Parkinson’s syndrome – The syndrome within a syndrome – A case report

Abstract

Horner’s syndrome is caused by damage to the sympathetic pathway anywhere along its course. The unique association of the sixth nerve palsy with ipsilateral Horner’s syndrome has a localizing value, known as Parkinson’s syndrome. The patient described here had left ptosis, miosis of pupil, and abduction limitation on left gaze. A diagnosis of Parkinson’s syndrome was made. Magnetic resonance angiography confirmed a cavernous lesion. High suspicion is essential for diagnosis of such a variant of Horner’s syndrome.
