摘要

目的：分析CT/MR成像中液-液平面征象对鉴别原发骨病变良恶性的意义。方法：66例经病理证实的原发骨病变中12例行CT检查，51例行CT与MR检查，3例行MR检查，均可见液-液平面，据液-液平面所占病灶整体比例，将其分为< 1/3、1/3～<2/3、2/3～<100%和100% 4组，由双盲法分析其与病理结果的关系。结果：良性骨病变58例，恶性骨病变8例。液-液平面比例<1/3时，恶性骨病变相对多见（3/8，37.5%），均为骨肉瘤。随着液-液平面比例的增加，良性病变多见，在液-液平面比例≥2/3时，良性病变所占比例为93.6%，多为骨巨细胞瘤合并动脉瘤样骨囊肿与原发动脉瘤样骨囊肿。当液-液平面比例达100%时，均为良性骨病变。结论：液-液平面所占病变比例增加，良性骨病变多见。

Abstract

Objective: To analyze the diagnostic value of fluid-fluid levels in distinguishing benign and malignant bone lesions using CT/MR. Methods: Sixty-six cases of primary bone lesions proven by pathology were reviewed, among which 12 cases were examined by CT, 51 cases were examined by CT and MR, and the other 3 cases were examined by MR. Fluid-fluid levels(FFLs) were identified in all of the cases. The proportion of the lesion occupied by FFLs was estimated as <1/3, 1/3～<2/3, 2/3～<100% and 100%. The proportion was correlated with the pathological diagnosis and confirmed by double blind method. Results: Pathology revealed 58 benign bone lesions and 8 malignant bone lesions. When the degree of FFLs was <1/3, malignant lesions were relatively common(3/8, 37.5%), and all of which were osteosarcoma. With the increasing of FFLs degree, benign lesion became more frequent. When the degree was >2/3, 93.6% of lesions were benign, most of which were giant cell tumors with aneurysmal bone cysts or primary aneurysmal bone cysts. When the lesions were entire FFls, all of them were benign. Conclusions: More proportion of FFLs in primary bone lesion suggests more possibility of benign bone tumor.
