal changes on magnetic resonance imaging (MRI) in patients with clinically suspected CVST. Material And Methods: All the patients with clinical indication of CVS thrombosis referred to the Department of Radiodiagnosis for scanning on 1.5T SIEMENS (Magnatom Avanto). Every effort was made to make sure of high–quality scans and to avoid artefacts. CSF examination, blood parameter, other radiological investigation and histopathological reports were reviewed and recorded according to the provisional diagnosis. Results: Out of 44 studied cases 29 (65.9%) patients showed no altered signal intensity areas. Isointense areas were found in 9 (20.4%) cases whereas hyperintense and hypointense signal areas were found in 5 (11.3%) and 1 (2.27%) cases respectively. The sensitivity, 95% confidence interval and positive predictive value of T1 weighted imaging for the diagnosis of CVT was found to be 34.09%, 20.49% to 49.92% and 100%. Conclusion: We demonstrate the role of MR venogram, with different sequences of MRI i.e. T1WI, T2WI, DWI with ADC mapping and susceptibility weighted imaging in early and accurate diagnosis of CVST, as its timely diagnosis has got an impeccable prognosis.
