Intraosseous lipomas are rare primary benign bone tumors which present with highly nonspecific radiographic features that may lead to equivocal diagnoses. Advanced imaging studies such as MRI with and without contrast and, in some selected cases, tissue sample analyses are required in the diagnostic pathway. Here we describe the second case in the literature of an intraosseous lipoma of the clavicle and the first with extraosseous extension. Subsequent to histologic confirmation the lesion was monitored with clinical and radiologic evaluation.
骨内脂肪瘤是罕见的原发性良性骨肿瘤，其影像学特征高度非特异性，可能导致诊断不明确。在诊断过程中，需要进行先进的影像学检查，如有无对比剂的磁共振成像（MRI），在某些特定情况下，还需要进行组织样本分析。在此，我们描述锁骨骨内脂肪瘤文献中的第二例病例，也是首例伴有骨外扩展的病例。在组织学确诊后，对该病变进行了临床和影像学评估监测。
