A woman was horrified when it turned out that what she thought was an innocent holiday beast was fly larvae embedded in her head.
The 55-year-old tourist, who has not been named, returned to the UK from a trip to Uganda, Africa, with a swollen bump on her head.
The women went to the doctor nine days later, complaining of swelling and pain and were initially sent home with antibiotics for an infection.
But on a second visit to her doctor, closer inspection found fly eggs in the middle of her piss-filled lump, as documented in the British Medical Journal.
A small opening was found in the middle of the lump, which, according to experts, was a breathing hole for a baby fly or worm.
The BMJ outlines how doctors applied a vaseline in the field before "one larva was extracted manually and sent to the London School of Tropical Medicine for research".
The larva was identified as Lund's fly – a rare species from the African rainforests.
Another ultrasound of the woman found another made in her head, which meant she had to be operated for removal.
Dr. Farah Shahi, a contagious disease specialist at the British Teaching Hospital in York, told LiveScience that a fly or maggot might have laid eggs on a towel that the woman used to wrap her hair and then twist her forehead.
The woman has since recovered and the authors of the report have mentioned only one other case that has been registered in the United Kingdom since 2015.
