Description : Cerebral cavernous angiomas are relatively rare vascular malformations that may involve
any part of the central nervous system. Cerebral cavernous angiomas are to be distinguished
from cerebral arteriovenous malformations (106070, 108010). CCMs are venous and not
demonstrable by arteriography; hence they are referred to as angiographically silent.
Capillary hemangiomas (602089) are classified as distinct from vascular malformations
in that hemangiomas are benign, highly proliferative lesions involving aberrant localized
growth of capillary endothelium. Hemangiomas develop shortly after birth. In contrast,
vascular malformations are present from birth, tend to grow with the individual, do
not regress, and show normal rates of endothelial cell turnover (Mulliken and Young,
1988). - Genetic Heterogeneity of CCM CCM2 (603284) is caused by mutation in the CCM2/malcavernin
gene (607929), and CCM3 (603285) is caused by mutation in the PDCD10 gene (609118).
Evidence suggests that a 2-hit mechanism involving biallelic germline and somatic
mutations is responsible for CCM1 pathogenesis, see;
Inheritance : Autosomal dominant;
Molecular basis : Caused by mutation in the Krev interaction trapped 1 gene (KRIT1 604214.0001).;
