Fluid-fluid levels have commonly been reported to occur in aneurysmal bone cysts but have also been seen in telangiectatic osteosarcoma, chondroblastoma, and giant cell tumor of bone. The authors reviewed their experience with nine bone and three soft-tissue tumors that showed fluid-fluid levels on computed tomographic or magnetic resonance images. The bone tumors included fibrous dysplasia, simple bone cyst, recurrent malignant fibrous histiocytoma of bone, two classical osteosarcomas, and four aneurysmal bone cysts. The soft-tissue tumors included soft-tissue hemangioma and two synovial sarcomas. Except for aneurysmal bone cysts, these types of tumors have not been reported to be associated with fluid-fluid levels. Radiologic-pathologic correlation was available in seven patients; in all seven, the fluid-fluid levels indicated prior hemorrhage. The authors conclude that the presence of fluid-fluid levels in bone or soft-tissue tumors cannot be considered diagnostic of any particular tumor.
文献报道液-液平面常见于动脉瘤样骨囊肿，但在骨毛细血管扩张性骨肉瘤、软骨母细胞瘤和骨巨细胞瘤中也可见到。作者回顾了他们对9例骨肿瘤和3例软组织肿瘤的诊治经验，这些肿瘤在计算机断层扫描或磁共振图像上显示有液-液平面。骨肿瘤包括骨纤维异常增殖症、单纯性骨囊肿、复发性骨恶性纤维组织细胞瘤、2例经典型骨肉瘤和4例动脉瘤样骨囊肿。软组织肿瘤包括软组织血管瘤和2例滑膜肉瘤。除动脉瘤样骨囊肿外，尚未见其他类型肿瘤与液-液平面相关的报道。7例患者有影像学-病理对照；在所有7例中，液-液平面提示既往有出血。作者得出结论，骨或软组织肿瘤中液-液平面的存在不能被视为任何特定肿瘤的诊断依据。
