Abstract

The clinical manifestation of pericardial disease is similar to that of coronary artery disease and aortic disease. Therefore, a timely and accurate diagnosis is necessary. The pericardium is a 2-layered membrane that envelops the heart and great vessels, and there are numerous anatomic variations and pathologic conditions. Large or unusually located pericardial recesses can be easily mistaken for abnormal findings. Additionally, primary pericardial diseases resulting from infections, tumors, and injuries are possible; further, diseases can quickly spread along the pericardium. Echocardiography is generally the first imaging tool used to evaluate the pericardium. However, it has limited windows and poor resolution. Besides, the evaluation of postoperative echocardiography is sometimes limited. Currently, CT and MR imaging are useful for evaluating pericardial diseases. Detailed knowledge of the pericardium is important for interpreting the images and clinical results.

심막 질환은 응급질환인 관상동맥, 대동맥 질환과 증상이 비슷하여 빠른 감별이 중요하다. 심막은 두겹으로 된 막으로서 다양한 해부학적 변이와 질환이 있다. 크거나 비전형적인 위치를 보이는 심막의 오목(recess)은 이상 소견으로 오인될 수도 있다. 심막에는 감염이나 종양 같은 질환이 생기며 또한 주변에서 생기는 이러한 질환의 전파경로가 될 수 있다. 심막을 평가하는데 있어 심초음파가 일차적인 검사방법이나 해상도가 떨어지고 주변의 폐나 뼈에 의한 음창이 제한될 수 있으며 수술 후 평가가 힘든 경우가 많다. 이때 CT나 MR에 의한 영상평가가 유용한 경우가 많아 검사가 점점 늘어나고 있다. 심막의 형태와 질환에 대한 지식 및 영상소견에 대한 이해는 환자 치료에 중요하다.
