Walleyed bilateral internuclear ophthalmoplegia (WEBINO) syndrome has mainly been reported in patients with cerebrovascular diseases and multiple sclerosis, but has never been described in patients with neurodegenerative diseases.
To describe a patient with progressive supranuclear palsy (PSP) who presented with WEBINO syndrome.
Case report and review of literature.
A university hospital.
A 72-year-old man began to display akinesia, freezing of gait, postural instability, mild rigidity of the neck, and vertical supranuclear palsy, including downward gaze limitation, at 66 years of age. At 68 years, he started to develop diplopia. At 70 years, he had bilateral medial longitudinal fasciculus syndrome. Later, his eye positions gradually showed alternating exotropia.
A diagnosis of probable PSP was made based on the National Institute of Neurological Disorders and Stroke and the Society for Progressive Supranuclear Palsy criteria. He showed alternating exotropia in the forward gaze, and adduction paresis and monocular nystagmus of the abducted eye in the horizontal gaze, 2 clinical symptoms of WEBINO syndrome.
This is the first reported case of a patient with PSP presenting with WEBINO syndrome. Because bilateral medial longitudinal fasciculus lesions are commonly observed in PSP as clinical and pathological findings, particular attention should be given to WEBINO syndrome in patients with PSP.
