BAZİLER ARTER TROMBOZUNA BAĞLI PONS İNFARKTI SONRASI GELİŞEN PATOLOJİK GÜLME OLGUSU

Abstract

Patolojik gülme, uygun duygu durumu veya uyaran olmaksızın ortaya çıkan ve kontrol edilemeyen gülme ataklarıdır. Serebrovasküler hastalıklarda ortaya çıkabilen bir durumdur. 60 yaşında erkek hasta sağa konjuge bakış parezisi, sol fasyal parezi, 9 ve 10. cranial sinir parezisi ve sağ hemiparezi bulguları ile başvurdu. Kranial MR anjiografide dolikoektatik baziler arter ve midbaziler stenoz saptandı. Hastanın izleminin altıncı ayında patolojik gülme tablosu gelişti. Patolojik gülmenin mekanizmaları tam olarak bilinmese de serebellum ve serebropontoserebellar yolakların düzenleyici fonksiyonları bu fenomeni açıklamada yeni bir alternatif görüş oluşturmaktadır.
