摘要
目的:评价CT在骨盆部软骨肉瘤中的诊断价值。材料与方法:分析总结经手术及病理证实的20例骨盆部软骨肉瘤的平片及CT表现(包括7例复发)。结果:CT能显示所有病例中的软组织包块及肿块内的不同密度,而平片只能在14例中显示有肿块影。CT能显示全部病例的肿瘤内有不同形态的钙化,而平片只显示15例有钙化。CT能清楚显示肿瘤的范围,而平片显示不清楚。CT还能对7例术后复发做出可靠诊断。结论:在骨盆部软骨肉瘤中,CT对肿瘤的定位、瘤内密度的显示、病灶范围及毗邻关系的显示等方面均优于传统X线平片,而且CT对复发的判断很有价值。
Objective: To evaluate CT scan in the diagnosing of chondrosarcoma in pelvis.Materials and Methods:The plain film and CT features of pelvic chondrosarcoma in 20 surgically and pathologically proved cases, including 7 recurrent cases, were reviewed.Results:Soft tissue mass and intra tumorous calcifications were demonstrated on CT in all cases, while demonstrated on plain film only in 14 and 15 cases, respectively. Besides, the extent and outline of the tumor were well visualized on CT, while blurred on plain film. In 7 recurrent cases, CT provided reliable information of recurrence.Conclusion: For the diagnosing of pelvic chodrosarcoma, CT is superior to plain film in displaying tumor extent, location, adjacent structures and intra tumorous density, and is very helpful in judging recurrence.
