Final answer:
A parovarian cyst is not an abnormal fluid-filled sac of a fallopian tube. Parovarian cysts develop from remnants of embryonic structures called the Wolffian ducts and are found adjacent to the fallopian tubes. They are usually benign and do not typically cause any symptoms or require treatment.
Step-by-step explanation:
No, a parovarian cyst is not an abnormal fluid-filled sac of a fallopian tube. Parovarian cysts, also known as paraovarian cysts or cysts of the broad ligament, are fluid-filled sacs that develop from remnants of embryonic structures called the Wolffian ducts. These cysts are found adjacent to the fallopian tubes and are not part of the fallopian tubes themselves. They are usually benign and do not typically cause any symptoms or require treatment.
