From: Japanese encephalitis accompanied by cerebral venous sinus thrombosis: a case report
MR imaging of the patient before and after treatment. (A) Axial T2-weighted images showed the swelling of bilateral thalamus. (B) Contrast Enhanced MRI scan revealed sigmoid sinus and transverse sinus filling defect (white arrows), indicating venous thrombosis. (C and D) The MRV scan indicated absence of signal in the bilateral sigmoid sinuses and left transverse sinuses before treatment (blue arrows). (D) Red arrow showed an arachnoid granulation not venous thrombosis in the right transverse sinus. (E, F) The repeat MRV scan demonstrated only a few low signal areas in the left sigmoid sinus after treatment.
