Two cases of pituitary adenomas invading the cavernous sinus are presented. The technique of radical extirpation of intracavernous tumor is described. Clinical, radiologic and pathologic features diagnostic of invasive adenomas are discussed, as well as alternative treatments. Craniotomy for radical resection is recommended as primary treatment for tumors which can be identified preoperatively as invasive tumors.
