Fluid-fluid levels have been reported in a variety of primary bone and soft-tissue tumours, most frequently in aneurysmal bone cysts, but have never been reported in a metastatic bone lesion. To emphasize such a possibility the authors present a case in which serial computed tomography demonstrated a pulmonary nodule, paratracheal adenopathy and a fluid-fluid level within a rib lesion. Further investigation confirmed a rib metastasis from primary carcinoma of the bronchus.
液-液平面已在多种原发性骨和软组织肿瘤中被报道，最常见于骨动脉瘤样囊肿，但从未在骨转移瘤中被报道过。为强调这种可能性，作者报告了1例病例，该病例的系列计算机断层扫描显示有一个肺结节、气管旁淋巴结肿大以及肋骨病灶内有一个液-液平面。进一步检查证实为支气管原发性癌的肋骨转移。
