摘　　要：目的分析对比软骨母细胞瘤的X线、CT及MR影像学特征。方法分析经病理证实且于2周内行X线、CT和MR检查的22例软骨母细胞瘤病人的影像学表现。2例同时行CT平扫和增强扫描,7例同时行MR平扫和增强扫描。结果病灶位于胫骨上端11例,股骨下端4例,髌骨2例,肱骨上端、股骨上端、颞骨和下颌骨各1例。1例恶性者发生于髂骨并同时累及骶骨。X线表现为骨质破坏(21),病灶内斑片状、斑点状和(或)条状致密影(5),病灶周围边界不清的斑片状硬化(10)。CT上,病灶呈类圆形分叶状(14),内为软组织密度(7),伴有斑片状、斑点状和(或)结节状钙化(15),病灶周围出现边界不清的斑片状硬化(15),病变周围软组织肿胀(18)。病灶在T2WI和脂肪预饱和T2WI均呈混杂信号(22),病灶周围髓腔内有边界不清的斑片状长T1长T2信号(20)。结论良性软骨母细胞瘤的影像学表现多具有特征性,X线平片、CT和MRI多数征象相互对应。Objective To analyze X - ray, CT and M RI characteristics of chondroblastoma. Methods Imaging （ CT,X - ray and M RI） signs of chondroblastoma confirmed by pathology in 22 cases were analyzed. 2 cases and 7 cases underwent contrast - enhanced CT and MRI examination respectivety. Results The lesions were located in tibia （ n = 11 ） , femur （ n = 4 ） , patella （ n = 2 ） , humerus （ n = 1 ） , temporal（ n = 1 ） , mandibal（ n = 1 ） , iliac bone with sacrum （ n = 1 ）. X - ray manifestations were bone destruction（21 ） , stripe or spotty calcification （5） and patchy sclerosis around the lesion（10）. On CT, the lesions were lobular- and -oval（14） ,density of soft tissue （7） with stripe or spotty calcification （15）,patchy sclerosis around （15） and soft tissue swelling （18）. Mixed signal intensity on T2WI and FS T2WI, patchy long T1 and long T2 signal intensity around the lesions （20）. Conclusion The imaging features of benign chondroblastoma are of certain characteristic and most signs on X -ray, CT and MR are corresponded with each other.
