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.
在蝶鞍区存在任何“扩张性病变”时，必须记住，在1%的病例中可能存在假性肿瘤性动脉瘤。在许多病例中，无论是临床研究，还是蝶鞍区的X线和断层扫描检查，都无法区分动脉瘤和垂体瘤。只有颈动脉造影在进行双侧检查（单侧压迫不够）的情况下才能明确诊断。因此，这种检查将是系统性的，特别是在那些考虑经蝶窦途径处理蝶鞍区扩张性病变的病例中。
