An angioma is a benign tumour made up of small blood vessels or lymph vessels.

my daughter, at 13 years old had cavernous angioma and had it removed by surgery. A year later , she has been experiencing headaches and sensations in her head that are scaring her. Is this normal even though the angioma was removed and the scar tissue should have healed by now? Could she just be prone to headaches, or is it some form of a seizure? Thanks, sue

Sounds like a "cherry angioma".

I don't have your answer yet, but I'll try to remember to keep you posted once I get mine. I have the same thing. So far, I found the Angioma Alliance on the internet. There are apparently some studies going on about this in various universities.
