case_images: MRI of the brain with and without contrast revealed no evidence of an acute ischemic event but did show evidence of dural and cortical venous thrombosis and findings consistent with mastoiditis (see Figure 1).
case_images: MRV of head without contrast demonstrating absence of normal flow-related enhancement within the sagittal, transverse, and left sigmoid sinus suggestive of dural sinus thrombosis. There are small adjacent dural vessels in proximity to these thrombosed sinuses.
