Humans may be considered as the most intelligent animal on the earth but even then there are scores of weird incidents that are beyond our understanding. Though scientists and doctors often end up giving them scientific or medical term, for people like us it is just bizarre.
Before the year ends, we just want to take you through some of the strange medical cases that left the doctors baffled in 2017:
Dead foetus inside a woman for 15 years
A 52-year-old woman in India discovered more than she anticipated after she visited a doctor complaining of abdominal pain. She found out that she had been carrying a dead foetus for 15 years that she had aborted back then.
The doctors at that time assured her that the baby was aborted. Since no sonography was done, neither she nor the doctors knew that the baby was still there.
A baby with mermaid-like features was born in India but couldn't survive more than four hours. The sex of the baby remained unclear due to its fused legs and underdeveloped pelvis.
The baby actually suffered from mermaid syndrome or Sirenomelia which is thought to affect one in every 60,000 to 100,000 births and this was India's second.
3-year-old kid at risk of dying every time she sleeps
A 3-year-old kid was reported to be suffering from a rare and incurable disorder that can kill her every time she falls asleep.
The kid, Paula Teixeira is from Zamora, Spain suffers from the rare disorder known as Ondine Syndrome. There are about 1,000 to 1,200 people affected with this syndrome worldwide.
A person suffering from this condition stops breathing the moment they fall asleep, putting him/her at risk of death.
A 21-year-old woman from Italy was hospitalised later this year with a rare condition of "sweating blood" from her hands and face.
The woman had no visible lesions or abrasions in the area. The woman has reportedly been dealing with this rare condition for three years. She bleeds spontaneously when she is asleep or when she is physically active.
The rare case was published in the Canadian Medical Association Journal.
Conceiving a baby while being pregnant is one of the weirdest things that you may have ever heard, but it's true. A pregnant US woman named Jessica Allen was being a surrogate mother for a Chinese couple when she conceived a child of her own.
The babies were initially considered to be identical twins, but in reality, it was caused by a rare condition – superfetation, where a second conception takes place despite the woman being pregnant.
A man was accused of raping his ex 'in his sleep' who claimed to be unaware of anything like that only to be discovered that he's suffering from sexsomnia.
Dr Guy Leschziner who saw the man's case said: "His brainwaves in his sleep study show something very unusual."
Dr Leschziner mentioned: "He appears to be awake and deeply asleep at the same time. During brief periods we can see the large slow brainwaves of deep sleep, with superimposed fast rhythms, suggesting simultaneously that he is awake."
Brain leaking out
This is one of the scariest case on the list and possibly the most tragic one. A 40-year-old woman's brain dropped out of her skull due to a very rare condition known as Ehlers Danlos Syndrome, FoxNews reported. The condition causes her body's connective tissues to collapse, which means her joints frequently fall apart and it made her brain slip 7 mm out of place.
