Abstract
The eight-and-a-half syndrome is a one-and-a-half syndrome [conjugated horizontal gaze palsy and internuclear ophthalmoplegia (INO)], plus an ipsilateral cranial nerve seventh (CN VII) palsy. This rare syndrome is caused by the pontine tegmentum's lesions involving the abducens nucleus, the ipsilateral medial longitudinal fasciculus (MLF), and the facial colliculus. In this case, we report a 68-year-old male patient admitted to our hospital with binocular horizontal diplopia later diagnosed with the eight-and-a-half syndrome. Although the eight-and-a-half syndrome is rare, it should be kept in mind with patients presenting diplopia and peripheral facial palsy simultaneously.
Özet
Sekiz buçuk sendromu, bir buçuk sendromu [konjuge yatay bakış felci ve internükleer oftalmopleji (INO)], artı ipsilateral kraniyal sinir yedinci (CN VII) felcidir. Bu nadir sendrom, abdusens nükleusu içeren, ipsilateral medial longitudinal fasciculus (MLF) ve fasiyal kollikulusu tutan pontin tegmentum lezyonları sebebiyle meydana gelir. Bu olguda binoküler horizontal diplopi ile hastanemize başvuran ve sonrasında sekiz buçuk sendromu tanısı alan 68 yaşında bir erkek hastayı sunmaktayız. Sekiz buçuk sendromu nadir olmakla birlikte, aynı anda hem diplopi hem de periferik yüz felci olan hastalar da akılda tutulmalıdır.
