摘要
目的:探讨不典型部位内生软骨瘤临床表现及X线、CT、MRI对其的诊断价值,掌握其影像学特征。方法:回顾性分析18例内生软骨瘤病人的X线、CT、MRI表现及特点,其中女性11例,男性7例,均经过手术病理证实。结果:X线及CT主要表现为患处规则或不规则囊状骨质破坏区,伴或仅表现为沙粒样、爆米花样钙化,无骨皮质破坏,可见典型征象"扇贝征"。MRI表现为分叶状或花环样混杂T 2、混杂T 1信号改变,内见短T 2信号,增强扫描后均显示为不均匀的轻度强化,病变边界清楚。结论:不典型部位的内生软骨瘤有其特征性的临床与影像学表现,结合多种影像学检查方法综合分析,有助于对其准确的定性诊断。
Objective：To discuss the clinical and imaging manih：stations of the untypical cndogcnotts and master the imaging featuress.Methods：Analyzing 18 eases of cnehondroma which were confirmed by sttrgcry and pathology. Results： X-ray and CT showed lesion or i~＇cgttlar cystic lesions of hone dcstrttetion with sand or popcorn like calcification, without cortical hone dcstrttetion,somc showed typical signs of Scallop in Shell syndrmac.MIH showed lohttlatcd or rosette like hybrid T2, hybrid T1 signal change, in short T2ignal and after enhanced scanning showed inhomogcncotts mild enhancement lesion with clear boundary. Conclusion： The untypical cnehondroma has the typical clinical and imaging fcatures, combined with the eomprcnsivc analysis of various examination methods, is hclpfttl for its accttratc qttalitativc diagnosis.
