CT成像及MPR在诊断心脏脂肪瘤中的应用价值

Applied value of CT scanning and MPR in the diagnosis of cardiac lipomas

目的评估CT诊断心脏脂肪瘤的应用价值。方法回顾性分析经手术病理证实的12例心脏脂肪瘤的CT表现,并与部分病灶病理所见对照。结果 CT诊断右心房型孤立性脂肪瘤2例,心包内型孤立性脂肪瘤2例,肌壁型脂肪瘤8例。CT成像与MPR不但能清晰显示心脏脂肪瘤的位置、形态、大小、边缘和特征性的脂肪密度,提示肿瘤的诊断及分型,并且对并存的冠状动脉受推压移位、肺部感染、心包和胸腔积液等异常征象均可同时显示。结论 CT检查对心脏脂肪瘤的诊断及分型具有很高准确性,应作为诊断本病的重要方法。

Objective To assess the applied value of conventional CT scanning and multiplanar reformation（MPR） in the diagnosis of cardiac lipomas.Methods Twelve patients with surgically and pathologically proved cardiac lipoma underwent conventional CT scanning and MPR.CT findings of all patients were retrospectively analyzed and partially compared with postoperative pathology.Results Among 12 patients,conventional CT scanning and MPR accurately diagnosed solitary lipomas of right atrial pattern in 2 cases,solitary lipomas of intrapericardial pattern in 2 cases,and solitary lipomas of muscular wall pattern in 8 cases.Plain CT scanning and MPR could not only clearly visualize the site,shape,size,margin,and specific fatty density of cardiac lipomas,suggest diagnosis and typing of the tumor but could simultaneously find the varied complications of cardiac lipomas,such as compression and displacement of coronary arteries,pulmonary infections,hydropericardium and hydrothorax etc.Conclusion CT examinations in the diagnosis and typing of cardial lipoma have high accuracy,which should be the important modality of diagnosing this disease.
