Infected fallopian tube. Coloured frontal hysterosalpingogram X-ray of the pelvis of a woman with an infected fallopian tube. At centre left is the uterus, with the two fallopian tubes on either side at its top. The left fallopian tube (right) is filled with a large amount of pus (orange) due to a bacterial infection, a condition known as salpingitis. The infection may have spread from the vagina or uterus and may spread further to the peritoneum, the membrane lining the abdominal cavity. Severe cases of salpingitis can cause scar tissue that blocks the fallopian tube, leading to infertility. Treatment is with antibiotics. A hysterosalpingogram is taken after the introduction of a radio opaque material to the uterus via a catheter (bottom centre) in the vagina.
