The Eye Opener: Finding and Targeting the Midbrain Lesion

ABSTRACT

Lesions of the central nucleus of the third cranial nerve in midbrain leads to bilateral ptosis. We present a case of a 14 year old boy, who was found to have B/L non-correctable ptosis and medial rectus palsy. There was a ring enhancing lesion in the midbrain in contrast MRI which resolved with treatment. The case exemplifies that bilateral ptosis results from the central nucleus involvement of third nerve which has bilateral innervation.
