Abstract
Thirty-two consecutive cranial computed tomographic (CT) scans in normal infants ranging from 1 day-3 yr of age were evaluated for asymmetry of the temporal lobes as evidence by differences in the size of the sylvian fissures. The left sylvian fissure was larger than the right in 23 of the 32 cases, which was statistically significant (P < 0.0001). In 5 other cases, the 2 sides were equal; and in the 4 remaining cases, the right side was larger than the left. The results show that asymmetry of the temporal lobes can be demonstrated in vivo even at birth and this asymmetry is a normal developmental difference between the 2 hemispheres and not secondary to an acquired abnormality.
