Post traumatic isolated ipsilateral oculomotor nerve palsy: An uncommon presentation

Abstract

The common causes of isolated third nerve palsy are microvascular infarction, intracranial aneurysm, diabetes, hypertension and atherosclerosis. Here we are presenting a case of 26-year female presenting with a history of head injury two months back. She presented with ptosis on the left side. On computed tomography, a large left-sided chronic subdural hematoma with significant midline shift was found. Isolated ipsilateral third nerve palsy is a rare presentation with unilateral chronic subdural hematoma. Improvement in ptosis after surgery indicate a good neurological outcome.
