A 26 yr old lady, secondary infertility of 5 years duration. Hyrtero-salpigo gram done. The right tube is seen running upwards along transverse processed of L1 to L5 vertebra.

Left tube is normal. What may be the cause? In another case of pain abdomen, when I opened up the abdomen, a right fallopian tube was found adherent to an appendix with a thick band.
