@entity12513 is an @entity74 with numerous causes. One such entity, noninfectious @entity54692 ( @entity54692 ), is an extremely rare disease with a predilection for leptomeningeal and parenchymal arteries and veins. Isolated involvement of the central nervous system is characteristic of @entity54692 , which has also been referred to as @entity17758 ( @entity17758 ). The results of magnetic resonance (MR) imaging and angiography in seven @entity1 with presumed @entity17758 were retrospectively analyzed and correlated. MR images were positive in every case. Characteristically, lesions were multiple, bilateral, and supratentorial. Both gray- and white-matter @entity1188 were identified in four of seven @entity1 ; @entity1188 were most common in the deep white matter. @entity17758 can also appear as primary @entity548 or simulate @entity11 . All lesions identified on MR images were associated with positive angiographic findings of @entity12513 in the corresponding vascular distribution. However, for 12 of 33 vascular distributions with angiographic evidence of @entity12513 , no lesions were identified on MR images. These correlative observations suggest that some @entity1 with proved @entity17758 may have normal MR imaging results.
