title: [Arteriography in pituitary tumors. Pseudotumoral aneurysm].
abstract: In the presence of any "expansive process" of the sellar region, one must recall that in I % of the instances there may be the possibility of a pseudo-tumoral aneurysm. In a number of cases, neither the clinical study, nor the roentgenologic and tomographic balance of the sellar region, will allow to differentiate an aneurysm and a pituitary tumor. Only the carotid arteriography makes possible a diagnosis of certainty under the condition to make a bilateral study (compression being insufficient). This kind of investigation will therefore be systematic, particularly in those cases in which a sphenoid route of access is considered for the management of the expansive process of the sellar region.
