Birth measurement of Twin A was at the ~5th percentile for length (39 cm), weight (1410 g), and occipitofrontal
head circumference (27.5 cm), based on the Olsen Premature Girls Chart (which does not account for DS).
Of the 100 children, (68%) 68/100 had normal occipitofrontal
circumference while (28%)28/100had microcephaly and (4%) 4/100 had macrocephaly.
Microcephaly is defined as an occipitofrontal
circumference below the third percentile or greater than 2 SD from the reference range distribution; severe microcephaly is defined clinically as an occipitofrontal
circumference of greater than 3 SD.
For this report, microcephaly was defined as head circumference (HC) (also known as occipitofrontal
circumference) more than 2 SD below the mean for gestational age and sex, according to the Fetal International and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) for fetal and newborn growth (https://intergrowth21.tghn.org/) and the World Health Organization Child Growth Standards for infants (www.who.int/childgrowth/en/).
The co-activation of the occipital lobe is not totally unexpected considering the existence of a fasciculus going between the occipital lobe and the prefrontal cortex: the inferior occipitofrontal
On physical examination at 5 months of age, his length and weight were below the first percentile, and his occipitofrontal
circumference was at the 66th percentile (relative macrocephaly).

[1,2] Birth weight, occipitofrontal
circumference (OFC) and body length of newborn babies are important indicators for evaluating intra-uterine growth. Birth weight may be classified as low (< 2 500 g), normal (2 500-3 999 g), or high ([greater than or equal to] 4 000 g).
(110 It is important to obtain 3 standard views (postero-anterior, lateral and occipitofrontal
or Towne's view) and while any fracture may justify referral for CT, the following are mandatory indications:
Three separate neonatal anthropometric measures were used to define IUGR: a subscapular or triceps skinfold thickness <10th percentile, a ponderal index <25th percentile, and a mid-arm circumference to occipitofrontal
circumference ratio less than one standard deviation.
