Presentation
Presented with a viral-like illness including vomiting and fever) followed by sudden unresponsiveness. No past medical/surgical history.
Patient Data
Straight sinus, right transverse and internal cerebral veins hyperdensity consistent with acute venous thrombosis at those locations
Bilateral hypodensity of both thalami in keeping with thalamic venous infarction.
Uniform FLAIR hyper intensity of both thalami corresponding to low signal on T1 and restricted diffusion on DWI consistent with acute ischemia.
MRV MIP reconstructed images demonstrating complete occlusion of right transverse sinus, straight sinus and bilateral inferior cerebral veins consistent with central cerebral venous thrombosis.
Case Discussion
Cerebral venous / dural thrombosis is not commonly seen cause of brain ischemia. It is commonly associated with underlying prothrombotic condition or systemic illness. In this case, the patient had factor III deficiency (which was diagnosed subsequently) and dehydration due to viral infection.
