Re: Cloacal anaomaly
Just an educated guess, but it sounds like the term means the baby may have an unusual rectum or anus. Some babies are born with no rectal opening and that's called an "imperforate anus". That calls for a surgical repair soon after birth.
Ask you doctor to explain what the ultrasound showed, what it might mean, and if there's another test (or repeat of that type US) that will clear up the confusion. Also, shame on the doctor for failing to make sure you understood all about it right away. That is part of the doctor's job.
