8. A Nasty Parasite Infection
This story is creepy: about a dude, I saw on neurology when I was an intern. He was from Southeast Asia with altered mental status and abdominal pain, and altered liver function tests.
The pictures of his belly on plain films, CT scan, and MRI showed a mass, but the mass kept looking blurry and like it was changing shape and size.
We sent him for an ultrasound, and the tech nearly had a heart attack because the “tumor” was moving. Turns out the guy had picked up some nasty parasite on his last trip back to visit the family.
We finally saw the 8 cm (3 in) worm moving and swimming around inside its little ball of goo on the recording of the exam. The whole team almost blew chunks that morning.
