Abstract
A case is reported of a 14-year old male MZ twin pair, with only one partner affected by situs viscerum inversus, whereby the condition is termed situs viscerum specularis. The high degree of mirror imaging is seen as an abnormal variation of the biological time of the cleavage giving rise to MZ twinning. Electrocardiographic findings are presented and the biological implications of the condition are discussed.
摘要
报道了一例14岁男性单卵双胞胎病例，其中只有一人患有内脏反位，这种情况被称为镜面性内脏反位。高度的镜像现象被视为导致单卵双生的卵裂生物时间的异常变化。文中展示了心电图检查结果，并讨论了该病症的生物学意义。
