Abstract
An infant with hemimegalencephaly was studied with MR at 5 days and again at 10 months of age. The initial scan showed an abnormally large left cerebral hemisphere. At the age of 10 months, the left cerebral hemisphere was smaller than the right--an apparent left-sided micrencephaly caused by normal growth of the right hemisphere and arrested growth of the left. The age of imaging of a patient with hemimegalencephaly can be important if the correct diagnosis is to be made.
摘要
一名患有半侧巨脑症的婴儿在5日龄时接受了磁共振成像（MR）检查，并在10月龄时再次接受检查。初次扫描显示左侧大脑半球异常增大。在10月龄时，左侧大脑半球比右侧小——这是由于右侧半球正常生长而左侧半球生长停滞导致的明显左侧脑发育不全。如果要做出正确诊断，对半侧巨脑症患者进行成像检查的时机可能很重要。
