Chronic Osteomyelitis Secondary to Hydatid Disease of Bone – A Case Report

INTRODUCTION: Osseous hydatidosis is a rare orthopedic condition. Osseous hydatidosis leading to chronic osteomyelitis is rarer with very few articles published on it. This presents a challenge in diagnosis and treatment. Here, we report a patient with chronic osteomyelitis secondary to Echinococcal infection. CASE REPORT: A 30-year-old lady with fracture left femur operated elsewhere presented with a draining sinus. She underwent a debridement and sequestrectomy. The condition was quiescent until 4 years later when symptoms recurred. She again underwent debridement, sequestrectomy, and saucerisation. The biopsy showed hydatid cyst. CONCLUSION: The diagnosis and treatment are challenging. The chances of recurrence are very high. Multimodality approach is recommended.
