Abstract
Macrocephaly is commonly encountered in the primary care provider’s office. It is defined as an occipitofrontal circumference that is greater than 2 standard deviations above the mean for the child’s given age. Macrocephaly is a nonspecific clinical finding that may be benign or require further evaluation. An algorithmic approach is useful for aiding in the clinical decision-making process to determine if further evaluation with neuroimaging is warranted. Abnormal findings may signify a harmful underlying cause, requiring referral to a genetic specialist or neurosurgeon.
