常见肋骨肿瘤和肿瘤样病变的CT诊断

目的:讨论肋骨肿瘤和肿瘤样病变的CT表现以及各自的特点。材料与方法:取经手术和病理证实,或临床动态观察证实的肋骨病变50例。所有病例均行X线、CT检查。2例行MRI检查。结果:32例为良性病变,其中12例为骨岛,9例为骨纤维异常增殖症,7例为软骨类良性肿瘤,4例为骨感染性病变(2例为结核,2例为非特异性感染)。恶性病变18例,其中转移瘤10例,骨髓瘤4例,骨巨细胞瘤4例。结论:常见的肋骨肿瘤和肿瘤样病变一般都具有某些有助于我们诊断的特征性的CT表现。多数情况下,我们都能通过这些CT表现较好的区分常见的肋骨肿瘤和肿瘤样病变。

Computed tomography in the diagnosis of costal tumor and tumorlike lesions

Objective: To discuss the value of CT in the diagnosis of costal tumor or tumorlike lesions. Materials and Methods: All the patients took the examination of CT, two of them took MRI. Results: Thirty-two cases belong to benign lesions, 12 cases of them are bone island, 9 cases are fibrous dysplasia, 7 cases are chondrogenous tumor, 4 cases are infective lesions. Eighteen cases are malignant lesions, 10 cases of them are metastatic tumor, 4 cases are myeloma, 4 cases are giant cell tumor of bone. Conclusion: There are some characteristic CT findings which are helpful to diagnose a certain tumor. We can distinguish benign tumor from malignant tumor of rib in the majority of cases by these characterstics.
