The patient was admitted on December 21, 2020, for approximately 2 months for slow response and memory loss (Figure 1).
Cranial MRI results of the patient, showing multiple lesions in the center of the centrum semiovale with hypointensity on T1-weighted image (A) (arrows), hyperintensity on T2-weighted image (B) (arrows), on FLAIR (C) (arrows), and isointensity on DWI (D). MRI, magnetic resonance imaging.

Brain MRI exhibited multiple lesions in the center of the centrum semiovale, with hypointensity on T1-weighted image (Figure 2A), hyperintensity on T2-weighted image (Figure 2B), on FLAIR (Figure 2C), and isointensity on DWI (Figure 2D).
Imaging examination. Cranial MRA showed no significant intracranial aortic stenosis (A,B). MRV showed thrombosis of the left transverse sinus, sigmoid sinus, and jugular venous bulb (C,D) (arrows). MRA, magnetic resonance angiography; MRV, magnetic resonance venography.

No intracranial aortic stenosis was evident on cranial magnetic resonance angiography (MRA) (Figures 3A,B). On December 26, MRV demonstrated thrombosis of the left transverse sinus, sigmoid sinus, and jugular venous bulb (Figures 3C,D), which was considered CVST.
