The venous angioarchitecture of sporadic cerebral cavernous malformations: a susceptibility weighted imaging study at 7 T MRI.
To test the hypothesis that sporadic cerebral cavernous malformations (CCMs) are systematically associated with venous malformations (VMs) using susceptibility weighted imaging (SWI) at 7 Tesla (T) field MRI. ⋯ Our data support previous assumptions that sporadic CCMs are systematically associated with local venous abnormalities involving larger outflow vessels. However, the typical appearance of a VM was not confirmed in all cases. The role of the venous environment in the pathomechanism of CCMs remains unclear.
