INTRODUCTION
Occurrence of a focal lytic lesion which is "hot" on positron emission tomography (PET) scan is presumed to be neoplastic until proven otherwise. Focal osteonecrosis of vertebral body (VB) without collapse is a rare entity with sparse literature available.
CASE REPORT
A focal osteolytic lesion in a patient with a history of breast carcinoma, in remission, thought to be metastatic lesion on magnetic resonance imaging and PET-computed tomography (CT), with an inconclusive CT-guided biopsy, was found to be osteonecrosis on histopathology of aggregates of tissue obtained from the T9 VB during open surgery.
CONCLUSION
Osteonecrosis without a VB collapse is a rare diagnosis, but should be considered a differential when examining suspected metastatic lesions in VB.
引言
在正电子发射断层扫描（PET）上表现为“热”的局灶性溶骨性病变，在未得到其他证明之前，一般认为是肿瘤性病变。椎体（VB）无塌陷的局灶性骨坏死是一种罕见疾病，相关文献较少。
病例报告
一名缓解期乳腺癌患者出现局灶性溶骨性病变，在磁共振成像和PET计算机断层扫描（CT）上被认为是转移瘤，CT引导下活检结果不明确，在开放手术中从T9椎体获取的组织团块病理检查发现为骨坏死。
结论
无椎体塌陷的骨坏死是一种罕见诊断，但在检查疑似椎体转移瘤时应考虑作为鉴别诊断。
