A rare case of cortical venous thrombosis(CVT)

Cortical venous thrombosis is a rare type of cerebrovascular disease that mostly affects children and young adults.superior sagittal sinus thrombosis is the most common type.CVT in children is multifactorial.A prothrombotic risk factor or direct cause is identified in about 85 of cases with sinus thrombosis.The widespread use of neuroimaging now allows for early diagnosis and treatment.CVT is more common than previously thought with favourable outcome and low mortality rate.MRI with T1 T2 ,fluid-attenuated inversion recovery and T2 sequences with MRV are the best diagnostic methods.Heparin is the first line treatment ,but in few cases more aggressive treatments such as local intravenous thrombolysis,mechanical thrombectomy and decompressive hemicraniectomy may be required.
