A Girl In Japan Has An Ovary With A Mind All It's Own

Submitted by: richanddead 1 week ago Science



About one-fifth of ovarian tumours contain foreign tissue, including hair, teeth, cartilage, fat and muscle. These tumours, which are normally benign, are named teratomas after the Greek word “teras”, meaning monster. A fair description given the grim medical oddity discovered when a sixteen-year-old girl went into surgery to have her appendix removed. 

During the procedure, doctors found a 10-centimetre-wide tumor and so doctors decided to remove the anomaly. To their surprise, when they examined the tumor they found that it had matted hair, a thin plate of skull bone, and  a 3-centimetre-wide brain-like structure. It was so complete it even had a cerebellum, a part of the brain at the back of the skull in vertebrates, which functions to coordinate and regulate muscular activity.. A mass on one side resembled a brain stem and the miniature brain even developed in such a way that electric impulses could transmit between neurons. 


Brain cells are often found in ovarian teratomas, but it is extremely unusual for them to organise themselves into proper brain-like structures. So far medical science has yet to definitively define what causes ovarian teratomas, one competing theory is that they arise when immature egg cells mutate and turn rogue, producing different parts of the anatomy. Interestingly though, this one though seemed to be of sound mind.

My wife has an ovary that just floats around and outputs estrogen.  No twin, no uterus, no cervix...just a floating hormone factory to balance out.  Thank you endometriosis!

But seriously, she is very happy being healthy now, but it took her years to find a doctor that would say "yeah, you aren't having kids because of this disease and you are in serious pain, let's take that shit out".  So many of doctors were "but having children is the best thing in life, you don't really want to be infertile do you?"  FUCK OFF I'M IN PAIN was her response usually.  And yet none recommended a hysterectomy until the last one.  Honestly, she could have died just to preserve someone's personal beliefs.

kalron27 My wife went through the same thing. The thing with her was, her regular gyno was all for the hysterectomy, for the same reason as your wife's, but our insurance company wouldn't play ball. They kept coming up with the same bullshit you are talking about: "you're too young (she was 26 at the time, iirc) to have a hysterectomy, you may want another kid one day (we already had 2, which is plenty), we don't want you to be on hormone therapy for the rest of your life, etc., ad nauseum". Meanwhile, she's in constant pain, and hemorrhaging pretty badly. My employer at the time switched to a different insurance company, and the new company was basically asking, "why has this been going on this long? Perform the surgery already!"

whosaidwhat Yep, I understand completely.  Fortunately for now no hormone therapy since the one ovary was salvageable and our insurance didn't put up a fight at all.  I really think this is a larger problem than we know or even hear about.  Glad your wife is happy and health finally.

kalron27 Yeah, she wasn't so lucky with the hormone issue, though. Both of her ovaries were left, but never really worked correctly, due to her doctor having to "chemically induce" menopause to help control the pain and bleeding while we were fighting the insurance company. Her ovaries kind of "limped along" until the last couple of years, when they stopped working completely. She's only 40. But, she manages with hormone therapy.

Makes me wonder if this might be related to another medical condition. I can't recall the name of the condition, but it happens when two distinct fetuses (feti?) develop, but one "absorbs" the other very early on. This often results in people having body "structures" in odd places. I seem to recall hearing about one such case where a person had almost a full set of teeth, fairly well developed, removed from their brain. Very bizarre.

When I first saw the head line I thought it might be an ectopic pregnancy that died without ever being detected before now however the article is just weird. I am glad she went through surgery ok .

Thankfully, the girl has recovered completely and is doing well post-surgery.
