Woman has developed an imaginary, but useful, third arm

After having a stroke, a 64-year-old woman reports that she now has a "pale, milky-white and translucent third arm" that she can use to scratch itchy parts of her body. She also says the limb can't penetrate solid objects.

It is "the first case known to doctors of a person being able to feel, see and deliberately move a limb that doesn't exist." The woman underwent an MRI and when doctors asker her to move her imaginary third limb, her brain responded as if she really had the arm. Her visual cortex activity also indicated that she saw the arm. (Via Arbroath)


  1. Yes… the first diclonius in captivity… i advise the healthcare professionals to be cautious

  2. I’ve heard of avid furries developing phantom tails before… first time I’ve heard of third arms though.

  3. I think the fact that she can satisfy real itches with it is even more freaky than it being imaginary.

  4. For Ceronomus: YOu may enjoy reading “The Man Who Mistook His Wife for a Hat…and Other Clinical Tales by Oliver Sacks (I think). Dr. Sacks has a whole collection of interesting accounts of patients with some really abnormal psychology.

  5. That’s bizarre. Is this the first non-amputation case of someone developing a phantom limb?

  6. Someone needs to hook her up with a prosthetic third limb connected to her neural circuitry. She might get some good use out of it!

  7. When I turned 14 and realized I was far too ugly for any girl to ever want me, I grew an imaginary vagina on my right hand. Works almost as good as the real thing, and I never have to buy diamonds for it.

  8. @29; poop! have to pay to read. Oh well. Anyways, it would have been VERY interesting if she had simultaneous mental control over three limbs.
