Atypical Proximal Femoral Osteoid Osteoma

[摘要] Background: Osteoid-osteoma is the third most common benign bone neoplasm, occurring predominantly in young which can cause debilitating pain. In most cases, the patients presents with pain that is worsened at night and is alleviated with the use of non-steroidal anti-inflammatory drugs. Conventional radiography or computed tomography shows a well-defined lytic area representing the vascular central nidus, surrounded by sclerosis and cortical thickening. For symptomatic patients the treatment is resection and curettage and the results are generally favourable. Case Report: An unusual case of osteoid osteoma is presented which had a diagnosis dilemma and her symptoms were cured incidentally by curettage of the nidus. Conclusion: Osteoid osteoma can present in unusual way and a high index of suspicion is essential for appropriate management.
