Successful treatment of solitary intraosseous haemangioma of the femoral neck.

Intraosseous haemangiomas (IOHs) are benign vascular bone tumours that account for 1% of all primary bone tumours. They are most frequently seen in the vertebrae and skull, and are rarely found in long bones. Herein, we present an uncommon case of a 25-year-old woman with a solitary IOH that occupied the left femoral neck. We describe the clinical, radiological and histological details of the case, as well as the three-year outcome of the surgical treatment, which successfully preserved the femoral head. We also conducted a review of the literature on this uncommon entity.
