OBJECTIVE: Morphological changes of recent small subcortical @entity1188 are not well defined. The purpose of the present study was to describe the MRI characteristics of the evolution for this @entity64 subtype. METHODS: We conducted a retrospective review of @entity1 diagnosed with definite supratentorial recent small subcortical @entity1188 according to the ASCO classification with baseline and follow-up MRI (>= 90   days of @entity64 onset). We investigated the incidence of @entity6675 formation, the @entity1188 volume change, and the positional relationship between @entity4798 and preexisting @entity62 ( @entity62 ) of presumed vascular origin. RESULTS: We identified 62 @entity1 with a median age of 71   years (range: 30-87). Median follow-up period was 26   months (range: 3-99). @entity6675 formation was observed in 38 @entity4798 (61%). Eighteen lesions (29%) were partially adjacent to @entity62 and 7 (11%) were fused into @entity62 . In a multiple logistic regression analysis, age [odds ratio per 5-year increase: 1.34; 95% confidence interval (CI): 1.03-1.80; p   =   0.03] and baseline @entity1188 volume (odds ratio @entity307 -ml increase: 4.7; 95% CI: 1.6-19.7; p   =   0.003) were independent predictors of @entity6675 formation. There was a significant volume reduction between baseline and follow-up @entity4798 (median volume reduction rate: 44%). CONCLUSION: More than one-third of recent small subcortical @entity1188 do not lead to @entity6675 formation and 40% of @entity4798 overlap with @entity62 . Our data indicate the continuity between recent small subcortical @entity1188 and @entity62 .
