Two common forms of CCMs are familial autosomal-dominant inherited form and sporadic form. Familial CCMs are usually present as multiple lesions while sporadic CCMs are often solitary.3 However, a large number of cases assumed to be isolated cases are actually undetected familial forms.4 The case below …
