ABSTRACT

Brain scans performed with Tc-99m HEDP in two patients with suspected intracranial lesions showed abnormal uptake characterized by a focal area of accentuated concentration in a region of increased radioactivity. Surgery revealed that the focal uptake represented the attachment of meningioma and the general region of increased activity corresponded to the meningioma itself.
