U.K. Doctors were shocked to find a "multitude of worms" crawling throughout a 15-year-old girl's appendix (video below).
When the 15-year-old teen visited Royal Cornwall Hospital complaining of nausea and pain on her right side, doctors immediately suspected appendicitis, the Daily Mail reported.
But when ultrasound results, blood tests and urine samples came back clear of infection, doctors were stumped.
Dr. Luke Allen decided to perform a laparoscopy, a surgery that gives medics access to the stomach without having to make a large incision.
Allen found no disease in the uterus, ovaries or small bowel. But when they reached the appendix, they found it “lily white” instead of pink or red.
When they prepared to remove the appendix, a “multitude of worms” came out of the organ.
Medics removed the appendix and used a suction pipe to remove any stray worms. Doctors diagnosed the girl with pinworm, an intestinal infection caused by tiny parasitic worms. The infection is also known as threadworm.
While pinworms are not harmful, they are contagious. The infection occurs when microscopic pinworms eggs are ingested; these can be found on contaminated hands, toilets, kitchen counters and food.
The eggs make their way into the digestive system and hatch in the small intestine, according to BMJ Case Reports. From there, the pinworm larvae reach the large intestine, latching their heads to the inside wall of the bowel.
The 15-year-old girl and her family were treated with medication to get rid of any remaining parasites or eggs. The girl is no longer in pain and made a full recovery.
