title: Giant drusen (astrocytic hamartoma) of the optic nerve seen with computerized axial tomography.
abstract: An EMI scan (computerized axial tomography) performed on a 75-year-old man with giant drusen (astrocytic hamartoma) of the left optic nerve clearly revealed a dense localized mass at the distal termination of the left optic nerve. The EMI scan proved to be an accurate, noninvasive technique for neuro-ophthalmologic diagnosis.
