Osteoid osteoma of the proximal femur: A case report

Abstract

Background : Osteoid osteoma “OO” is a benign bone tumor that has a potential to become malignant. It can affect people of all ages, but is most commonly seen in children and young adults. It commonly involves long bones such as femur and tibia. Patients often present with pain that is worse at night and relieved by non-steroidal anti-inflammatory drugs (NSAIDs). Osteoid osteoma can be diagnosed by imaging studies such as X-rays, a Computed tomography (CT ) scan and MRI as it classically consists of a central vascularized nidus that represents the neoplastic tissue which can be identified on a CT scan. Many different options are being used in the management of osteoid osteoma ranging from analgesics and physiotherapy to surgical intervention if the conservative management failed to relieve the pain. Case report: We are presenting a case of a 12 year old male with Proximal femoral OO who was managed conservatively in the beginning and then treated using X-Ray Guided percutaneous Drilling of the lesion with good postoperative clinical outcome. In this Report we are discussing the surgical steps as well as the prognosis compared to other treatment options. Conclusion: A delay of the diagnosis can occur due to the majority of differential diagnoses and the difficult interpretation of the diagnostic imaging, so a high clinical suspicion and early interventions using more advanced imaging modalities allows earlier diagnosis of ‘’OO’’ and therefore quicker treatment and relief of patient symptoms.
