A 18-year-old male presented with low back ache. The patient was investigated and was diagnosed to have painful scoliosis. X-ray and other examinations could not reveal any diagnosis. The patient was referred to undergo bone scan on clinical suspicion of osteoid osteoma and to rule out stress fracture if any. Planar bone scan was performed, which showed a lesion in L3 vertebra and was further evaluated with SPECT (Single photon emission computed tomography) study to characterize the lesion. On SPECT examination, the classical features of osteoid osteoma, the double density sign (11), was noted in the pars interarticularis region. These findings were confirmed by a CT scan, which showed a sclerotic lesion in pars interarticularis of L3 vertebra. The patient was posted for operation and was relieved of symptoms in the postoperative follow-up.
一名18岁男性因下背部疼痛就诊。对该患者进行了检查，诊断为疼痛性脊柱侧凸。X线及其他检查未能明确诊断。临床怀疑为骨样骨瘤，为排除应力性骨折，患者被转诊接受骨扫描。进行了平面骨扫描，结果显示L3椎体有一病变，随后通过单光子发射计算机断层扫描（SPECT）进一步评估该病变以明确其特征。在SPECT检查中，在关节突间区发现了骨样骨瘤的典型特征——双密度征（11）。CT扫描证实了这些发现，显示L3椎体关节突间区有一硬化性病变。该患者接受了手术，术后随访症状缓解。
