Pelvic Hydatid Disease: A Case Report and Review of Literature.

Introduction: Cystic echinococcosis of the bone is rare and difficult to treat due to frequent recurrences, especially in certain locations such as ilium and hip, where radical surgery is difficult to achieve.

Case Report: We present a case of a 35-year-old female of the Indian subcontinent who had complaints of pain in left hip and limp since 1 year. The first clinical and radiological diagnosis was tuberculosis of the hip. However, higher imaging modalities revealed the diagnosis of hydatid disease of hip. The patient underwent surgical debridement and anti-helminthic chemotherapy. At 3-year follow-up, the patient was disease- free.

Conclusion: Hydatid disease of the hip and pelvis, although rare must be kept in the differential diagnosis of pathologies of hip-like tuberculosis. Debridement and excision of hip joint give good functional outcome, while also minimizing morbidities that are usually associated the use of custom-made prosthesis or complex arthroplasty.
