We finally got his MRI yesterday after waiting 5 months and there's a mass in the area that joins the 2 hemispheres. Of course, it was all systems go down to the childrens hospital in Manchester because the signs are that it's fast growing, that's why he's gone from 'funny turns' to daily seizures and then to 50 seizures per day. But when we got to Manchester, surprise surprise, they're not going to do his biopsy until 'some time next week' - he'll be slotted into their system.
So we came back home again.
He's well in himself, bouncing around like mad.
I'll let you know more when we know more, re benign/not.
