Table 3. Basic distinctions between cerebral and dural cavernous malformations (CMs).

	Inheritance	Location	Clinical presentation	No. of lesions	Hemosiderin ring	Recurrence
Cerebral CMs	Autosomal dominant	Most frequently supratentorial	Seizures, focal hemorrhagic neurological impairments	Multiple in familial patients	Present	Common
Dural CMs	Sporadic	Most frequently found in middle cranial fossa and cavernous sinus	Headache, cranial nerve palsies, or mass effect–related neurological abnormalities	Single	Absent	Rare
