E. vogeli is similar to E. multilocularis in that both species produces many small cysts that spread throughout the internal organs of the infected animal.

The ingestion of E. vogeli eggs, and the spreading of the cysts through infected host, will result in polycystic echinococcosis.

For example, cysts located in a patient's lungs will result in shortness of breath, coughing, and/or chest pain.

Eggs that are eaten by the rodent form hydatid cysts in the lungs, liver, and other internal organs.

[4] The diagnosis of polycystic echinococcosis involves isolating the protoscoleces during surgery or after the patient's death in order to identify E. vogeli.

[5] Polycystic echinococcosis (PE) is an extremely lethal helminthic disease in humans, which is caused by the larval form of E. vogeli.

[4] Type II seems to have the highest mortality rate due to the complications involved with hepatic insufficiency.

Due to the similarities between liver cancer and polycystic echinococcosis, PE is hard to diagnose and could deadly when metastasized to other organs.

Polycystic echinococcosis has infected people in Panama, Colombia, Ecuador, Venezuela, Peru, Brazil, and Suriname.
