Differential diagnosis

Hi, I have a 14 yrs old son who's been recently diagnosed with a cavernous angioma in his left temporal lobe. I know this is a forum for brain tumors, but I've been trying without any success to post a question on the neurology forum. And my doubt is that in the results of the MRI that was performed, the radiologist says it might be either a cavernous angioma or a ganglioglioma, which I understand is some kind of brain tumor.  The radiologist recomended a CT to determinned the real nature of the lesion.  The neurologist that was consulted thinks it is an angioma.  I'd like to know how can we be sure, because I've read thera have been cases where what was being treated as an angioma later on was found out it was really a ganglioglioma.  I'd like to know if there is anything that my son should avoid if the lesion is in fact a cavernous angioma and how big could be the risk with a lesion that is 6mm in size.

I'd appreciate any information you might give us.

Thank you

Does your son have any symptoms? Typically, angiomas in the brain won't present with symptoms until a person is in their 20s or 30s. A CT scan won't hurt, so I would definitely have this done as it'll give more detailed information about the lesion without requiring an invasive approach.
