Abstract: Anterior communicating artery (ACoA) aneurysms may rarely lead to oculomotor nerve palsy. We present here interesting cases in which isolated unilateral adduction paresis mimicking internuclear ophthalmoplegia (INO) was one of the symptoms of suspicious impending ruptured aneurysm of the ACoA. Careful neurologic examination is crucial for early discrimination with INO and oculomotor palsy.
