Objective To study the imaging characters of pericardial cysts. Methods 38 cases with pericardial cyst rnconfirmed by operation and pathology were reported. There were X-ray materials in all of the patients, CT in 15 cases,rnMRI in 2 cases, Ultrasound (US) in 10 cases. Results The lesions located in right cardial phrenic angle 53.3%,left rncardial phrenic angle 31.6%. Round and oval shape 78.9%, irregular shape 21.1%; smooth outline 76.3%, irregularrn23.7%; homogeneous density 94.7%, with calcification 5.3%. The CT value was 0～18Hu, calcification 128Hu.rnMRI showed lower intense signal in T1WI and super intense in T2WI with the capsular were clear. US showed typical rnimaging features of cyst including fluid. Conclusion Pericardial cyst has typical imaging characters, it was suggested rnthat correct diagnosis can be made through combing different imaging procedures with clinical findings.%目的总结纵隔心包囊肿的影像学特征。方法本文报告经手术与病理证实的心包囊肿38例。全部病例均有完备的X线资料，其中行CT检查15例，MRI检查2例，超声检查10例。结果病变发生在右心膈角区占55.3％，左心膈角区31.6％，余者位置不典型。圆形和椭圆形78.9％，不规则形21.1％。边缘光滑整齐76.3％，不整齐23.7％。密度均匀94.7％，有钙化者5.3％。囊肿的CT值为0～18Hu，钙化处高达128Hu。MRI见囊肿T1WI为低信号，T2WI为高信号，其包膜显示清楚。B超见其为有包膜的含液囊性肿物。结论心包囊肿具有典型的影像学特征，综合应用各种影像学方法，结合临床可做出正确诊断。
