Ct scan showed global atrophic changes with increased extra axial fluid for a 5year old boy what does this mean?

Question?: Extra axial fluid is essentially CSF (cerebral spinal fluid) that is acting as a fluid cushion for the brain. Extra fluid is the face of atrophic changes makes sense - it needs to fill in more space to compensate. Discussing specifics of your child's case really needs to be done face to face with a pediatric neurologist who knows your child's symptoms and test results.

CT scan: The CT is describing loss of brain (atrophy) with increase in fluid (increased extra axial fluid) around the brain - this has occurred due to the lack of full brain development. A consultation with a pediatric neurologist would be helpful to correlate the CT findings with the slinicial findings

Brain injury: The presence of atrophic changes suggested your child has experienced a brain damaging event at some time. To say more requires more information from you. If your child has intellectual or motor deficits you should speak to your pediatrician or pediatric neurologist about what this means in the context of complete history.
