Hydatidosis with Atypical Localization: Report of Three Cases and Literature Review

Echinococcosis is a common parasitic disease with a heavy public health burden in many geographic regions and populations, mainly in the Mediterranean basin, Western China, Central Asia and South America. Most often, echinococcosis affects the liver and lungs. Despite being rare, other organ involvement may occur. We report three original cases of atypical localization of hydatid cysts from diagnosis to treatment to underline this disease's challenges. The affected organs are bone, heart, and brain. Thus, in endemic regions, hydatid cysts should be considered as a differential diagnosis of patients with cystic masses, even in unusual sites. These cases highlight the importance for clinicians to remain vigilant for atypical localizations of echinococcosis, emphasizing the need for early recognition and accurate diagnosis, even in uncommon sites.
