Increased head circumference is when the measured distance around the widest part of the skull is larger than expected for the child's age and background.
Alternative NamesMacrocephaly
ConsiderationsA newborn's head is usually about 2 centimeters larger than the chest size. Between 6 months and 2 years, both measurements are about equal. After 2 years, the chest size becomes larger than the head.
A series of measurements over time that show an increased rate of head growth often can provide more valuable information than a single measurement that is larger than expected.
Increased pressure in the head (increased intracranial pressure) often accompanies increased head circumference. Symptoms associated with this condition include:

Common CausesThe health care provider usually finds macrocephaly during a routine well-baby exam.
What to expect at your health care provider's officeThe health care provider will take a medical history and will perform a physical examination.

Diagnostic tests may vary depending on the suspected cause, but often include:

The symbol for pi (π) has been used in mathematics for centuries to represent the ratio of a circle's circumference to its diameter. The use of the symbol π to represent this ratio was popularized by the Welsh mathematician William Jones in 1706. Jones introduced the symbol in his book "Synopsis Palmariorum Matheseos," where he used π as an abbreviation for "periphery." Over time, the symbol became widely adopted in mathematical literature and is now universally recognized as representing the mathematical constant pi.
