Female, 48 years old, with right arm and leg numbness and tingling. MRI brain:No restricted diffusion is seen. Scattered small foci of T2 hyperintensity are seen within the subcortical white matter of the cerebral hemispheres. No evidence of parenchymal edema or mass effect is seen. No acute intracranial hemorrhage or any abnormal extra-axial fluid collection is detected. The ventricles are normal in size and morphology. A small polyp or mucous retention cyst is seen within the left maxillary sinus.MRA head:No significant intracranial vascular stenosis or occlusion is seen. Fetal origin of the left PCA is noted. The region of the ACOM artery is unremarkable. A small right PCOM artery is demonstrated. No aneurysms are detected within the limitations of technique.MRA neck:No significant stenosis is detected in the carotid vessels of the neck by NASCET criteria. The left vertebral artery is dominant. There may be scattered areas of mild narrowing within the right vertebral artery though this could also be artifactual. No significant or high-grade stenosis is suspected.
1.No evidence of acute ischemia or any other definite acute intracranial abnormality.2.Scattered small foci of white matter T2 hyperintensity are seen, a nonspecific finding which could reflect microvascular ischemic disease, vasculitis, demyelination or migrainous lesions among other possibilities.3.No significant vascular stenosis is detected in the head of the neck.
