BACKGROUND: Two types of @entity1188 ( @entity1188 ) are recognized. Internal @entity1188 are usually attributed to either severe @entity850 in large arteries or acute @entity551 events, whereas external @entity1188 are thought to be caused by @entity887 . The aim of this study was to determine the etiologic background and prognosis of external and internal @entity1188 in our @entity1 . METHODS: We reviewed the medical records and diffusion-weighted images of the @entity1 who were admitted to our @entity64 unit with acute @entity63 @entity64 between January 2012 and November 2014. The demographics, clinical features, radiologic investigations, and other etiologic tests of the @entity1 with internal or external @entity1188 were recorded. We determined etiologic @entity64 subtypes according to the automated Causative Classification System. RESULTS: Fifty-three @entity1 with @entity1188 were detected in our registry. Twenty-two (41.5%) of them were @entity1 . The mean age was 69      12.8 (33-98) years. Twenty-one (39.6%) @entity1 had external @entity1188 : 7 (33.3%) of them had large-artery @entity731 (LAA), 8 (38.1%) @entity1 had cardioembolism, 3 (14.3%) @entity1 had @entity64 due to other causes ( @entity1333 ; n  =  3), and etiologic subtype was undetermined in 3  @entity1 (14.3%). Thirty-two (60.4%) @entity1 had internal @entity1188 : 21 (65.6.%) of them had LAA, 5 (15.6%) @entity1 had cardioembolism, 3 (9.4%) @entity1 had @entity64 due to other causes ( @entity439 ; n  =  1, @entity49 due to @entity1860 ; n  =  1, @entity1333 ; n  =  1), and etiologic subtype of 3 (9.4%) @entity1 remained cryptogenic. LAA was significantly associated with internal @entity1188 (P  =  .024). @entity101 was more common in @entity1 with internal @entity1188 (P  =  .035). CONCLUSIONS: In this series, cardioembolism was the most common etiologic subtype in the @entity1 with external @entity1188 , whereas internal @entity1188 were significantly associated with LAA. Uncommon causes should also be investigated in cryptogenic @entity1 .
