What is the study of choice for an infant who
presents with macrocephaly?
Head ultrasound (US)
What is the study of choice for an infant who
presents with absolute microcephaly?
Brain MRI
Child with enlarged head > 98th percentile, similar to the father, no symptoms and normal cognitive function, head imaging study showed prominent subarachnoid space especially in the frontal region
Benign familial macrocephaly
Anterior displacement of the occiput on one side and the frontal region on the ipsilateral side and the ear is more anterior on the side of occipital flattening (parallelogram)
Positional plagiocephaly
Anterior displacement of the occiput on one side and frontal bossing on the contralateral side and the ear is displaced more posteriorly (trapezoid)
Posterior plagiocephaly (craniosynostosis)
The most common type of craniosynostosis
Long narrow head (scaphocephaly), which is an early closure of the sagittal sutures
A 6-month-old with progressive head enlargement and crossing percentiles from 25th percentile at 2 months to 98th percentile at 6 months well visits.
The head is elongated in the anterior–posterior diameter and shortened in the biparietal diameter. Ridging of the sagittal suture is palpable
Scaphocephaly (craniosynostosis)
What is the next best step in a child with suspected craniosynostosis?
Refer to a pediatric neurosurgeon (imaging
studies are not required to make the diagnosis in typical cases)
