Primary Intraosseous Hydatid Cyst: A Case Report

Introduction: Hydatid cyst is primarily localized in the liver. Primary involvement of long bones is rare. Case Presentation: We report a case of primary hydatidosis of the thigh, collected in the Department of Traumatology and Orthopedic Surgery at Ibn Sina University Hospital in Rabat. The patient was a 22-year-old woman. The clinical symptoms were nonspecific. Standard radiography and bone CT scans were suggestive. Chest radiography and abdominal ultrasound were normal. The hydatid serology was positive. She underwent surgical excision and was treated with Albendazole for six months. Histology confirmed the diagnosis. The outcome was favorable, with a median follow-up of two years. Conclusion: Through this case, a review of the literature helps to highlight the epidemiological, clinical, and paraclinical features, as well as the therapeutic modalities for primary bone hydatidosis.
