Table.

Baseline characteristics of adults who were alive at the time of their diagnosis of cerebral cavernous malformations

		Incidental presentation (n=61)	Presentation with epileptic seizure or seizures (n=35)	Presentation with ICH or FND (n=38)
Age (years)		45 (34–54)	34 (26–46)	38·5 (32·5–56)
Women		38 (62%)	14 (40%)	27 (71%)
Primary CCM location
	Lobar	42 (69%)	35 (100%)	13 (34%)
	Deep	4 (7%)	0 (0%)	5 (13%)
	Cerebellum	10 (16%)	0 (0%)	8 (21%)
	Brainstem	5* (8%)	0 (0%)	12 (32%)
Multiple CCMs		6 (10%)	11 (31%)	6 (16%)
Associated developmental venous anomaly		11 (18%)	1 (3%)	8 (21%)

Data are median (IQR) or number (%). CCM=cerebral cavernous malformation. ICH=intracranial haemorrhage. FND=focal neurological deficit.

^*Four adults with incidental multiple CCM were allocated a primary brainstem location on the basis of the existence of at least one brainstem CCM.
