I was involved in a terrible vehicle accident and another one 7 months after....in my diagnosis from the first accident the ct scan made an incidental note of the cavum velum interpositum and in my second accident the ct scan said in the comparison section referring to the first diagnosis that it was larger......now this along with many other diagnosises have never and were never discussed with me...my doctor said it was too long he didn't have time to go over it with me just read it myself......other medical people said they didn't know they cant discuss it with me...…..what I have read is it is a space in our head in infants and goes away as you grow older,,,, yet I am 42 been healthy as a horse and since these 2 vehicle accidents have had to shut my company down ...on disability....cant barely sweep floor,,, have tons of head issues and 12 other issues never dealt with …….please what does cavum velum interpositum mean to me
