Intramuscular Hydatid Cyst: A Literature Review on Clinical Findings, Diagnosis, and Treatment

The aim of this article is to provide a comprehensive approach to hydatid cyst, a zoonotic disease caused by Echinococcus granulosus. The parasite maintains its life cycle primarily in dogs and sheep; human infection occurs through excessive contact with these animals or the consumption of food or water contaminated with their feces. In isolated muscular cyst cases, negative serological test results are possible, requiring careful attention during diagnosis. Cystic lesions in endemic regions and typical imaging features should raise suspicion. Avoiding invasive procedures is vital to prevent the spread of the parasite. The association between classical imaging findings and endemic regions suggests that any cystic lesion may be a potential indicator of this disease. In this article, two sporadic cases of primary hydatid cysts are presented-one located in the sacral paravertebral region and the other in the gluteus maximus muscle.
