B. usually multiple
C. often associated with cavernous malformation
D. frequently hemorrhage

A

Jawabannya : C

usually is intervening normal brain, unlike with arteriovenous malformations
(AVMs) and capillary telangiectasias. They are usually single, unlike capillarytelangiectasias.
They rarely hemorrhage and are often found along with
cavernous malformations.
