[A case of post-infectious wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) syndrome].
The patient is a 72-year-old man who had tonsillitis and underwent incision on March 6, 1998. He complained headache and nausea from March 10 and double vision from March 12. He was admitted to our hospital on March 14. Neurological examination on March 18 revealed bilateral internuclear ophthalmoplegia with exotropia (WEBINO), bilateral ptosis and disturbance of convergence. Lumbar puncture revealed moderately elevated protein (46 mg/dl) with normal pressure and cells. The T2-weighted images of head MRI showed multiple high intensity lesions in anterior commissure and right pons. After he was treated with methylprednisolone, his headache and ptosis disappeared. The lesion in anterior commissure on MRI disappeared also. But WEBINO remained at the time of discharge. WEBINO syndrome is caused by lesion of pons and midbrain. The most common cause of bilateral internuclear ophthalmoplegia is multiple sclerosis in the European and American countries, but the frequency of vascular origin is higher in Japan than in the European and American countries. All the cases of WEBINO syndrome reported in Japan are vascular origin. This is the first case of WEBINO syndrome not of vascular origin.
