A cavernous malformation or also called cavernous angioma or
cavernous hemangioma or cavernoma is a malformation in the
capillaries, and when located in the brain or spine (nervous
system) may bleed and in turn can cause neurological deficits. The
shape of this malformation resembles that of a raspberry/ These
neurological deficits may be headaches, dizziness, double vision,
memory issues etc. This is also dependent on the location of the
malformation as well as the size of the lesion and size of the
bleed. Many people that have a cavernous malformation will never
know they have them because they remain asymptomatic.
There are people that have one cavernous malformation in what is
called the sporadic form of the disease, while others have multiple
cavernous malformations due to a genetic mutation in one of tree
genes (ccm1, ccm2, and ccm3).
