There may also be a smaller (microcephaly) or larger (macrocephaly) head circumference than average, which can indicate certain diseases or syndromes. #### Evidence Base The definitions of the concepts were (partly) based on the guidelines Fetal Growth Retardation of the NVOG and PTEN Hamartoma Tumor Syndrome by the VKGN. ### Patient Population The HeadCircumference information model is meant for all patients, including unborn children."> <extension url="http://hl7.org/fhir/StructureDefinition/translation"> <extension url="lang"> <valueCode value="nl-NL" /> </extension> <extension url="content"> <valueMarkdown value="De schedelomvang (ook wel hoofdomtrek) is de grootte van het hoofd rondom gemeten. #### Purpose De schedelomvang kan inzicht geven in de groei van een (ongeboren) kind.
