We present a 4-year-old child who suffered bilateral third nerve palsies secondary to bilateral giant saccular cavernous carotid artery aneurysms. Endovascular treatment was performed by means of direct endosaccular aneurysm occlusion on the right side and parent vessel occlusion on the left, using mechanically detachable coils. No complication occurred during or after the procedure. The bilateral third nerve palsies resolved over 3 months. Follow-up angiography at 1 year is presented.
