ObjectiveTo discuss the MRI diagnostic criteria, classification and lesion characteristics of medial discoid meniscus of the knee. MethodsWe retrospectively analyzed the clinical data of all patients who accepted MRI examination of knee from November 2009 to March 2015.Twenty-six of them (28 knees) with medial discoid meniscus were screened out.We measured and analyzed in all cases the ratio of the width of meniscus to that of tibial plateau on coronal slice, and the thickest thickness of the meniscus posterior horn on sagittal slice.All cases were divided into complete and incomplete type according to MRI findings, and then we compared the lesion rate of the two types of medial discoid meniscus. ResultsTwenty-eight cases were divided into complete type (n=16) and incomplete type (n=12);there were 17 cases of medial discoid meniscal tears, with a lesion rate of 60.7%.The ratio of the width of meniscus to that of tibial plateau on coronal slice was 0.29±0.06, and the thickest thickness of the meniscus posterior horn was (5.31±0.92) mm.The lesion rate of complete type was 81.2%, and 33.3% of the incomplete type.The lesion rate of the complete type was higher than that of the incomplete type, and the difference was statistically significant (P < 0.05). ConclusionsThree MRI diagnostic criteria for medial discoid meniscus are 3 or more than 3 consecutive layers discoid meniscus "tie-like" change in sagittal slice, the ratio of the width of meniscus to that of tibial plateau≥0.20, and the thickest thickness of the meniscus posterior horn≥4.40 mm.Medial discoid meniscuses are divided into complete and incomplete type; the lesion rate of complete type of medial discoid meniscus is higher than that of the incomplete type.
目的:分析汶川大地震中伤员骨盆骨折的发生部位及骨折类型。方法:对地震发生后近2个月内先后送至四川大学华西医院治疗的95例骨盆骨折伤员,按放射学检查结果进行骨折部位及类型分析。结果:95例伤员共发生133个部位的骨折。按骨折部位分类:髂骨22个(16.6％),坐骨10个(7.5％),耻骨81个(60.9％),髋臼18个(13.5％),骶尾骨2个(1.5％)。按骨折类型分类:斜行骨折71个(53.4％),粉碎性骨折43个(32.3％),线性骨折11个(8.3％),横行骨折5个(3.7％),嵌插骨折3个(2.3％)。结论:地震造成骨盆骨折部位以耻骨为主,类型以斜行骨折为主。对骨盆骨折伤员,X线及CT检查相结合能为临床提供更好的影像诊断价值。
目的：总结胸腺类癌的临床表现、病理特征、CT表现及其临床价值。方法：对本院收治的2例胸腺类癌进行分析并结合文献复习。结果：胸腺类癌发病率低，大部分早期患者无临床症状，经胸部X线、CT检查时发现；中晚期始出现症状。病理检查出类癌后，电镜可见神经内分泌颗粒，免疫组化显示神经特异性烯醇化酶、肿瘤嗜铬蛋白A、促皮质素阳性。胸部CT表现特征为起于前上纵隔肿块，常位于心底部大血管和心包周围，肿块内密度不均，可见钙化，增强后轻中度强化，易发生胸内外转移。结论：胸腺类癌是一罕见的前纵隔肿瘤，根据CT特征，结合临床可有助诊断、指导手术、推测预后，因此CT在临床诊治中有非常重要的价值。
