Get StartedTests and diagnosis
By Mayo Clinic staffIn babies and young children, hydrocephalus is likely to be diagnosed:
- During gestation as part of a routine prenatal ultrasound
- During infancy or early childhood, when the head is regularly measured as part of growth monitoring
If your baby's head is visibly enlarged or its growth over time is more rapid than that of other infants, your doctor may recommend an ultrasound of the head. If the results of the ultrasound are abnormal, your infant will need further evaluation.
In older children and adults, a doctor may diagnose hydrocephalus after the child or adult develops signs or symptoms of the condition. To help make the diagnosis, your doctor is likely to perform:
- A careful medical history
- A physical and neurological examination
- Computerized tomography (CT) or magnetic resonance imaging (MRI)
If detailed pictures of the brain from imaging tests reveal hydrocephalus or other abnormalities, referral to a brain surgeon for further evaluation and treatment is likely.
