The stress fracture of the femoral head rarely occurs; but, it is generally encountered in case of bone insufficiency, and it is exceptional in younger individuals. The main differential diagnosis may include several diseases, namely, slipped upper femoral epiphysis, septic arthritis, osteomyelitis, and Perthes' disease. Bone scintigraphy is very sensitive but lacks specificity. Nowadays, the magnetic resonance imaging (MRI) is the gold standard for an accurate diagnosis.
We present the first description of this pathology in the pediatric population with the particularity of its atypical aspect on MRI through a case of stress fracture of femoral head in 12-year-old female.
Stress fractures may sometimes mimic malignant or infectious lesions and are easily misdiagnosed. MRI is the gold standard which may be the only modality to identify the fracture.
股骨头应力性骨折很少发生；但通常在骨质不足的情况下出现，在较年轻个体中较为罕见。主要鉴别诊断可能包括几种疾病，即股骨头骨骺滑脱、化脓性关节炎、骨髓炎和佩吉特氏病。骨闪烁扫描非常敏感但缺乏特异性。如今，磁共振成像（MRI）是准确诊断的金标准。
我们通过一名12岁女性股骨头应力性骨折病例首次描述了这种在儿科人群中的病理情况，其在MRI上具有非典型表现的特殊性。
应力性骨折有时可能类似恶性或感染性病变，容易被误诊。MRI是金标准，可能是识别骨折的唯一方式。
