The aim of this paper is to review the imaging findings in hydatid disease focusing on the complications of it; using cases seen in our hospital with hydatidosis complicated.

The hydatidic disease is a zoonosis produced by the larval stage of the tapeworm Echinococcus granulosus. There are other types of hydatid disease caused by E multilocularis, E. vogeli and E. Oligarthrus but these are much less frequent. It is a worldwide disease. It`s considered an endemic disease in regions such as the Mediterranean countries, Africa, South America, Australia and New Zealand. Mainly affects rural areas. Spain is one of the countries where the disease is endemic, although the incidence of hydatid disease has decreased...

In human, hydatid disease involves the liver in approximately 75% of cases, the lung in 15% and other anatomic locations in 10% (1). The right lobe in the most frequently involved part of the liver. Imaging findings in hepatic hydatid disease depend on the stage of the cyst growth: 1. - PLAIN RADIOGRAPHY: Calcification is seen at radiography in 20-30% (Fig. 2a) of hydatid cysts and usually manifests with a curvilinear or ringlike (Fig. 3a) pattern representing calcification of the pericyst (1). During the natural...

Hydatidosis is a dynamic entity with very different images. Imaging findings range from purely cystic lesions to solid-appearing masses (5) and it can affect almost any part of the body. Hydatid disease primarily affects the liver and presents some findings in imaging tests very characteristic and well known. However, there are multiple potential local complications and secondary possible involvement to other organs almost any anatomical location, by hematogenous spread. The combination of serological tests and radiology, especially in patients living in endemic areas, may contribute...
