Female, 45 years old, with history of TIA in January 2016, now with worsening right-sided weakness, and pain at T9-10, thoracic spine with pressure, possible autoimmune picture. MRI brain:No restricted diffusion is seen. No evidence of parenchymal edema or mass effect is detected. A 2 mm nonspecific focus of T2 hyperintensity is seen within the left superior frontal gyrus. Otherwise, no abnormal parenchymal signal is seen. There are no findings to suggest acute intracranial hemorrhage or any abnormal extra-axial fluid collection. The ventricular system is normal in size and morphology.MRA brain:MRA images are degraded by motion artifact. Within this limitation, no high-grade stenosis is suspected though many areas of the intracranial vessels are not well assessed. The area of the ACOM artery is not well visualized. The PCOM arteries are not clearly seen. The left vertebral artery is dominant. The proximal basilar artery may be fenestrated.MRA neck:No significant stenosis of the carotid vessels is detected by NASCET criteria. Likewise, no significant stenosis of the vertebral vessels is suspected, though evaluation is limited by motion artifact.Thoracic spine MRI:Image quality is degraded by motion artifact. Within this limitation, the following observations are made. Alignment is anatomic. Vertebral body morphology and signal characteristics are within normal limits. No pathologic marrow enhancement is seen.The spinal cord shows normal signal intensity and morphology throughout. No abnormal parenchymal or leptomeningeal enhancement is detected. No epidural abnormalities are present.The intervertebral disc spaces are preserved. No significant disc bulge or herniation is seen. No spinal canal or foraminal stenosis is noted.
1.Unremarkable evaluation of the brain with no acute abnormality and no specific findings to account for the reported symptoms.2.Within the limitation of motion degradation, MRA images of the brain and neck are unremarkable.3.Within the limitation of motion degradation, MRI of the thoracic spine is unremarkable.
