A review of carotid cavernous fistula including diagnosis and evaluation by nuclear medicine angiography.

The various causes and differential diagnosis of carotid cavernous fistula are discussed as well as the description of the use of radionuclide angiography in the diagnosis and evaluation of patients with carotid cavernous fistulas. Radionuclide angiography has proven extremely useful in the diagnosis and follow-up of patients with carotid cavernous fistulas. The procedure is of maximum benefit in situations where repeat studies are required at frequent intervals. Five cases are described in which the nuclear medicine technique was instrumental in primary diagnosis and follow-up.
