This month's case is of a 60 year-old Belgian woman with a long history of travel to sub-Saharan Africa. She presented with persistent upper abdominal discomfort and radiologic imaging revealed a large liver cyst. Below are representative photographs (shown at 200X to 400X original magnification) and a video clip of the unstained aspirated material. Identification?
See the fascinating motility of one of these objects:

Echinococcus granulosus, causing a hydatid cyst of the liver. A protoscolex and several hooklets are seen.
Protoscolici ed uncini di Echinococcus granulosus.
What a beautiful case. The photography is superb. Typical hydatid cyst containing protoscoleces and booklets.

What everyone else said, but the video is simply...astonishing.
Great pictures of the hydatid cyst of Echinococcus granulosus! Protoscolex, free hooklets in "hydatid sand"..., by the way, are the rounded structures of photos 4 and 5 calcareous corpuscles?
Dr. Pritt what great news the collaboration of the prestigious ITM...
I concur. What more can I say that hasn't already been stated? Echinococcus granulosus infection, resulting in hydatid cyst of the liver. The protoscolex and hooklets are characteristic of E. granulosus and are presented in such beautiful detail here that I can't help but keep coming back to view the photos and video. What a treat! I learn so much each time I view these case studies, and now with the addition of presentations from the Institute of Tropical Medicine, I can scarcely wait to see what I will learn next week! Thank you for an outstanding blog, Bobbi!
Echinicoccus granulosus with its typical hooklets. I have seen E.granulosus only two times until now, in a laboratory of a tertiary care hospital in Athens, Greece.Thank you for the educational cases.
Many thanks for the very nice comments everybody!
The rounded structures are indeed calcareous corpuscles. No comments on the first photo? It's rather typical too, but rarely seen!
Hello there! This article could not be written any better!
Going through this post reminds me of my previous
roommate! He continually kept talking about this.
I most certainly will forward this article to him. Pretty sure he will have a very good read.
I appreciate you for sharing!
Yes, Idzi. Many thanks for pointing that out to us. As stated in our book, the outer cyst epidermis is multi layered and anucleated.The inner layer is the germinal epithelium.

Very nice pictures of Echinococcus granulosus. Earlier this year we had a patient with a lungcyst. Great to see as a labtechnician.
