It is often associated with ipsilateral preauricular or submandibular necrotizing lymphadenitis. Background: Parinaud syndrome is a dorsal midbrain syndrome characterized by upgaze paralysis, convergence retraction nystagmus, and pupillary light-near dissociation. Very difficult. Compression of the superior colliculus may result in upward gaze palsy (Parinaud syndrome), and effacement of the cerebral aqueduct may lead to obstructive hydrocephalus (Figure 10. Expiration Date. Stroke is the most common. Parinaud syndrome (dorsal midbrain syndrome), a conjugate upward vertical gaze palsy, may result from a pineal tumor that compresses the midbrain or, less commonly, a tumor or infarct of the midbrain pretectum. It is seen with many eye and neurological problems, including Parinaud syndrome. Patients may complain of difficulty looking up, blurred near vision, diplopia, oscillopsia, and associated neurological symptoms. It is caused by compression of the vertical gaze center at the rostral interstitial nucleus of medial longitudinal fasciculus (riMLF).
