What's a ocvm & a caa what r the chances of having a mri brain 4-18-13 & a mra brain dec 2012 can this miss anything to cause bleeds to the brain?

Ask your doctor: Occult cerebrovascular malformation and caa is a form of bleeding in the brain which can be hard to detect. If your MRI was done on an open MRI or it was not done with special gradient echo or susceptibility weighted sequences it could miss subtle bleeding. But you should discuss this with your doctor.

3letter words: Ocvm can stand for occult cavernous malformation and caa can stand for cerebral amyloid angiopathy. The former is a structural abnormality - a bunched up leaky not-well formed blood vessel resembling a raspberry that can bleed. The latter is a problem that affects very small brain vessels and can also bleed. The former can be seen on an MRI the latter cannot. There are many other bleeding causes.
