Presentation Patterns, Diagnostic Modalities, Management Strategies, and Clinical Outcomes in Patients with Hydatid Disease of the Pelvic Bone: A Comparative Review of 31 Cases

Hydatid disease is a parasitic zoonosis commonly caused by Echinococcus granulosus. It characteristically involves the liver and the lungs but rare occurrences in other organs have also been reported. Bone involvement is distinctly uncommon, which is predominantly a silent and slowly progressive disease with a long latent period. We conducted a systematic literature search of MEDLINE, Cochrane, Embase, and Scopus databases. After a comprehensive review of the search results, a total of 31 cases of hydatid disease of the pelvic bone fulfilled the inclusion criteria. The data on patient demographics, epidemiology, lesion site, management, clinical outcomes, and follow-up were collected and analyzed. This review illustrates that hydatid disease should be considered among the differential diagnoses of unusual cystic lesions of the pelvic bone. Prompt diagnosis and appropriate management are of paramount importance to prevent bone destruction and serious complications in these patients. Long-term follow-up should be performed for potential recurrence.
