29-year-old female with weeks pregnant and is having worsening of baseline HA and hx of miscarriage; evaluate for cerebral venous thrombosis. MRI Brain:There is no evidence of intracranial hemorrhage, mass, or acute infarct. The brain parenchyma and pituitary gland appear unremarkable. The ventricles and basal cisterns are normal in size and configuration. There is no midline shift or herniation. The major cerebral flow voids are intact. The orbits, skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable.MRA Brain: Somewhat limited exam secondary to motion. The intracranial internal carotid arteries demonstrate no significant stenosis. The middle and anterior cerebral arteries are also patent. The vertebral arteries, basilar artery, and posterior cerebral arteries are patent with no significant stenosis. No evidence of aneurysms or vascular malformations.MRA Neck: There is loss of signal involving the origins of the vertebral and carotid arteries in the neck but this is secondary to technique. The visualized common carotid arteries and cervical internal carotid arteries are normal in course and caliber. There is no evidence of stenosis or occlusion.MRV Neck:Limited exam secondary to lack of intravenous contrast. The dural venous sinuses and visualized deep cerebral veins show normal flow related enhancement compatible with patency. There is no evidence of venous thrombosis.
Within the limitations of the exam described above, the brain and vasculature of the brain and neck appear within normal limits.
