A Case of "Flip-Flap" Pattern in Cerebral Neuclear Angiogram

The characteristics of radionuclide brain scan imaging of intracranial lesion are determined, in part, by the rate and quantity of radioactive material in the region of involvement, which is associated with alterations in the blood brain barrier. Findings, noted on the blood flow studies, often serve to direct attention to forthcoming imaging of specific pathological change on the status studies, e.g, carotid artery occlusion and cerebral infarction. We have seen that the 62 year old woman with left side hemiparesis shows typical "Flip-Flap" pattern in brain scan imaging, thought to be due to carotid artery occlusion.
