Year 2023, Volume: 5 Issue: 1, 49 - 52, 01.03.2023
https://doi.org/10.38175/phnx.1124304

Abstract

Bir buçuk sendromu, ipsilateral medial longitudinal fasikül ve 6. kraniyal sinir çekirdeği ve/veya paramedian pontin retiküler formasyonu içeren tek taraflı bir lezyonu ifade eder. Sekiz buçuk sendromu ise bir buçuk sendromu ile ipsilateral 7. kraniyal sinir felcinin birlikte görüldüğü bir klinik durumdur. Bu nadir tablolar ponsun tegmentumuna yerleşik lezyonlardan kaynaklanır. Burada; ponsta sırasıyla iskemik infarktüs ve hemorajisi olan bir buçuk ve sekiz buçuk sendromlu iki olguyu sunduk.

Two Rare Presentations of Pontine Lesions: One-And-A-Half Syndrome and Eight-And-A-Half Syndrome

Abstract

One-and-a-half syndrome refers to a unilateral lesion involving the ipsilateral medial longitudinal fascicle and the 6th cranial nevre nucleus and/or the paramedian pontine reticular formation. Eight-and-a-half syndrome is a syndrome in which one-and-a-half syndrome and ipsilateral 7th cranial nevre palsy are seen together. These rare conditions result from limited lesions of the pontine tegmentum. We presented two cases with one-and-a-half and eight-and-a-half syndromes with ischemic infarction and hemorrhage in pons, respectively.
