CT diagnosis of cardiac lipoma / 中华放射学杂志

ABSTRACT

Objective To investigate the application of CT in the diagnosis of cardiac lipoma.Methods Retrospective analysis of 6 patients with cardiac lipoma confirmed by operation and pathology was done. Four patients had singles slice electron beam CT plain and contrast and movie scan. Two patients had 64-slice CT plain and enhanced scan. Results (1) One patient was isolated intracavitary lipoma in the right artium, 1 patient was isolated intrapericardial lipoma and 4 patients were intramural lipomas. Of the 4 intramural lipoma, 2 were infiltrative lipomas located in the left ventricle wall or the right ventricle and septum, 2 patients were isolated in the atrio-ventricular septums. (2) CT and three-dimensional reconstruction could depict the location, shape, size, margin and characteristic fat density of lipoma,indicating the diagnosis and classifications. The displacement of coronary artery, pulmonary inflammation and effusions of pericardium and pleural cavity could also be revealed. Conclusion Cardiac lipoma can be accurately diagnosed and classified by CT.
