Association between intracranial aneurysms and pituitary adenomas. AEtiopathogenetic hypotheses.
Of 144 cases of pituitary adenoma operated on in the period 1981-1985, 53 underwent angiography and two of these had an associated intracranial aneurysm. The aetiological hypotheses are viewed in the light of these two cases and of the 60 published cases of this association. The most convincing hypotheses involve mechanical, microcirculatory and hormonal factors. On the hormonal front, GH seems to have a predisposing influence on intracranial aneurysm formation.
