I was diagnosed with an arachnoid cyst via CT scan in 1999 but the report does not show the size of the cyst. In 2012 the cyst was measured at 3.1 x 1.6 cm on my right temporal lobe. I have been having issues and I requested a new MRI and the cyst was measured in millimeters instead of centimeters and the size was 22 x 20 x 30 mm. I am racking the internet trying find out how to compare the sizes between the two with no luck. I have tried the standard formula but that comes to 13,200 mm and I know that is not right. I am simply trying to figure out if the cyst has grown since 2012 as I wait on a reluctant GP to refer me to a neurosurgeon.

I was hit by a truck when I was 4 years old which left me in a coma with five skull fractures. I have always been socially different and very irritable although I long for social interaction. This could be my holy grail because no amount of medication has ever worked. If this thing is getting bigger then I know that it is the problem because you can't have the desire to be a good person that I have along with being physically normal yet being so socially abrasive that the world hates your guts without the cause being organic. Any help would be greatly appreciated.
