FAQ
Frequently Asked Questions
No. It can be benign (e.g., familial macrocephaly) or a sign of a more serious condition like hydrocephalus or a genetic syndrome. Further investigation is needed for a diagnosis.
Treatment depends on the underlying cause. Benign cases require no treatment. If caused by excess cerebrospinal fluid (hydrocephalus), surgical intervention may be necessary.
Macrocephaly is a descriptive term for a large head. Hydrocephalus is a specific condition involving an accumulation of cerebrospinal fluid in the brain, which is one potential cause of macrocephaly.
It is diagnosed by measuring head circumference and plotting it on standardized growth charts. Imaging studies like ultrasound, CT, or MRI are used to determine the underlying cause.
