Symptomatic palatal tremor is not limited to the activity of guillain-mollaret triangle: A functional magnetic resonance imaging case study
Abstract
A 57-year-old man was admitted to our clinic because of speech and swallowing disorder for six months. Palatal tremor and left upper extremity myorhythmia appeared on examination. Magnetic resonance imaging showed hypertrophic olivary degeneration, dentate pathology, Wallerian degeneration, and left parietal cystic encephalomalacia. Functional magnetic resonance imaging study of the brain showed prominent activation on the bilateral globus pallidus and thalamus. We suggest that involuntary movements were introduced by the nuclei of the basal ganglia as a result of olivary dysinhibition.
Özet
Elliyedi yaşında erkek hasta altı aydır olan konuşma ve yutma zorluğu nedeni ile kliniğimize başvurdu. Muayenede ritmik palatal tremor ve solda üst ekstremite kaslarında miyoritmi görüldü. Beyin manyetik rezonans görüntüleme çalışmasında oliver çekirdekte hipertrofik dejenerasyon, dentat çekirdek patolojisi, Wallerian dejenerasyon ve sol parietal hemisferde kistik ensefalomalazik alan görüldü. Fonksiyonel manyetik rezonans görüntülemede her iki globus pallidus ve talamusta belirgin aktivasyon tespit edildi. Bu olgu çalışmasından elde edilen sonuçlar; palatal tremorda görülen istemsiz hareketlerin olivar çekirdeğin disinhibisyonu sonucu bazal çekirdekler tarafından oluşturulduğunu düşündürmüştür.
