Abstract



Tubal pregnancy is relatively common. A rare variety of it is twinning in which two fetuses occupy the same tube. Another unusual form of twinning is when ectopic tubal pregnancy itself is combined with normal intrauterine pregnancy proper. Quite extraordinary is the present report of two cases occurring in Enugu within a fortnight during which each tube exhibited its own fetus. Microscopy showed that the chorionic villi in each patient manifested either normal appearances or necrotic changes unilaterally, thereby indicating earlier conception in one tube. This appearance supports among other things the hypothesis that tubal conception may self-terminate and leave behind an occlusive lesion.
