My granddaughter was having severe headaches and went to the ER, they did a CT Scan and found a spot on her brain. The ER doctor told her that when she was in the hospital for headaches four years ago is when they found it but she was never told. ER doctor told her that it appear to have not grown as far as the CT Scan shows. What is next?
Spot on brain can be due to anything right from artifact during imaging to structural brain lesion. Considering associated headache i wall suggest MRI brain preferably 3 teslas with contrast. Hope my advice will help you.  Take care. Don't forget to rate me.
