Female, 45 years old, with transient ischemic attack. Brain MRI:No restricted diffusion is seen. There is no evidence parenchymal edema or mass effect. No findings to suggest intracranial hemorrhage or any abnormal extra axial fluid collection are detected. The ventricular system is normal in size and morphology. Again seen is crowding at the level of the foramen magnum with cerebellar tonsillar ectopia, right side more than left, similar to prior.Brain MRA:No significant intracranial vascular stenosis or occlusion is observed. No aneurysm or vascular malformation is detected.Neck MRA:Mild mural irregularity at the carotid bifurcations is seen which could reflect either mild atherosclerotic disease or imaging artifact (to which noncontrast neck MRA images are particularly susceptible). Otherwise, no significant stenosis is detected by NASCET criteria within the carotid or vertebral vasculature.C-spine MRI:Alignment is anatomic. Vertebral body height and morphology are within normal limits. No concerning marrow replacement or marrow edema is seen. The visualized spinal cord demonstrates normal signal intensity and morphology throughout. No epidural process is suspected.C2-3: Unremarkable. C3-4: Mild facet hypertrophy. Left uncovertebral hypertrophy with slight left foraminal osteophytic spurring. Moderate left foraminal narrowing. No significant interval changes.C4-5: Unremarkable. C5-6: Mild facet hypertrophy. Mild uncovertebral hypertrophy. No significant spinal canal or foraminal stenosis. No significant interval changes.C6-7: Mild facet hypertrophy. Mild posterior disc-osteophyte complex formation with a small central extrusion. No significant generalized spinal canal stenosis. Mild left foraminal narrowing. No significant interval changes.C7-T1: Mild facet hypertrophy. Mild posterior disc-osteophyte complex formation with a small central disc protrusion which appears similar to prior. No significant spinal canal or foraminal stenosis. No significant interval changes.
1.No evidence of acute ischemia or any other significant intracranial abnormality. Cerebellar tonsillar ectopia is unchanged.2.No significant vascular abnormality on either the brain or neck MRA. Mild irregularity at the carotid bifurcations may represent imaging artifact or perhaps mild atherosclerotic disease.3.Mild degenerative disc disease is again seen without significant interval change and with no areas of high-grade spinal canal stenosis. The spinal cord is unremarkable.
