My daughter is 13 yrs old and has frequent headaches also . She had an MRI of the brain and hers showed she has a pineal cyst. The doctor said they see this alot when kids are going through puberty. This MRI they did to rule out any head trauma as a child because she is ADD-LD. As a child she fell out of a car 3 times. How did your brothers brain tumor get detected? The reason iam asking is that they have put my daughter on concerta for ADD and than nortripaline(Pamelor) for depression and headaches. She is still having the headaches. Please let me know I would appreciate any helpful advice. My e-mail is luvcarosel@aol.com
