Initial MRI brain of our patient with and without contrast showed right frontal hyperintensity on FLAIR (a) with corresponding area on gradient echo (b), suggestive of a small intraparenchymal hemorrhage. GRE also showed decreased signal of two frontal cortical veins (b). Sagittal T1 imaging (c) revealed heterogeneous signal of the superior sagittal sinus. Postcontrast images were remarkable for a filling defect with direct visualization of the thrombus (d) in the superior sagittal sinus.

Her MRI and MRV are shown below in Figures 1 and 2, respectively.
MRV of the head without contrast revealed a lack of flow in the superior sagittal sinus (a), as well as right transverse and sigmoid sinuses (b).

Her MRI and MRV are shown below in Figures 1 and 2, respectively.
Follow-up MRV of the head 5 months after diagnosis noted minimal residual thrombus in the superior sagittal sinus (a), with resolution of the thrombus in the right sigmoid, and transverse sinuses (b).

At that time repeat MRV was notable only for a small residual thrombus in the superior sagittal sinus, as seen in Figure 3.
