BACKGROUND AND PURPOSE: The hippocampus plays a role in the verbal and spatial memory processing, learning, and emotions. The purpose of this study was to determine clinical, etiological, and radiological features of isolated @entity4798 . METHODS: We reviewed, 6800 @entity1 with first-ever @entity64 included in our @entity64 Registry between 2004 and 2014. Among them we studied 19 @entity1 with an acute isolated hippocampal @entity1188 confirmed by MRI. RESULTS: Among 6800 @entity1 , 19 @entity1 (0.03%) showed @entity75 in the hippocampal artery territory, allowing us to delineate 5 variant distributions; (1) anterior @entity4798 (4 @entity1 [21%]) were present with altered consciousness, transient @entity1833 , and @entity10931 with @entity2414 . (2) Posterior @entity4798 (3 @entity1 [16%]) developed @entity1296 and dullness at @entity64 onset, @entity911 , @entity2414 . (3) Unilateral complete @entity4798 were present (4 @entity1 [21%]) with @entity911 , object specific @entity1833 , intense mood states changes as well as impulsivity or @entity308 . @entity2414 were found in all @entity1 . (4) Bilateral @entity4798 (3 @entity1 [16%]) had @entity73 and @entity2414 in all @entity1 . All @entity1 had difficulties retrieving specific autobiographical events and retrieving recent memory, and @entity227 . Hippocampal @entity303 was observed in 2 @entity1 with severe immediate, delayed @entity227 , @entity51 in responding to feedback and error correction with dull and aimless appearance lasting several months. (5) Small circumscribed (punctiform) @entity4798 (5 @entity1 [26%]) showed @entity1296 or dullness sensation and difficulties finding words or objects that they use everyday. Cardioembolism (10; 53%) and @entity455 (6; 32%) were the main @entity64 mechanisms. CONCLUSIONS: We described topographic patterns of hippocampal @entity1188 with distinct manifestations and etiologies. We thought that different patterns of @entity4798 are the result of variation in hippocampal arterial supply or reflect a source of @entity887 .
