摘要
目的:分析成软骨细胞瘤的CT与MR征像,探讨其诊断价值。方法:对11例成软骨细胞瘤的CT与MR资料进行回顾性分析研究,重点分析其骨骼病灶的形态、周围的组织改变情况。结果:成软骨细胞瘤骨内病灶形态呈良性表现,CT呈边界清晰的溶骨性破坏,其内见有钙化;MR呈边界清楚的长T1长短混杂T2信号区。同时在病灶周围有6例出现软组织肿胀或/和邻近关节囊肿胀,7例出现骨膜反应。结论:成软骨细胞瘤不仅具有良性肿瘤的典型病灶形态,而且在软组织肿胀、骨膜反应及累及邻近关节等方面也具有独特的表现,认识这些征像对本病的诊断与鉴别诊断具有重要作用。
Objective： To analyze CT and MR findings of chondroblastoma and to explore the relationship between the lession and the changes around it.Methods：ll cases with chondroblastoma of bone were examined with CT and MR. The periosteal reaction, swelling of soft tissue, and involved joint were paid more attention.Results： The imaging findings of chondroblastoma showed benign features in shape of lesion. Swelling of soft tissue and/or joint were found in 6 eases, and periosteal reactions were found in 7 eases. Conclusion： Not only the benign lesion of bone but also the special feature in soft tissue, joint and periosteal reaction were found in chondroblastoma eases. To recognize these special X-ray findings of chondroblastoma is very important in the diagnosis of chondroblastoma.
