This is a very common finding in children with large heads and usually requires no treatment other than careful follow-up. Most children outgrow this extra fluid by early childhood. [chadkids.org]

Depends on the cause Treatment of macrocephaly depends on the cause. Sometimes, no treatment is necessary. If the cause is an abnormality, such as hydrocephalus, treatment, including surgery, may be necessary. NOTE: This is the Consumer Version. [merckmanuals.com]

Prognosis For children with benign familial macrocephaly, the prognosis is excellent. These children usually do not have any complications and have normal intelligence. For other children with macrocephaly, the prognosis is dependent upon the cause. [healthofchildren.com]

Subependymal and subarachnoidal cysts may cause extraodinary displacements and compression of brain structures; nevertheless, the prognosis is rather optimistic, for the brain structure itself is generally not destroyed. [ncbi.nlm.nih.gov]

Prognosis The outcome and prognosis depends on the cause. The prognosis is quite favorable in children with benign familial macrocephaly. [emedicine.medscape.com]

Prognosis: Familial macrocephaly: normal neurological development. Secondary macrocephaly: depends on underlying condition. Unilateral or bilateral megalencephaly: developmental delay and intractable seizures. [fetalmedicine.org]

Etiology The etiology of macrocephaly is diverse. [4] The most common cause is benign familial macrocephaly characterized by enlargement of the subarachnoid spaces and accounts for almost 50% of cases. Other causes are described below. [emedicine.medscape.com]
