Visual changes and word finding difficulties with headache in the setting of pregnancy. MRI of the brainNo diffusion weighted abnormalities are appreciated.The CSF spaces are appropriate for the patient's stated age with no midline shift. No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.MRA brain:Antegrade flow is present in the distal internal carotid arteries, the distal vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries.There is no evidence for intracranial aneurysm or cerebrovascular occlusion.The anterior communicating artery is identified. The A1 segments are similar in size. The right posterior communicating artery is medium size whereas the left PCOMA is small. The vertebral arteries are similar in size.MRV brain:The dural venous sinuses are patent. Straight sinus, internal cerebral veins and basal veins are identified and appear patent.
1.No evidence for cerebrovascular occlusive disease.2.No evidence for intracranial aneurysm.3.MR venogram of the brain is within normal limits.4.No evidence for intracranial mass lesion or cerebral infarction.
