RESUMO
OBJECTIVE: In this study, we review the reported cases of hydatid disease of the bone in terms of etiology, pathogenesis, and histopathologic, serologic, and radiographic features and management of the disease. STUDY DESIGN: The present case study reports an extremely rare occurrence of intraosseous hydatid cysts in the orofacial region, wherein 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 compare the aspects reported in previous cases of mandibular hydatid cyst with those of the present case. RESULTS: Hydatid cysts were found to be present in almost every bone of the skeleton in patients (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 5 reports on mandibular bone have been published previously, of which 3 were primary. CONCLUSION: Because of the lack of usual presentations and radiographic features, the presence of hydatid cysts in unusual anatomic locations makes differential diagnosis difficult. The potential risk of anaphylactic shock in susceptible individuals, high recurrence rate, and risk of secondary hydatidosis pose diagnostic and surgical challenges.
