T淋巴母细胞瘤/白血病的胸部CT表现

Chest CT Manifestations of T-lymphoblastoma/Leukemia

目的探讨T淋巴母细胞瘤/白血病的CT影像学特征。方法回顾性分析自2012年1月至2021年7月在中山大学孙逸仙纪念医院首诊的23例T淋巴母细胞瘤/白血病MSCT表现,分析纵隔肿块,胸腔积液,心包积液,心腔低密度及肺部浸润等特征。结果23例中,病变仅限于前纵隔4(4/23)例;前、中纵隔11(11/23)例;纵隔肿块大小不一;肿块多发13(13/23)例,单发1(1/23)例;平扫呈软组织密度;23例中6例增强扫描,4例肿块轻度均匀强化,1例肿块中度均匀强化,1例肿块中度渐进性强化;肿块质地均匀;侵犯胸腺,主动脉、肺动脉、颈内动脉及静脉呈包绕为主,移位较轻,与血管边界模糊。胸腔积液9(9/23)例,心包积液6(6/23)例;心腔低密度10(10/23)例;肺部浸润14(14/23)例,病变仅限肺部浸润8(8/23)例,2例肺部浸润表现为右肺下叶实变。结论T-LBL/ALL病纵隔肿块,合并胸腔、心包积液、心腔低密度,可提高对该病的诊断。

Objective To investigate the CT imaging features of T lymphoblastoma/leukemia.Methods From January 2012 to July 2021,the MSCT manifestations of 23 T lymphoblastoma/leukemia patients who were first diagnosed in Sun Yat-sen Memorial Hospital of Sun Yat-sen University were retrospectively analyzed.density and pulmonary infiltrates.Results Among the 23 cases,the lesions were limited to the anterior mediastinum in 4(4/23)cases;the anterior and middle mediastinum in 11(11/23)cases;the mediastinal masses were of different sizes;13(13/23)cases had multiple masses,and 11(1/23)cases;plain scan showed soft tissue density;6 cases of 23 cases with enhanced scan,4 cases of mild homogeneous enhancement,1 case of moderate homogeneous enhancement,1 case of moderate progressive enhancement;uniform texture of the mass;invasion The thymus,aorta,pulmonary artery,internal carotid artery and vein were mainly surrounded,slightly displaced,and blurred with blood vessels.There were 9(9/23)cases of pleural effusion,6(6/23)cases of pericardial effusion;10(10/23)cases of cardiac cavity hypodensity;14(14/23)cases of pulmonary infiltrates,and the lesions were limited to the lungs There were 8(8/23)cases of infiltration,and 2 cases of pulmonary infiltrates showed consolidation in the lower lobe of the right lung.Conclusion Mediastinal mass in T-LBL/ALL disease combined with pleural cavity,pericardial effusion and low density of cardiac cavity can improve the diagnosis of the disease.
