Neurovascular manifestations in XXXX : imaging features and genotype-phenotype correlations.

@entity1 @entity2758 @entity2457 @entity1884 @entity600 @entity74 @entity1462
BACKGROUND AND PURPOSE: @entity1884 is an @entity74 that presents in 10%-20% of @entity1 with various @entity2457 . We aimed to report the radiologic features (phenotype) and the genotype-phenotype correlations of @entity2457 in @entity1884 . MATERIALS AND METHODS: Demographic, clinical, genotypic, and imaging information of 75 @entity1 with @entity1884 with @entity2758 enrolled in the @entity2457 Consortium from 2010 to 2012 were reviewed. RESULTS: Nonshunting, small, superficially located conglomerates of enhancing vessels without enlarged feeding arteries or draining veins called " @entity1462 " were the most commonly observed lesion (46 of 75 @entity1 ; 61%), followed by shunting "nidus-type" brain AVMs that were typically located superficially with a low Spetzler-Martin Grade and a small size (32 of 75 @entity1 ; 43%). Direct high-flow fistulous arteriovenous shunts were present in 9 @entity1 (12%). Other types of @entity1462 ( @entity600 ) were present in 1 @entity1 each. @entity1462 was seen in 33 cases (44%). No statistically significant correlation was observed between @entity1884 gene mutation and lesion type or lesion multiplicity. CONCLUSIONS: Depending on their imaging features, @entity2457 in @entity1884 can be subdivided into brain AVF, nidus-type AVM, and @entity1462 , with the latter being the most common phenotype in @entity1884 . No genotype-phenotype correlation was observed among @entity1 with this condition.
