Atypically Located Hydatid Cysts in Human Morphology

Hydatid cysts (HC) caused by Echinococcus granulosus (EG) larvae are commonly observed in the liver and lungs; however, atypical localizations also occur.This study investigates the frequency of atypically located HC and their relationship with surgical history.Cysts can be found in regions such as the diaphragm, mediastinum, and myocardium within the thoracic cavity, and in the spleen, kidneys, brain, and bone tissue outside the thoracic cavity.Patients with a surgical history exhibit an increased risk of complications and longer hospital stays, which affect treatment processes.The findings suggest that atypical cysts may be related to surgical incision lines.As a result, systematic screening and the development of existing surgical techniques are recommended for patients at risk of Echinococcus granulosus infection.This study provides important insights into the diagnosis and treatment of atypical hydatid cysts and lays the groundwork for future research.
