case_images: T1 + Gd sequence (gadolinium), axial section. Yellow arrows demonstrate hyposignal area on the right transverse sinus topography - suggestive of thrombosis

case_images: CT scan did not reveal signs of ischemic or hemorrhagic stroke. Craniocerebral MRI angiography were ordered, detecting the presence of thrombosis in the right sigmoid sinus and the confluence between the transverse sinus and the superior sagittal sinus without intraparenchymal ischemic signs (Figures 1 and 2).
case_images: 3D TOF sequence (RM venography) - Arrows demonstrate the absence of flow at the level of transverse sinus on a distance of 30 mm in the middle third portion, close to the sinus confluence
