INTRODUCTION
Primary aberrant regeneration or oculomotor nerve synkinesis is a rare
condition in which cranial nerve III regeneration occurs without a preceding,
acute palsy. It has been typically associated with aneurysms or meningiomas
in the cavernous sinus that do not warrant urgent imaging.1
We describe a patient with primary aberrant regeneration caused by an aneurysm
located at the junction of the left posterior communicating (PCOM) and posterior
cerebral arteries, indicating that imaging should not be delayed.
Report of a Case
A 65-year-old woman complained of right eyelid ptosis for 3 years. She
denied diplopia. Her medical history was unremarkable. Her visual acuity was
20/25 OD and 20/20 OS. The eyelid margin to corneal reflex distance measured
2 mm OD and 4 mm OS. Her right pupil was 4 mm and reacted briskly to light.
Her left pupil was 5 mm and did not react to light. No relative afferent pupillary
defect was observed.
