- Pupil Involving 3 rd Nerve Palsy Aneurysm at junction of
posterior communicating artery and internal carotid artery Aneurysm
at junction of posterior communicating artery and internal carotid
artery Partial pupil involvement in 25-47% of patients with
posterior communicating artery aneurysms Partial pupil involvement
in 25-47% of patients with posterior communicating artery
aneurysms

- Pupil Sparing 3 rd Nerve Palsy Microvascular ischemia most
common cause Microvascular ischemia most common cause pupillary
involvement in up to 20% (typically mild 1mm anisocoria) may
present with pain diplopia improves within 3 months Aberrant
regeneration Aberrant regeneration common after trauma or
compression by aneurysm or tumor NOT WITH MICROVASCULAR

- 3 rd Nerve Palsy Rare causes Rare causes tumor, inflammation
(sarcoid), vasculitis, infection (meningitis), infiltration
(lymphoma, carcinoma), trauma (pupil involving) Divisional
Divisional lesion of anterior cavernous sinus or possibly posterior
orbit Children Children ophthalmoplegic migraine ophthalmoplegia
develops days after onset of head pain
