TWO PATIENTS WITH TRANSIENT GLOBAL AMNESIA IN WHICH REPEATED DIFFUSION-WEIGHTED IMAGING REVEALED HIPPOCAMPAL HYPERINTENSITY: CASE REPORTS

Abstract

An episode of temporary memory loss which is recovered within 24 hours is called transient global amnesia. The etiology and triggering factors are unclear but hippocampal lesions may contribute to this condition. Diffusion-weighted magnetic resonance imaging is used to detect these lesions. In this case report, two cases with transient global amnesia who had hippocampal lesions are presented.

TEKRARLANAN DİFÜZYON AĞIRLIKLI GÖRÜNTÜLEMEDE HİPOKAMPAL HİPERİNTENSİTE SAPTANAN İKİ GEÇİCİ GLOBAL AMNEZİ OLGUSU: OLGU SUNUMLARI

Abstract

Geçici global amnezi, 24 saat içinde iyileşen geçici hafıza kaybı ataklarıdır. Etyolojisi ve tetikleyici faktörleri aydınlanmış değildir ancak hipokampal lezyonlar geçici global amneziye katkıda bulunabilir. Bu lezyonları saptamak için difüzyon ağırlıklı manyetik rezonans görüntüleme kullanılır. Bu olgu sunumunda hipokampal lezyonu olan geçici global amnezili iki olgu sunuldu.

Keywords

• Geçici global amnezi
• hipokampus
• difüzyon ağırlıklı manyetik rezonans görüntüleme
