目的分析骨韧带样纤维瘤的影像学表现,并与病理表现对照。方法选取黑龙江省哈尔滨市第四医院2015年2月—2017年2月收治的骨韧带样纤维瘤患者20例,分析其影像学表现并与病理对照。结果 X线检查溶骨性破坏55.0%为中心性,45.0%为偏心性;CT检查87.5%为溶骨性破坏,软组织肿胀有较清晰的界限;MRI检查显示T1WI病变区域信号强度比对于周边肌肉均为略低信号或等信号;术前误诊率为90.0%,2例与术后病理对照结果一致。结论影像学检查误诊率高,需联合诊断,并结合临床症状与病理表现。
Objective To analyze the radiographic appearance of bone ligamentoid fibroma and compare it with pathological findings. Methods Twenty patients with bone ligamentous fibroma treated at the Fourth Hospital of Harbin City, Heilongjiang Province from February 2015 to February 2017 were selected for analysis of imaging findings and compared with pathology. RESULTS: X-ray examination showed that osteolysis was 55.0% decentralized and 45.0% was eccentric; 87.5% of CT examinations were osteolytic lesions, and soft-tissue swelling had clearer boundaries; MRI examination showed that the signal intensity of T1WI lesion area was higher than that of peripheral muscles. All were slightly lower signal or equal signal; the preoperative misdiagnosis rate was 90.0%, and 2 cases were consistent with postoperative pathological results. Conclusion The rate of misdiagnosis of imaging examinations is high and it is necessary to make a joint diagnosis combined with clinical symptoms and pathological findings.
