Primary intraosseous mandibular hydatid cyst: A case report and review of 97 cases of osseous cystic echinococcosis

Published:October 29, 2021DOI:



      : In this study, we aimed to review the reported cases of hydatid disease of the bone in terms of etiology, pathogenesis, and histopathologic, serologic, and radiographic features, and the management of the disease.

      Study Design

      : The present case study reports an extremely rare occurrence of intraosseous hydatid cysts in the orofacial region, wherein the symptoms or signs of systemic hydatid disease were absent. We discuss the challenges encountered during the diagnosis and treatment of osseous hydatidosis, and reviewed articles on osseous hydatidosis, including 97 cases. We also compared the aspects reported in previous cases of mandibular hydatid cyst with that of the present case.


      : Hydatid cysts were found to be present in almost every bone of the skeleton in patients, with mean age of 39.95 ± 19.67 years (range, 3–76 years). A slight male preference (58.8%) was observed. A history of rural lifestyle, animal bites, and trauma in the affected bone was reported. Only five reports on mandibular bone have been published previously, of which three were primary.


      : The presence of hydatid cysts in unusual anatomic locations, mainly due to the lack of usual presentations and radiographic features, makes differential diagnosis difficult. The potential risk of anaphylactic shock in susceptible individuals, high recurrence rate, and the risk of secondary hydatidosis poses diagnostic and surgical challenges.
