Cerebrovascular accident and abnormal focus of hyperactivity revealed by dynamic study in scintiangioencephalography.

A 75-year-old female was admitted to the hospital for suspicion of a cerebrovascular accident. An important focus of hyperactivity was noted during a dynamic study by scintiangioencephalography, consistent with a highly vascular tumor, but corresponding in fact to a focal transitory hyperfusion with accompanying intense neuronal activity.
