Case of the Week 441
This week's case was generously donated by Dr. Nipunie Rajapakse. The following object was passed in the stool of a teenage boy with recurrent fevers and constipation. His only travel outside of North America was Portugal and Hawaii. Treatment with an antihelminth was ineffective at alleviating his symptoms and follow-up stool exams were negative.

The object superficial appearance mimics that of a Tenia so., However, there is no visible internal organs or external genitalia.
ReplyDeleteMy guess is that the object is just partially digested food.

Onion skin!

ReplyDeleteIt looks an awful lot like a Tapeworm, more like D. latum to me. However, usually tapeworms have a more opaque appearance, more whitish.
ReplyDeleteThe first thing I would do with this specimen is poke it under a stereoscope. If it falls apart easily it is probably is some sort of vegetable matter/stool artifact (onion skin as others have said?). If it is tough and springy, I would then look for expelled eggs to aid in identification.

Not a parasite. Looks like vegetable matter (specifically, onion) to me.
ReplyDeleteI am not a professional MD, but it looks like it has legs on its underside and it looks also like it has an opening at the shorter left part of it in the pic. I am going to take a shot at saying that this is a tapeworm type of parasite and not just debris as said in an earlier reply. I hope you let us know what it is if you find out!
ReplyDeleteIt is not a parasite. It seems to be small intestine of an animal, probably used for sausage tubing.
