<unk> , also known as cerebral<unk>  malformation (CCM) or cavernoma, is a rare disease that involves the capillaries of the central nervous system. CCMs have dilated endothelial-lined sinusoidal capillaries which lack intervening neural tissue. This is the only characteristic that can distinguish these lesions from capillary telangiectasia.
CCMs can be classified as sporadic or familial, which has an autosomal dominant form of inheritance. The majority of CCMs are recent and remote hemorrhages. These lesions range in size from millimeters to almost less than 3 centimeters in diameter.
