An 84-year-old female presented with bilateral giant intracavernous carotid artery aneurysms manifesting as right total ophthalmoplegia and trigeminal nerve paresis. Computed tomography and magnetic resonance imaging showed the two aneurysms as one fused mass, so the initial diagnosis was a parasellar tumor occupying the bilateral cavernous sinuses. The correct diagnosis required cerebral angiography. Considering her age, no surgical or interventional treatment was given. Eight months later, her right eye movement partially recovered and she had no further symptoms. There was no definite causative factors other than aging in this case.
