摘要:: 目的：探讨成软骨细胞瘤(CB)的影像学表现，观察影像学表现对该病的诊断及鉴别诊断价值。方法：回顾性分析21例经病理证实的CB影像学资料，21例均有X线平片，其中19例为CT扫描，12例为MRI检查。结果：21例影像学资料中，X线表现为骨质破坏者20例，病灶周围硬化边15例，病灶内明显斑点、斑片状及环状、半环状钙化10例。19例CT扫描均显示明确的骨质破坏及硬化边，其中伴有明显的斑点、半环状斑片样钙化16例，骨膜反应5例，周围软组织肿胀11例。12例MRI检查显示边界清楚的长T1、长短混杂T2信号，7例可见明显骨髓水肿，9例可见邻近关节腔积液，3例显示骨膜反应，1例可见软组织肿块，增强3例强化较明显。结论：CB的影像学表现大多具有不同程度的特征性，综合分析X线、CT、MRI对CB的诊断和鉴别诊断具有重要价值。

Abstract:: Objective: To observe the values of the imaging features in the diagnosis and differential diagnosis of chondroblastoma (CB) by surveying the imaging features of CB. Methods: The imaging data of 21 cases of CB proved by pathology were retrospectively analyzed, 21 patients all had x-ray films, among them, 19 cases were scanned by CT and 12 cases were examined by MRI. Results: Among the imaging data of 21 patients, X-ray films manifested that there were 20 cases of destruction of bone, 15 cases of peripheral hardening ring of the focus and ten cases of clear spots, patchy, ring and semiring calcification in the foci. The results of CT of 19 patients demonstrated clear bone destruction and hardening ring, among them, there were 16 cases associated with clear spots, patchy, ring and semiring calcification, five cases with periosteal reaction and 11 cases of peripheral soft tissue swelling. MRI examinations of 12 patients showed clear-cut long T1, long and short mixed T2 signals, seven cases with clear bone marrow edema (BME), nine cases with proximate arthroedema, three cases with periosteal reaction, one case with soft tissue mass and three cases were intensified obviously. Conclusion: The imaging of CB are characterized mostly to different degrees, Comprehensive analysis of X-ray, CT and MRI plays an impotant role in the diagnosis and differential diagnosis of CB.
