原发性滑膜骨软骨瘤病的影像诊断

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。

Imaging Dignosis of Primary Synovial Osteochondromatosis

Objective To analyze the X-ray,CT and MRI appearances of primary synovial osteochondromatosis.Methods CT scanning was performed in 22 cases,of which 16 cases underwent X-ray examination and 2 cases underwent MRI scan.Results Of 22 cases of synovial osteochondromatosis,13 cases were male and 9 cases were female.The monoarticular involvment was found in 20 cases,and double-articular involvment in 2 cases.Variable size and number of the cartilaginous nodules with calcification and ossification within and surround the joints were showed in 20 cases.The soft mass with calcification were showed in 2 cases.Bone destruction were found in 2 cases,which were induced by compression of the cartilaginous nodules,this was confirmed by operations.Conclusion The cartilaginous nodules with calcification or ossification can be shown by X-ray and CT san.The cartilaginous nodules without calcification or ossification can be shown by MR san.
