摘要目的本研究基于荷兰肥胖流行病学研究的大样本,通过MRI检查确定膝关节内生软骨瘤和非典型软骨类肿瘤/软骨肉瘤1级(ACT/CS1)的患病率。方法年龄为45~65岁的超重或肥胖人群被纳入本项前瞻性研究,在这些参与者中进行了右膝关节的MRI扫描,并通过病灶的位置和影像特征筛查偶然发现的软骨类肿瘤。结果 1 285例受试者中有44例发现了49个软骨类肿瘤(患病率约2.8%,95%CI:2.0%~4.0%)。平均最大肿瘤直径为12 mm(2~31 mm)。有8例病人的肿瘤>20 mm或肿瘤具有侵袭性特征需要排除低级
Abstract Objectives This study was based on a large sample of epidemiological studies of obesity in the Netherlands to determine the prevalence of endochondral and atypical chondrosarcoma / chondrosarcoma grade 1 (ACT / CS1) tumors by MRI. Methods Overweight or obese individuals aged 45-65 years were enrolled in this prospective study. MRI scans of the right knee joint were performed among these participants and occasional cartilaginous tumors were screened for their location and imaging characteristics . Results Forty-nine cartilaginous tumors were found in 44 of 1 285 subjects (prevalence rate of 2.8%, 95% CI: 2.0% to 4.0%). The average maximum tumor diameter was 12 mm (2 to 31 mm). Eight patients had a tumor> 20 mm or the tumor had aggressive features that needed to be excluded
