There are no other symptoms that she has been able to identify. Now she is ordering a CT scan. I would like to put this to rest, on the one hand, but I'm really wary of unneccessary testing. Thanks in advance for any info or similar experiences to share. Head growth usually reflects growth of the underlying brain.
Some normal infants do have disproportionately large heads compared to their lengths and weights.
Indeed, some families simply have healthy members with much larger heads - a benign familial pattern. This could indeed be the case in your family. Rarely, it may reflect the growth of a tumor inside the head. Usually in these latter cases the infant does not thrive. Clearly, a CT scan or a magnetic resonance imaging study will provide much more detailas well as necessary guidance for surgical management.
