Multicameral echinococcus. It is called alveococcus.
Alveococcus is similar to raspberries. This is a cluster of 0.2-0.5mm bubbles. The bubbles contain a gel-like substance. New bubbles gradually form from the outer bubbles. Alveococcus not only presses on the surrounding organs, but also grows in them. Particles of the parasite can come off and get into different organs with blood, and grow there. Doesn't that sound like cancer and metastasis? It is very difficult to distinguish them! The size of the bubbles of the alveococcus is very small. Therefore, for a long time it is impossible to see them on ultrasound, X-ray, CT, NMR. The alveococcus looks like a dense, whitish tumor, riddled with many small cysts in the fibrous stroma. In cut, it looks like unripe cheese of cartilaginous density. Gradually, the central part of the node disintegrates, fills with a pus-like fluid. Outside, the bubbles are actively growing and multiplying. Often the size of the alveococcus is 2-15 sm, but sometimes it reaches the size of an adult's head.
