    How reliable is this source?

    I can think of the few of many problems with it:
    Correct me if I'm wrong.
    1. The eggs need to be first go through your stomach acid which would destroy them.
    2. The eggs need to enter through your villi, where the eggs are too small to go through.
    3. The pictures shows worms growing in the thousands. So basically each of the worms have to get past the problems in order to get there.

    1. Wrong. Stomach acid does not kill everything. It is very well possible that the eggs survive.

    2. Wrong. To small to pass through? Strange. Eggs won't pass, small worms however could if they hatch there.

    3. Wrong. Only one cycle of worms needs to pass (or just 1 worm). Then a worm can mature, lay eggs in your brain (or anywhere), die and the next generation of eggs hatches in your brain (or somewhere else).


    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    Not very reliable at all. I've actually came across this urban legend, and the story as detailed in the Mandarin article is entirely fictional. This incident has been documented and published in at least one journal.

    The myth of eating raw fish can get you worms in your brain.

    right?

    right?
    Well, technically those are larvae and not "worms", although colloquially I suppose some do not see the distinction. You may want to read up on Myiasis and how it takes hold.

    Myiasis - Wikipedia, the free encyclopedia

    Based on what little information I've dug up, there hasn't been a documented case of cerebral myiasis due to ingestion of eggs, although there have been some documented cases where larva penetrating through the scalp that has resulted in the condition. As for whether it is possible for the eggs/larvae to "swim" their way from intestinal tracts to the brain, and not simply reside in the digestive system, I'm not sure.

    The life of a roundworm

    The life cycle of roundworms varies between species.

    If you have worms in your gut, the female worm lays many tiny eggs. You pass these out with the stools (motions or faeces). Soil and water supplies may become contaminated with eggs in areas of poor sanitation. Many roundworms have a complicated life cycle that includes both main hosts (large mammals such as humans or pigs) and intermediate hosts (small animals such as snails). Therefore, some roundworm infections occur as a result of eating uncooked contaminated food.

    The eggs may survive for years in moist soil. In the soil the eggs develop into larvae (tiny young worms). Larvae can get into the human gut if you eat them with contaminated food. They are tiny and pass into the bloodstream and are carried to other parts of the body - such as the lungs.


    Larvae develop further and then often travel back to the gut, where the larvae then grow into adult worms. An adult worm can lay many eggs, which are passed out with the stools.

    So these worms can pass and enter the brain as well..

    Those pictures are real. The story is not.
    That particular man had a cancer in his skull, and flies are attracted to gasses emitted from necrotic tissue.
    Oddly enough, maggot infestations like that usually keep the person from developing deadly bacterial infections or gangrene.

    Actual worms do however get into the body all of the time. Sometimes through the digestive tract, or through insect bites, and often directly through the skin.
    Worms that enter the bloodstream usually leave it to live within a protected cyst in skeletal muscle, or sometimes cardiac muscle. Small worms and nematodes live in or just beneath the skin. After maturing they usually leave the body to participate in another part of their life cycle.
    Loa loa are famous for congregating within the eyeball. The pork tapeworm can form cysts in the brain.

    It appears I was mistaken about there not having been a documented case.

    In spite of what Snopes says I think the pictures are faked.
    However they refer to this article.
    Cerebral myiasis associated with angiosarcoma o... [Neurosurgery. 2007] - PubMed - NCBI
    which makes me think they might be real.

    Pretty disgusting either way though, eh?

    There's a video documenting the case in post #3, referencing an assistant Professor of Neurosurgery by the name of Samuel H. Cheshier who is also named in both the article and video.

    1:03 minutes of fascination and horror at the same time.
    I find it simply incredible that a person would not have had it treated before it got that far.
