目的分析原发性滑膜骨软骨瘤病的X线、CT和MRI表现。方法22例原发性滑膜骨软骨瘤病患者均行CT扫描,其中16例拍摄X线平片,2例做MRI检查。结果22例中男13例,女9例。20例为单关节发病,2例为双侧关节同时发病。20例表现为关节内或周围大小不一、数目不等的结节状钙化或骨化影,1例表现为髋关节内分叶状软组织块影伴有钙化,并有髋臼骨质破坏,另1例表现为膝关节内条状软组织密度伴有点状钙化。2例关节骨质破坏,手术证实为软骨结节压迫所致。结论X线平片和CT扫描能够显示钙化或骨化的软骨结节,对未钙化或骨化的软骨结节MRI能够清楚显示。
Objective To analyze the X-ray, CT and MRI findings of primary synovial osteochondromatosis. Methods Twenty-two patients with primary synovial osteochondromatosis underwent CT scan, of which 16 were X-ray films and 2 were MRI. Results 22 cases of male 13 cases, 9 cases of female. 20 cases of single joint disease, 2 cases of bilateral joint disease at the same time. 20 cases showed intra-articular or around the different sizes, ranging from nodular calcification or ossification, 1 case showed intra-articular lobulation of soft tissue mass with calcification, and acetabular bone destruction, Another case showed the soft tissue density of the knee with dotted calcification. 2 cases of joint bone destruction, surgery confirmed as cartilage nodules due to oppression. Conclusion X - ray and CT scan can show calcified or ossified cartilaginous nodules, which can be clearly demonstrated on non - calcified or ossified cartilaginous nodules.
