Macrocephaly (or big head) is a very common reason for referral to a pediatric neurosurgeon. Children with macrocephaly have a head circumference (the measurement around the widest part of the head) that is greater than the 98th percentile. Sometimes a large head means that there is a problem in the brain which might require surgery . Primary care physicians may refer to the pediatric neurosurgeon based on your child's increasing head circumference Causes of macrocephaly include Macrocephaly is a condition in which circumference of the human head is abnormally large. It may be pathological or harmless, and can be a familial genetic characteristic.

Macrocephaly occurs in about 15-35% of autistic children and can also be seen in other types of pervasive developmental disorders, and it is clear that this is the most common physical finding in children with autism. The macrocephaly observed in autism becomes manifest around 1-3 years of ag Macrocephaly is a commonly encountered entity in pediatric clinical practice, particularly in infants. It is defined as an occipitofrontal circumference greater than 2 SD, or 0.5 cm above the 97th percentile

Macrocephaly (megacephaly) is a head circumference > 2 standard deviations above the mean for age ( 1, 2 ). (See also Introduction to Congenital Craniofacial and Musculoskeletal Disorders and Overview of Congenital Craniofacial Abnormalities .) There are two types: Disproportionate macrocephaly. Proportionate macrocephaly . Approximately 94% of people with PHTS have head circumferences which measure > 2 standard deviations from the norm for age and gender. On average, head circumference measured + 4.89 standard deviations above the mean for children Megalencephaly: disorder of neuronal and glial proliferation which causes overgrowth of cells and results in severe neurodevelopmental delay. Over 100 syndromes with prenatal or postnatal overgrowth have been described
Macrocephaly is described as a head circumference more than two standard deviations above the mean for gestational age and sex, which falls above the 97th percentile. Although erroneously used interchangeably with macrocephaly, megalencephaly is a distinct term to suggest increased growth of cerebral structure Anatomic megalencephaly resulting in macrocephaly occurs in more than 100 multiple congenital anomaly syndromes. A number of macrocephaly syndromes show accompanying somatic overgrowth, but some show normal somatic growth. This discussion provides a review of several macrocephaly syndromes that might be encountered by the pediatric neurologist
Macrocephaly is associated with many genetic disorders and is a frequent cause of referral to the clinical geneticist. In this review we classify the commonly encountered macrocephaly disorders into useful categories and summarize recent genetic advances. Conditions where macrocephaly is a predomina Megalencephaly is different from macrocephaly (also called megacephaly or megalocephaly), which describes a big head, and which doesn't necessarily indicate abnormality. Large head size is passed down through the generations in some families. × . Definition.

Macrocephaly is a term used to refer to a person who has an abnormally large head. The circumference of the head must be above the 95th percentile or at least 2.5 standard deviations from the mean of normal weight and gender groups in the United States Macrocephaly can result from enlargement of the skull bones or an increase in the volume of the intracranial structures like cerebrospinal fluid (CSF), hydrocephalus, cranial hyperostosis, blood, or enlarged brain (megalencephaly). Macrocephaly may be secondary to raised intracranial pressure or space-occupying lesions
Macrocephaly, also called big head or large head syndrome, is a condition that causes an abnormal increase in the head circumference of the baby. Not all babies have the same head circumference. Therefore, physicians divide head circumferences into different percentiles (1). If the circumference falls within the healthy range for their age and. Increased head size may be from any of the following: Benign familial macrocephaly (family tendency toward large head size) Canavan disease (condition that affects how the body breaks down and uses a protein called aspartic acid); Hydrocephalus (buildup of fluid inside the skull that leads to brain swelling); Bleeding inside the skul recent genetic advances.
