Tubal pregnancy. Laparoscopic view of an ectopic pregnancy in a Fallopian tube (blue/purple mass, centre). Ectopic pregnancies result when a fertilised egg implants in tissue other than the uterine wall, and the Fallopian tubes are the most common location. If left undetected, the tube is likely to rupture and cause life-threatening haemorrhaging. The ovary that the tube connects to (white, centre bottom) and the uterus (top left) can also be seen.
