【摘要】：目的探讨儿童内生软骨瘤的影像学特征。方法选取2008~2015年26例诊断为内生软骨瘤患儿的影像学资料,影像学分析主要包括:病变的分布、边缘、基质内钙化、骨内膜扇贝样压迹、骨膜反应、磁共振信号特征及骨髓、软组织水肿情况等。结果男性12例,女性14例。年龄2~18岁,平均14.2岁。病变单发18例,多发8例。26例共51个病灶,其中手指骨病灶占41%(21/51),掌骨占25%(13/51),长骨占28%(14/51),肩胛骨、肋骨、足趾骨各1个,各占2%。平片及计算机体层摄影具有特征性诊断价值的征象有弧形、环形的软骨基质钙化约为59%(30/51),膨胀性生长致内缘形成扇贝样压迹约为75%(38/51)。磁共振成像显示,病变呈等-稍长T1长T2信号。本组患者未见骨髓及软组织水肿。结论内生软骨瘤是儿童常见的良性骨肿瘤,具有特征性影像学征象,准确诊断对后续治疗具有非常重要的作用。
[Abstract]:Objective to investigate the imaging features of endochondroma in children. Methods from 2008 to 2015, 26 cases of endochondroma were studied. The imaging data included the distribution of lesions, margin, calcification in matrix, scallop like indentation, periosteal reaction, MRI signal characteristics and bone marrow. Soft tissue edema, etc. Results there were 12 males and 14 females. The average age was 14.2 years. The lesions were solitary in 18 cases and multiple in 8 cases. There were 51 lesions including 41% (21 / 51) of finger bone, 25% (13 / 51) of metacarpal bone, 28% (14 / 51) of long bone, 1 of scapular bone, 1 of rib bone and 2 of toe bone. The signs of characteristic diagnostic value in plain film and computer tomography are arc. The calcification of circular cartilage matrix is about 59% (30 / 51), and the formation of scallop indentation is about 75% (38 / 51) due to swelling growth. Magnetic resonance imaging showed that the lesion showed iso-long T 1 and long T 2 signal intensity. Bone marrow and soft tissue edema were not found in this group. Conclusion endochondroma is a common benign bone tumor in children.
