Presentation
Headache and vomiting.
Patient Data
Bilateral thalamic hyper-T2/FLAIR signal intensity with blooming artifacts on echo gradient sequence denoting swollen/edematous bilateral thalami with mild hemorrhagic transformation, secondary to venous infarction caused by the extensive venous thrombus involving the straight and right transverse sinuses.
Case Discussion
A previously healthy patient presented to the emergency department complaining of headaches and dysarthria. A CT scan was done and showed no significant abnormality. A laboratory workup showed an incidental positive PCR for COVID-19 infection.
On day 2 of admission, a follow-up brain MRI/MRV was performed. It showed bilateral thalamic venous infarction caused by the extensive venous thrombus involving the straight and right transverse sinuses.
