This is a 50-year-old woman presenting with a partial 3rd nerve palsy (mild pupil involvement), partial 6th nerve palsy, and no clear incyclotorsion with downgaze, suggestive of additional 4th nerve palsy, all on the left. With compressive lesions involving the 3rd nerve, often aberrant regeneration develops - in this case, injury to the left 3rd nerve miswiring so that some of the fibers destined for the left medial rectus instead went to the left levator palpebrae. When adducting the left eye, the eyelid elevated slightly. There was no evidence of aberrant regeneration causing any pupillary or motility findings.
