Male, 77 years old, with bilateral ptosis and concern for aneurysmal compression. No restricted diffusion is seen. No evidence of parenchymal edema or mass effect is detected. Scattered foci of FLAIR hyperintensity are seen in the periventricular white matter. No acute intracranial hemorrhage or any abnormal extra axial fluid collections are detected. The ventricles and sulci are mildly prominent compatible with mild underlying parenchymal volume loss.Within the limitations of MRA technique, no evidence of any aneurysm, vascular malformation or obvious high-grade stenosis is seen. At most there may be several scattered mild to moderate areas of vascular narrowing in the right M1 and proximal M2 branches, but this could also be artifactual. Fetal origin of the right PCA is seen.
1.No acute intracranial abnormality.2.No evidence of aneurysm or other specific findings to account for the patient's symptoms.3.Findings are seen which would be compatible with chronic microvascular ischemic disease.
