Abstract:
[Objective]To investigate the value of"pericardium crescent sign"in the diagnosis of non-calcified con-strictive pericarditis in CT.[Methods]Twenty-seven patients with non-calcified constrictive pericarditis and forty-six cardiac tumors confirmed by surgical pathology were analyzed retrospectively. All patients underwent non-enhanced and enhanced CT scan preoperatively.Pericardial morphology,density,enhancement features,appearance of atrium,ventri-cle and inferior vena cava of non-calcified constrictive pericarditis were analyzed. Pericardial morphology of cardiac tumors was also analyzed.[Results]Of the 27 patients with non-calcified constrictive pericarditis,18 patients developed"pericardium crescent sign",accounting for 66.7%,ventricular varying degrees of deformation in 13 cases,accounting for 48%;venous dilatation in 26 cases,accounting for 93%;atrial enlargement in 7 cases,accounting for 26%. In 46 patients with cardiac tumors,only 1 patient had a similar"pericardial crescent"sign.For the diagnosis of constrictive pericarditis using pericardial crescent sign,the sensitivity was 66.7%,the specificity was 97.8%,Youden index was 0.64. The area under the ROC curve was 0.82([0.71-0.94],P<0.001).[Conclusion]"Pericardium crescent sign"is important CT features of non-calcified constrictive pericarditis. It has high specificity for differentiating non-calcified constrictive pericarditis from pericardial tumor imaging.
