It's hard to look away from this ultrasound.
A shocking photo of an ultrasound of a man's stomach shows parasitic roundworms squirming around.
According to the report in The New England Journal of Medicine, the 20-year-old man went to the emergency room after experiencing vomiting, abdominal pain, and diarrhea, Science Alert reported.
Before the bizarre incident happened, the man was allegedly healthy and had no known medical conditions, according to the report. At the hospital, doctors performed an ultrasound on the large vein near the stomach to check his blood vessels' fluid levels.
In the report, the authors shared that doctors found a "tubular … structure that moved with a curling motion" inside his stomach. When doctors asked him for a stool sample, they found parasites. The ultrasound found eggs from the roundworm Ascaris lumbricoides, a type of parasite found in people's stomachs.
The Centers for Disease Control and Prevention reports that a lumbricoides is the most common parasitic worm found in humans. Around 800 million to 1.2 billion people have the parasite in their intestinal tracts.
However, it is scarce in the United States, and the worm is mostly found in tropical and subtropical areas with poor sanitation systems. It has previously been reported that the worm is commonly found in India.
When eating fruits and vegetables grown in contaminated soil, the CDC says a person can become infected when they absorb eggs from the parasite. People can become contaminated with dirt if they do not wash their hands.
The disease can be treated with antiparasitic drugs. In this case, the man was given albendazole and was quickly released from the hospital after one day. Two weeks later, the man went to a doctor's appointment and said he felt okay.
