Hydatid pregnancy is a term used to describe a rare type of pregnancy that occurs when a fertilized egg implants and grows outside the uterus, typically in the ovary or abdominal cavity. This condition is sometimes referred to as a "tubal pregnancy," "ectopic pregnancy," or "extrauterine pregnancy." Hydatid pregnancy can be dangerous, as the growing embryo can damage surrounding organs and lead to life-threatening bleeding. Treatment typically involves surgery to remove the embryo and minimize harm to the mother. In some cases, medication may be used to dissolve the pregnancy. It is important to seek immediate medical attention if any symptoms of hydatid pregnancy are present, such as abdominal pain, vaginal bleeding, or shoulder pain.
