Abstract: Constrictive pericarditis is caused by acute or chronic pericarditis in delayed healing and the tuberculosis(TB) is the main pathogenic bacteria. Pericardial thickening adhesions, fibrosis, with or without calcification are the most common imaging performance. Clinically, it is not difficult to make diagnosis through medical history and imaging. The main points of diagnosis are tuberculosis history, tuberculous serous effusion, tuberculous experimental examination, pericardium constriction, pericardium thickening and adhesion to constricted fibrous bands. Especially the imaging presentation with pericardial thickening or calcification is typical sign of diagnosis of the disease. The clinical and imaging feature in this case are not obviously that the pericardium did not show the typical signs of adhesion and calcification. Therefore, early diagnosis of constrictive pericarditis is extremely challenging. The combination of multimodality cardiac magnetic resonance examination can not only clarify the pericardium condition and cardiac changes, but also make a comprehensive quantitative assessment of cardiac structure, function and movement abnormalities caused by constrictive pericarditis, so as to provide more imaging evidence for early diagnosis of the disease and further to reduce misdiagnosis rate.
