CT diagnosis is very accurate in localizing supra-sellar cistern tumors but is useless in localizing intrasellar tumors, especially microadenomas, which do not involve the suprasellar cistern. Although the appearance of tumors of each type vary from each other most have certain typical characteristics. When CT findings are considered with the clinical and X-ray manifestations, the character of more than half of the tumors can be determined with fair accuracy. A protocol on selecting the radiologic methods for sellar region tumors is suggested.
