Summary
Bone cystic echinococcosis, a rare condition, often recurs, especially in the hip and pelvis. Medical therapy with Mebendazole offers a potential treatment alternative for extensive hydatid disease.
Area of Science:
- Infectious Diseases
- Parasitology
- Orthopedic Surgery
Background:
- Bone cystic echinococcosis is a rare parasitic infection.
- Management is challenging due to high recurrence rates and surgical difficulties in specific locations like the proximal femur and ilium.
Observation:
- A 37-year-old male presented with hip pain and limp, initially misdiagnosed as osteoarthritis.
- Advanced imaging revealed extensive pelvic hydatid disease.
- The patient received anthelminthic chemotherapy.
Findings:
- At 7-year follow-up, lesions remained stable with chemotherapy.
- The patient experienced persistent hip pain and required crutches for ambulation.
Implications:
- Hydatid disease should be considered in hip pathologies differential diagnosis, alongside conditions like septic arthritis or tuberculosis.
- Prolonged anthelmintic therapy can be a viable alternative to high-risk surgery for extensive bone echinococcosis.
- This case highlights the potential of medical management for challenging bone echinococcosis cases.
