Charcot关节病的影像学表现

目的分析Charcot关节病的X线、CT和MRI的影像学特征。方法搜集经临床或病理证实的Charcot关节病患者9例，分析各个受累关节的影像学表现。结果X线及CT表现：软组织肿胀9例，骨质吸收5例，骨质增生硬化7例，骨膜反应7例，关节内及关节周围骨化或钙化9例，关节脱位或半脱位4例；MRI表现：软组织肿胀、关节囊内水肿2例，骨髓水肿1例，近端骨质损伤1例;钆喷替酸葡甲胺增强扫描，肥厚关节囊及肿胀的软组织呈明显不均匀强化。1例骨显像呈团块状放射性浓聚。结论X线是诊断Charcot关节病的首选方法，CT、MRI及核素检查是X线的重要补充。

Imaging Features of Charcot Neuroarthropathy: 9 Cases Report

ObjectiveTo investigate the imaging findings of Charcot neuroarthropathy. Methods9 cases with Charcot neuroarthropathy determined clinically or pathologically were reviewed. ResultsThe findings of X-ray and CT including: soft tissue swelling in 9 cases, bone absorption in 5, bone proliferation in 7, periosteal reaction in 7, ectopic calcification or ossification in 9, luxation or semiluxation in 4. For MRI: soft tissue swelling, edema of joint capsule in 2, bone marrow dropsy in 1, sclerotin damage in 1. The joint capsule and periarticular soft tissue unevenly enhanced after Gd-DTPA. Nuclear medicine displayed radioactivity aggregation in 1 case. ConclusionX-rays plain film is the first choice for the diagnosis of Charcot neuroarthropathy, while CT, MRI and nuclear medicine may be helpful.
