Abstract :

Oculomotor nerve paresis (ONP) with subarachnoid hemorrhage (SAH) occurs usually when oculomotor nerve is compressed by growing or budding of posterior communicating artery (PcoA) aneurysm. Midain injury, increased intracranial pressure (ICP), or uncal herniation may also cause it.2 We report herein a rare case of ONP associated with SAH which was caused by anterior communicating artery aneurysm rupture.3 A 63 year old female patient presented with multiple episodes of vomiting and sudden onset severe headache for the past 4 days. She was found to have anterior communicating artery aneurysm rupture leading to WFNS grade 1 SAH. She also complained of diplopia and ptosis and was found to have left third nerve palsy. Remaining clinical examination findings were normal.
