Question 1

what if a fetus has small head circumference?

Multiple causes: Probably the most common group is due to genetics & these kids grow up fine with normal development & intellectual functioning. The alternatives are many and have variable outcomes: pre-natal injury (toxins, trauma, infection, low oxygen); brain malformations;metabolic disorders ; syndromes
:degenerative disorders. These groups have specific findings on evaluation but may not be detected until older.

Question 4

head circumference - what is too small?

Head circumference: There is a wide range of normal for head circumference, depending on age. Your doctor should be plotting this on a chart at well child visits. Look at both the actual size, and the change in size with time to see if your child's head circumference is normal.

Depends on gender ;: Velocity of growth. Has the head circumference grown normally along a single curve between 5th-95th%ile or increased  too rapidly, e.g., jumping from 25th to 95th %ile (as may be seen in  autism or hydrocephalus), or too slowly,  e.g., dropping from 25th to 5th%ile, (indicating insufficient brain growth)?Girls' range at 9 months is 41.6-46.6 cm; avg. Is 44 cm. Boys, 43-47.4 cm; avg. Is 45.4 cm.

Question 6

i was wondering is a 24in. head circumference large?

Accepted Answer

Not necessarily: For an adult male it is at the larger end of the normal range.For the most part it is only a problem in finding well fitting head ware. It hasn't complicated my life.

Question 8

what does 90% percentile in infant head circumference mean?

Accepted Answer

Relative study: His rating means that 10% of infants at this age have a larger head circumference (size) while 90% are smaller.If the size has increased from 25-50-75-90% over several months it would suggest growth was too rapid.If usually in that range, it just means the kid has a big head.It hasn't bothered me any, except for having trouble finding a helmet/hat that would fit..

Question 9

what is the average head circumference for a 4 year old boy?

Accepted Answer

Head circumference: Head sizes are relatively larger in small children.  In a child without headaches, seizures or major organ deformities, the head circumference is genetically determined and you will not be able to do much about it at four years of age.

Question 10

my baby is 1 month old and her head circumference is 39cm should i be concerned?

Accepted Answer

So far, just enough: To have close monitoring by her pediatrician. That is in the above 90% range but checking for other sign and progress is the correct action to take. I hope everything else seems okay so that this can be explained and/or addressed easily. Don't worry - just have a good full exam done. Best wishes to you and yours!
